DGM (MP) was entrusted for scout drilling. The results of the scout
drilling conducted by DGM (MP) revealed presence of good quality
workable coal deposit in an area of about 60 sq.km of the intervening
Amadand tract between the working mines of SECL.
Detailed exploration of the area was taken up by CMPDI in August 1990
and comprehensive geological information was provided in Geological
reports on Bartarai Block in December 1993, Amadand Opencast area in
December 1995, Bakulmuni Block in July 1997, Amadand East U/G Block
in January 1998 and Amadand West U/G Block in November 1999. The
block measures 15.061 sq.km. which includes 14.154 sq.km. free area
and 0.907 sq.km. forest area.
The borehole density within the block is 15.20 BH / sq km.
1.4 JUSTIFICATION OF PREPARATION OF RPR
Amadand OC (1.15 Mty) was prepared with an average stripping ratio of
4.58 cum/t considering only upper seam i.e UK. Later on, decisions were
taken to extract coal from bottom seams upto bottom most LK-II seam.
Accordingly, this report is formulated considering all the seams upto bottom
most LK-II seam for mining with outsourcing option.
Liberalisation of power sector by Government of India has generated
wide spread interests for private and public sector investments in power
generation and other industrial development. As such, there is an
appreciable increase in the number of upcoming new projects in both
private and public sectors. The demand projection from SECL for the
year 2015-16 is 269.97 Mt, as given in Table 2.1. It will cater to the needs
of the upcoming industries like power, Cement, Fertilizers, other
industries etc. The demand projection from SECL for the year 2016-17
is 270.37 Mt. The projected availability in the year 2016-17 is 150.00 Mt
and there will be shortage of 120.37 Mt.To meet the demand of coal, it is
required to open new projects.

JOB NO.-515126 ES / 6 of 39
Both winning of coal and extraction of OBR will be done through outsourced
HEMM. PR is giving IRR 13.55% at 85% level of production. The overall grade
of coal is “grade G-8” with GCV 4933 Kcal/Kg, which is easily marketable. As
per the guidelines, a Project is economically viable when it achieves more than
12% IRR at 85% level of Production. Since, this Project is having Internal Rate
of Return more than 12% at 85% level of target production i.e. 13.55% and
hence Outsourcing Option of this project is economically viable project.
The outsourcing option of RPR for Amadand Opencast Project (4.00Mty)
was placed before SECL Board’s 236th meeting held at Raipur on dated
04.09.2015 for a total capital of Rs 869.44 Crores and SECL Board directed to
submit the same to CIL, since capital provision in the RPR exceeds Rs 500
Crores.
Accordingly, RPR for Amadand Opencast Project (4.00Mty) was placed
before 325th CIL Board meeting held at Kolkata on dated 05.03.2016 for a total
capital of Rs 869.44 Crores. CIL Board accorded its approval to Project Report
for Amadand Opencast Project for a rated capacity of 4.00 Mty at an estimated
capital investment of Rs 869.44 Crores for implementation of the project with
total outsourcing variant i.e both coal and OB outsourcing.
1.5 DIFFICULTIES AND CONSTRAINTS IN MINING WITH ASSOCIATED RISK
(i) The nearest railway siding is Govinda Railway siding which is
situated at a distance of about 5.0Km from the mine. The railway
line extension from Bhaiyatola station is required to connect the
upcoming Amadand siding.
(ii) Rehabilitation & resettlement of four villages namely Nimha,
Timkitola-Amadand, Harratola-Kuhka and Majholi are involved in
the project. Acquisition of land alongwith R&R of PAP is a critical
activity and should be taken up on top priority.
1.6 PEAK CAPACITY Sometimes with favorable geo-mining conditions and improved
productivity of the HEMM, the project may produce coal upto 1.35 times of
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 7 of 39
the planned capacity. So, EMP should be prepared for 5.40 Mty,
accordingly approval from the Competent Authority is to be sought.
1.7 FLEXIBILITY IN IMPLEMENTATION The flexibility in the implementation stage may be exercised within the
approved cost estimates to respond to improvements in technology and
equipment which would result in improved profitability and productivity
measures. Following points may be considered under the flexibility: -
a) Re-alignment of project working for better working layout / dump etc.
b) Change in the specification of HEMM, for techno-economic consideration,
to higher capacity at the time of procurement of new equipment or
replacement of the equipment.
c) To procure state-of-the-art safety equipment, whenever they are
introduced, even if the same is not provided in approved Project Report.
d) Relocation of site for infrastructure facilities depending upon techno-
economic reasons and availability of land / forest area etc.
e) Hiring of equipment for loading, transportation etc., at a competitive price,
so as to cater to the needs of increased demand of coal and subsequent
removal of higher OB and for augmentation of coal production.
f) For upgradation of new technology in mining method for improving
performance and reduction in manpower, at a subsequent date after
project completion.
g) In this PR it is proposed that coal would be mined by surface miner.
However, in circumstances where Operational/Geotechnical difficulties
persist small quantity of coal may be mined out by alternative technology
such as ripping/drilling etc. Prior approval may be obtained for use of
alternative technology citing the circumstances/operational difficulties.
1.8 CRITICAL ACTIVITIES PRIOR TO ENVIRONMENT CLEARENCE
Critical activities, which could be taken up prior to environmental, forestry
and other statutory clearances to expedite project implementation are as given
below.
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI

a) Northern boundary of quarry is to be exposed upto UK seam along the
full strike length of the quarry. This is required to reach quarry floor of 4.0
Mty report to create internal dumping space at the earliest.
b) The acquisition of R&R site should be processed to take possession of
the R&R site to rehabilitate the project affected family at the earliest.
c) The northern side garland drain is to be constructed first to prevent inrush
of water from northern side. As quarry advances towards the south, the
other garland drains will be constructed as per requirement.
d) Preliminary study about extension of railway line and its tentative
alignment from Bhaiyatola rail station or other suitable location is to be
done to connect Amadand Siding.

5.1 MINE BOUNDARIES
The quarriable area for the opencast mining is shown on Plate No.3 &
Figure-5.1. One quarry on floor of Seam LK-II has been planned. The
boundary of quarry has been fixed as follows: -
North : Incrop of Upper Kotma Seam
Reason- Beyond UK seam incrop the stripping ratio is
high (more than 20).
South : Incrop of Upper Kotma Seam
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 11 of 39
Reason- Beyond UK seam incrop the stripping ratio is
high (more than 20).
East : A line keeping 100 m barrier from boundary of Amadand
Village and Pendra-Manendragarh road.
Reason-. Amadand UG and Bartarai UG mine is operating
on the other side of road.
West : Incrop of Upper Kotma Seam
Reason- Beyond UK seam incrop the stripping ratio is high
(more than 20).
Khodri Block has not been included in the proposed mine area. The
incrop of coal seams also exists in the northern side of Khodri Block.
Thus, Khodri Block can be extracted from the northern side of the block
as a separate mine.
5.2 MINEABLE RESERVES
As on 01.04.2015, the total mineable reserves within the quarry have
been estimated as 70.46 Mt with a corresponding OB volume of 764.40
Mcum. The already extracted coal & OB removal has been deducted to
get the balance remaining coal & OB quantity. While, calculating
mineable reserves, a geological loss of 10% and a mining loss of 10%
have been considered.

of the haul road has been kept as 30 m for two way dumpers transport. Two
batter road of 50m width will be maintained along UK seam & MK seam for
laying side road and inpit belt conveyor.(details given in chapter 11)
6.3 EQUIPMENT SELECTION
In this PR, Coal and OB is proposed to be worked by outsourced
equipment. OB is proposed to be excavated by shovel dumper
combination. It is envisaged that coal would be mined by surface miner. In
this PR it is proposed that coal would be mined by surface miner. However,
in circumstances where Operational/Geotechnical difficulties persist small
quantity of coal may be mined out by alternative technology such as
ripping/drilling etc. Prior approval may be obtained for use of
alternative technology citing the circumstances/operational difficulties.
In the outsourcing option blasting will be done departmentally and
both OB and coal will be worked by outsourcing. To handle the larger OB
quantity optimum no. of equipment with optimum capacity is proposed be
used. Due to flexibility of operation, Shovel-Dumper combination will be
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 14 of 39
suitable for OB removal for working multiple seams and partings.
Considering huge volume of OB removal higher size of HEMM like 10
cum Shovels with 100T rear dumpers may be used for OBR by
outsourcing agency. For thin partings, smaller backhoe may be used.
Few auxiliary HEMM has been given for mine development and
reclamation related work. Transport of coal from face to railway siding
will be done by inpit belt conveyor & surface belt conveyor.
The property is free from any major geological disturbances. Average
gradient of quarry floor is 1 in 30. The average strike length of the quarry
is 3.0 km. Thus, sufficient face length will be available for optimum
efficiency of surface miner.
The bottom most seams LK-2 have been splitted into LK-2 Top and LK-2
Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m.
Above LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to
0.90m. Parting thickness between Seam LK-2 and L-1 varies 6 m to 18
m. Thus, dragline horizon changing will be required for operation of
dragline and dragline productivity will be less. Besides, the bottom coal
bench may be diluted as low thickness coal seam may be mixed with OB
during dragline operation. Considering multi-seam working and wide
variation of parting OB, dragline has not been proposed in this Project
Report.
6.4 MINING SYSTEM & SYSTEM PARAMETERS
Surface miner has been proposed for extraction of coal.
The salient features of mining system are as follows:-
i) Height of bench in OB will depend on the size of equipment.
Coal bench height will depend on the thickness of the coal seams.
The provision of coal mine regulations and related circulars shall be
strictly followed for designing bench parameters in coal and OB.
ii) Average Seam gradient – 1 in 30.
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 15 of 39
iii) Total dump height – Internal dump height is 230 m from quarry
floor but it will be 90m from surface. External dump height is 120m
from surface.
7.1 CONSTRAINTS ON MINE DEVELOPMENT (i) The nearest railway siding is Govinda Railway siding which is
situated at a distance of about 5.0Km from the mine. The railway
line extension from Bhaiyatola station is required to connect the
upcoming Amadand siding.
(ii) Rehabilitation & resettlement of four villages namely Nimha,
Timkitola-Amadand, Harratola-Kuhka and Majholi are involved in
the project. Acquisition of land alongwith R&R of PAP is a critical
activity and should be taken up on top priority.
7.2 MINING STRATEGY / MINING SEQUENCE
At present Amadand OC is a running mine with a peak coal production of
1.15Mty and it is already extracting coal from UK seam.
It is proposed to expose MK seam in the 2nd year of mine operation by
grading properly the access trench and making its width 30 m wide and
gradient at 1 in 16. Then sufficient area to be exposed in the MK seam
floor. In the 3rd year of mine operation, the access trench is to be graded
at 1 in 16 to touch the mine floor at LKII seam of about 405 m R.L.
The quarry floor is developed in such a manner so as to facilitate
the proper drainage of water towards the sump. This would also facilitate
extension of coal and OB bench for full development of mine. After
creation of sufficient decoaled area, internal backfilling of OB will be
started in the 4th year. The coal production will continue from the 1st year
of mine life and the target coal production of 4.00 Mty will be achieved in
the 3rd year.
Two batter road of 50m width will be maintained along eastern side
batter. One batter road along floor of UK seam will be used to place inpit
belt conveyor to carry coal from UK & L4 seam as shown in plate 3.
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 16 of 39
Other batter road along floor of MK seam will be used to place inpit
belt conveyor to carry coal from MK, L3 & LK1 seam. One another
inclined inpit belt conveyor will be placed upto floor of LKII seam to carry
coal from LKII & L1 seam.
Finally, through inclined belt conveyor all the coal will be transported to
surface as shown in the plate-3. From pit top coal will be transported to
upcoming Amadand siding through surface belt conveyor. .(details given
in chapter 11)
For reducing the external dump area and healthy operation of mine, 2
plans i.e. final stage of mine excavation and final dump plan showing
backfilling, Plate No. 3 & 4 are enclosed. The life of mine will be 19 years.
7.3 TOP SOIL MANAGEMENT Initially, the soil/alluvium from top bench of OB will be stacked and stored
separately. The stock piling of topsoil will be as follows:
i) Top soil removed shall be stock-piled till sufficient area is making
available to spread such materials immediately on re-graded
areas.
ii) Stock-piled Top soil shall be selectively placed on a stable area,
not disturbed, and protected from wind and water erosion,
unnecessary compaction, and contaminants which lessen the
capability of the materials to support vegetation when redistributed.
iii) After the final grading the stacked top soil would be redistributed
in a manner that achieves an approximate uniform stable
thickness consistent with the post mining land uses, contours,
and surface water drainage system.
The top soil quantity will be about 3.0Mcum. Provision of placing of
top soil over final dump has been considered in project costing.
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 17 of 39
7.4 DUMPING STRATEGY In the initial years i.e. upto 4th year, entire OB will go to the external
dumps. For project implementation and aquision of land for external
dump may take 3 to 4 years. During this period about 20 Mcum OB will
be dumped internally. Provision of rehandling of this internal dump to
external dump site has been considered in the project costing.
Internal dumping will start from the 4th year onwards. The parting OB in
case of older seams may be transported partly through central haul road,
while mining in the multi seam zone.
Initially, the soil/alluvium from top bench of OB will be stacked and stored
separately. The spoil dump benches in the internally backfilled OB will be
in the form of benches. With the sufficient advance of coal production
bench, the backfilled OB will be leveled with dozer.. Dumper/Tipper will
transport soil/alluvium OB from the top OB bench and will dump the soil
directly on the leveled backfilled OB. The barrier distance between
internal dump and coal production bench will be 100 m to have smooth
functioning of machineries.
The slope stability study should be done. According to study report, the
dump design like dump bench height, total dump height & slope etc.
should be modified to avoid dump failure. In addition to that proper
precautions should be taken to avoid sliding of internal OB bench. is
estimated that 238.02 Mcum OB will be externally dumped outside quarry
area from 1st year to 10th year for which 356.50 Ha land will be required.
The northern boundary of Amadand OC block is along the Fault F1-F1
having throw of 20m to 80m. On the other side of Fault F1-F1 Khodri
Block exists where UK seam occurs at a minimum depth of about 21m.
So external dump has not proposed in the Khodri Block.
External dump has been made near southern boundary as shown in
Plate No.4. The break-up of OB quantity to be accommodated in various
dumps is as follows:-
RPR for Amadand OCP (4.0 Mty) (Updated July’2015) CMPDI
JOB NO.-515126 ES / 18 of 39
Dump OB accommodated in Mcum 1. Internal dump 526.38 2. External dump outside Quarry area 238.02
Top soil will be removed and stored separately. This soil will be directly
spread over the leveled graded backfilled spoil for reclamation of the
quarried out land.
Possibility of external dump within quarry boundary and rehandling back
into the quarry has been examined. Considering the high quantity of
external OB placing of external dump within quarry boundary will not to
be feasible. So placing of external dump proposed outside the quarry
area.
Amadand OC may be expanded in the east direction. Quarry planning
and dump plan has been proposed accordingly such that quarry can be
expanded in east directions in future. At the end of quarry life, if required,
the void left will be filled to reduce the depth of void to 60m. Necessary
filling of the void will be done from mine closure cost. Initially the height of
internal dump is 90m from surface. After ffteenth year of mine life the
internal dump height will be kept upto surface level. Thus after mining is
over, about 228.18 Ha land will be levelled to surface level and can be
utilized for agricultural purposes.

18.11 MINE CLOSURE COST
The mine closure cost will cover the various related activities for which a
corpus escrow account @ Rs. 6.0 lakh per Ha for Opencast mine of the
project area shall be opened with the coal controller organization. The
above amount is as per the mine closure guidelines issued in August
2009, which will be updated for the present financial year based on the
cost index value.
18.11.1 Mine Closure Cost for OC mine
As per the guidelines of the MoC, the cost of the mine closure is to be
computed on the basis of the project area involved in the project. In
Amadand OCP total land area involved is 1443.005 Ha. The updated
cost of the mine closure as on March’15 is estimated to be Rs. 8.15 lakh
per hectare (considering the admissible escalation over Rs. 6.00 lakh per
Ha as on August 2009).
Final mine closure cost @ Rs = W.P.I of March 2015 176.10 /W.P.I of
Aug.09 129.60 x 6= Rs.8.15 Lakh/ Ha. for 1443.005 Ha = Rs.11760.491
lakhs.

CHAPTER – I INTRODUCTION
1.1 BACKGROUND OF THE PROJECT REPORT
The Amadand Opencast Block is located in the eastern part of south Sohagpur
Coalfield and is flanked by working mines of Hasdeo and Jamuna & Kotma
areas of South Eastern Coalfields Limited (SECL) to the east and west
respectively.
The detailed exploration of the area was taken up by CMPDI in August 1990
and comprehensive geological information were provided in Geological Reports
on Bartarai Block in December 1993, Amadand Opencast area in December
1995, Bakulmuni Block in July 1997, Amadand East U/G Block in January 1998
and Amadand West U/G Block in November 1999.
Project Report for Amadand OC (1.15 Mty) was prepared with an average
stripping ratio of 4.58 cum/t considering only upper seam i.e UK seam and
submitted to SECL in August 2003 and approved in Sept 2003. During
preparation of Amadand OC (1.15 Mty) report, lower seams e.g. MK (Top) and
MK (Bottom) and LK-II were also considered for extraction by opencast
method. But, due to high stripping ratio, the quarriability of lower seam were not
feasible for departmental option. So seams below UK seam were not
considered in the 1.15 Mty PR.
Latter on, decisions were taken to extract coal from bottom seams.
Accordingly, Revised Geological Report have been prepared, considering
workable coal seams upto bottom most LK-II seam which has not taken into
account for opencast mining earlier. In the area under consideration seams, L-
6, L-5, UK (Top), UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK (Top),
MK (Bottom), MKC, L-2, LK-I, L-1, LK-II (Top), LK-II (Bottom) & LK-II have
encountered in descending order.
The present report is formulated considering all the seams upto bottom most
LK-II seam for mining with outsourcing option.

1.2 EXPLORATION STATUS
The area was identified by CMPDI for scout drilling in March 1989 on the basis of
some boreholes drilled close to some of the GSI boreholes, namely, SM-4, 6&8
etc. in the eastern part of the Amadand tract and DGM (MP) was entrusted for
scout drilling. The results of the scout drilling conducted by DGM (MP) revealed
presence of good quality workable coal deposit in an area of about 60 sq.km of
the intervening Amadand tract between the working mines of SECL.
Detailed exploration of the area was taken up by CMPDI in August 1990 and
comprehensive geological information was provided in Geological reports on
Bartarai Block in December 1993, Amadand Opencast area in December 1995,
Bakulmuni Block in July 1997, Amadand East U/G Block in January 1998 and
Amadand West U/G Block in November 1999.
The block measures 15.061 sq.km. which includes 14.154 sq.km. free area
and 0.907 sq.km. forest area. The borehole density within the block is 15.20 BH /
sq km.
1.2.1 History of the Block
Project Report for Amadand OC (1.15 Mty) was prepared with an average
stripping ratio of 4.58 cum/t considering only upper seam i.e UK seam and
submitted to SECL in August 2003 and approved in Sept 2003.

The PR has been formulated to win coal by Surface Miner with FEL and
trucks/dumpers & OB by Shovel Dumper combination. Transport of coal from face
to railway siding will be done by inpit belt conveyor & surface belt conveyor.
Both winning of coal and extraction of OBR will be done through outsourced
HEMM. PR is giving IRR 13.55% at 85% level of production. The overall grade of
coal is “grade G-8” with GCV 4933 Kcal/Kg, which is easily marketable. As per the
guidelines, a Project is economically viable when it achieves more than 12% IRR
at 85% level of Production. Since, this Project is having Internal Rate of Return
more than 12% at 85% level of target production i.e. 13.55% and hence
Outsourcing Option of this project is economically viable project.
The outsourcing option of RPR for Amadand Opencast Project (4.00Mty) was
placed before SECL Board’s 236th meeting held at Raipur on dated 04.09.2015 for
a total capital of Rs 869.44 Crores and SECL Board directed to submit the same to
CIL, since capital provision in the RPR exceeds Rs 500 Crores.
Accordingly, RPR for Amadand Opencast Project (4.00Mty) was placed before
325th CIL Board meeting held at Kolkata on dated 05.03.2016 for a total capital of

1.6 DIFFICULTIES AND CONSTRAINTS IN MINING WITH ASSOCIATED RISK
(i) The nearest railway siding is Govinda Railway siding which is situated
at a distance of about 5.0Km from the mine. The railway line extension
from Bhaiyatola station is required to connect the upcoming Amadand
siding.
(ii) Rehabilitation & resettlement of four villages namely Nimha, Timkitola-
Amadand, Harratola-Kuhka and Majholi are involved in the project.
Acquisition of land alongwith R&R of PAP is a critical activity and
should be taken up on top priority.
1.7 PROJECT OBJECTIVES AND TARGET BENEFICIARIES The demand projection from SECL for the year 2016-17 is 270.37 Mt. It will cater
to the needs of the upcoming industries like Cement, Fertilizers, other industries
etc. The projected availability in the year 2016-17 is 150.00 Mt and there will be
shortage of 120.37 Mt as shown in Table 2.1. .
1.8 PEAK CAPACITY Sometimes with favorable geo-mining conditions and improved productivity of the
HEMM, the project may produce coal upto 1.35 times of the planned capacity. So,
EMP should be prepared for 5.40 Mty, accordingly approval from the Competent
Authority is to be sought.
1.9 FLEXIBILITY IN IMPLEMENTATION The flexibility in the implementation stage may be exercised within the approved
cost estimates to respond to improvements in technology and equipment which
would result in improved profitability and productivity measures. Following points
may be considered under the flexibility: -
a) Re-alignment of project working for better working layout / dump etc.
b) Change in the specification of HEMM, for techno-economic consideration, to
higher capacity at the time of procurement of new equipment or replacement of
the equipment.
c) To procure state-of-the-art safety equipment, whenever they are introduced,
even if the same is not provided in approved Project Report.
d) Relocation of site for infrastructure facilities depending upon techno-economic
reasons and availability of land / forest area etc.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 1 / 11 of 11
e) Hiring of equipment for loading, transportation etc., at a competitive price, so as
to cater to the needs of increased demand of coal and subsequent removal of
higher OB and for augmentation of coal production.
f) For upgradation of new technology in mining method for improving
performance and reduction in manpower, at a subsequent date after project
completion.
g) In this PR it is proposed that coal would be mined by surface miner. However,
in circumstances where Operational/Geotechnical difficulties persist small
quantity of coal may be mined out by alternative technology such as
ripping/drilling etc. Prior approval may be obtained for use of alternative
technology citing the circumstances/operational difficulties.
1.10 CRITICAL ACTIVITIES PRIOR TO ENVIRONMENT CLEARENCE
Critical activities, which could be taken up prior to environmental, forestry and
other statutory clearances to expedite project implementation are as given below.
a) Northern boundary of quarry is to be exposed upto UK seam along the full
strike length of the quarry. This is required to reach quarry floor of 4.00 Mty
report to create internal dumping space at the earliest.
b) The acquisition of R&R site should be processed to take possession of the
R&R site to rehabilitate the project affected family at the earliest.
c) The northern side garland drain is to be constructed first to prevent inrush of
water from northern side. As quarry advances towards the south, the other
garland drains will be constructed as per requirement.
d) Preliminary study about extension of railway line and its tentative alignment
from Bhaiyatola rail station or other suitable location is to be done to connect
Amadand Siding.

GEOLOGY AND DEPOSIT APPRAISAL
4.1 INTRODUCTION
4.1.1 The Amadand Opencast Block is located in the eastern part of south Sohagpur
Coalfield and is flanked by working collieries of Hasdeo and Jamuna & Kotma
areas of the SECL to the east and west respectively.
The area was identified by CMPDI for scout drilling in March 1989 on the basis
of some boreholes drilled close to some of the GSI boreholes, namely, SM-4,
6&8 etc. in the eastern part of the Amadand tract and DGM (MP) was entrusted
for scout drilling. The results of the scout drilling conducted by DGM (MP)
revealed presence of good quality workable coal deposit in an area of about
60sq.km. of the intervening Amadand tract between the working collieries of
SECL.
A detailed proving of the area was taken up by CMPDI in Aug.1990 and a
comprehensive geological information was provided in Geological Reports on
Bartarai Block in Dec.'93, Amadand Opencast area in Dec.'95, Bakulmuni Block
in July'97, Amadand East U/G Block in January 1998 and Amadand West U/G
Block in Nov.’99.
The Amadand Opencast Area has been prepared after considering the Upper
Kotma seam only. However, the present report is prepared at the behest of
Mining Department, considering the area of aforesaid 4 reports in part or total
from the opencast stand point considering all the seams. Accordingly the data
have been re-processed, boreholewise from underground norms to opencast
norm and many coal seams and/coal bands intersected in boreholes, earlier not
taken into account, have been considered along with their naming. Wherever
necessary, earlier splits of seams have been merged, as per the revised norms
considered for opencast mine. In the area of present seams, L-6, L-5, UK (Top),
UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK (Top), MK (Bottom),

4.2.4 Reliability of data and degree of confidence (based on statistical analysis)
1) In the absence of any surface exposure of the strata, the report is based
entirely on the data obtained from 228 boreholes drilled by CMPDI and
DGM (MP) falling within Amadand OC Block.
2) The area shows variable dip, and the area is devoid of fault. However, the
possibility of faults of smaller magnitude cannot be entirely ruled out in the
area. Though all care has been taken to precisely delineate the incrops of
seams on the basis of borehole data, there is a possibility of minor
variation as the exact pattern of local weathering is not known.
3) The statistical analysis of borehole data has been carried out separately for
different seams for estimating Mean and Standard Deviation of different
parameters is given below:

4.3.2 Coal bearing formations
The coal bearing Barakar Formation is mainly composed of greyish white, fine to
medium grained loosely compact sandstone with occasional coarse grained
sandstone. Moreover, grey shale, sandy shale and carbonaceous shale with coal
bands are found to occur in the Formation. The thickness of preserved section of
Barakar in the area is about +224m. The potential workable coal horizons are
restricted to the top 140m while the lower 110m of Barakar strata is devoid of
workable coal horizons.
Eighteen coal seams viz. Seam L6, L5, UKT, UKB, UK, L4, L3T,L3B, L3, MKT,
MKB, MKC, L2, LKI, L1, LKIIT, LKIIB and LKII in descending order occur in
Barakar Formation.

4.3.4 Structural setting within the project area
The featureless rolling topography and a thick soil cover in and around Amadand
Open Cast Block have completely masked the surface expression of the
structural elements. The entire structural set-up of the area, therefore, has been
worked out on the sub-surface data obtained through boreholes. It shows that
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 8 of 81
the Amadand Open Cast Block is located in the central part of the broad
basinal structure in the Amadand sub-basin intervening Jamuna & Kotma and
Jhagrakhand sub-basin and the same is presented in the form of Geological Map
(Plate-II).
4.3.5 STRIKE AND DIP
In the southern part of the block the strike is roughly E-W with 1o-2o northerly dip.
In the north-eastern part of the block the strike is roughly NW-SE with 2o-4o
south westerly dip. In the north eastern part of the block the strike is roughly E-
W with 1o to 3o southerly dip. In the western part of the block the dip of the strata
is less than a degree to almost flat. The overall structure may be attributed to the
depositional rolling nature of basin configuration.
4.3.6 PATTERN OF FAULT
The considered area is devoid of any fault. Earlier while preparing Amadand
Opencast area report, faults were interpreted but in due course after receipt of
more data of boreholes the possibility of faults was ruled out.
4.3.7 INTRUSIVES
Dolerite has been intersected in borehole no AMD-8 at the depths of 168.60m &
172.50m, located in the northern part of the block. From intersection it has been
surmised that the intrusive body has a discordant relation with the host rock. The
magnetic survey conducted in the area has confirmed the above postulate and
has delineated a single E-W trending, 24m-60m thick dyke. From the magnetic
intensity data, the dyke has been inferred to occur at a shallow depth in the
northern part of the block. Either the dyke occurs at a considerable depth or it is
highly weathered near the surface. No other dolerite body has been picked up in
the magnetic survey scanning in the balance part of the area.

4.4 DESCRIPTION OF INDIVIDUAL COAL SEAMS 4.4.1 SEAM-L6
Seam L6 is the top most from the surface within the Barakar Formation.
No splitting in this seam is observed in the block area.
This seam is intersected in 22 boreholes restricted in the central part of the block
area. The thickness range varies between 0.09m to 1.37m with more than 0.50m
thickness in 12 boreholes. The average thickness is 0.62m. Minimum parting in
respect of Seam L5, down below is 4.11m (CMAD-340) whereas the maximum
parting is 11.56 m (CMAD-271).
As the seam is having low thickness, not covering the considerable area in the
block and paucity of analytical data, Seam L6 is not considered for reserve
estimation as well as for structural interpretation.
4.4.2 SEAM-L5
This seam is second from the surface. This Seam is intersected in 58 boreholes.
The minimum thickness of 0.05m is observed in borehole No.CMAD-15 and
maximum thickness of 0.88m is observed in borehole No.CMAD-36. The seam is
having more than 0.50m thickness in 10 boreholes only. Though the Seam L5 is
more persistent than Seam L6, the workable area is distributed in patches. The
band-by-band analysis and proximate analysis are available for seven and four
boreholes respectively .The seam is not considered for reserve estimation.

C. STRATIGRAPHIC POSITION
Seam-UK Top being the top most split of Seam Upper Kotma is the third from
surface within the Barakar Formation.
D. PARTING In the block area this is the topmost workable coal seam. The seam occurs at a
minimum depth of 10.15m (CMAD-152, 332, 339) from the surface in the north
eastern and south western parts of the block and at a maximum depth of 28.40m
(CMAD-63) in the south central part of the block.
The parting between UKT & UKB seams predominantly consists of arenaceous
facies represented by sandstone. Since coal seams UKT & UKB are merged at
places, parting between them ranges between 0.00m to 5.36m (CMAD-343).
E. THICKNESS
It is observed that the minimum thickness of 0.30m is intersected in borehole
No.CMAD-63 and maximum thickness of 2.80m is intersected in borehole
No.CMAD-62. The average thickness of seam is 1.65m. Since Seam UKT is
having workable thickness in patches in major part of the block area, it is
described in detail and also considered for assessment of availability of coal
reserves.
F. SPLITTING
This seam does not show splitting in the block area.
G. OUTCROP/INCROP
The seam incrops to represent a broad basinal structure with its E-W longer axis
alongwith corresponding centripetal dip. The position of incrop is below the
weathered mantle.
H. ROOF & FLOOR
The immediate roof of Seam-UKT consists predominantly of coarse grained
sandstone, at places it is clay and sandy soil also. The immediate floor consists
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 11 of 81
of predominantly sandstone and sandy shale. At places, occasionally fine
grained to medium grained sandstone and carbonaceous shale are also found.

D. PARTING
In the block area seam occurs at a minimum depth of 3.05m (CMAD-523) from
surface in the western part of the block and maximum at a depth of 37.35m
(CMAD-35) also in the western part of the block.
The parting between Seam UK and Seam L4 predominantly consists of
arenaceous facies represented by sandstone. The parting between Seam UK
and Seam L4 ranges between 8.74m (CMAD-8) and 28.65M (CMAD-12) in the
eastern part of the block.
E. THICKNESS
It is observed that the coal seam thickness ranges between 0.45m (CMAD-51)
and 6.87m (CMAD-325). The seam exhibits a general reduction in its thickness
from east to west. The seam deteriorates into clay and carbonaceous shale in 22
and 2 boreholes respectively.
F. SPLITTING
The seam shows splitting into two seams (UKT & UKB) at various places, mostly
near incrop region. The splitting is due to development of parting ranging from
1.03m to 5.36m.
G. OUTCROP/INCROP
The seam’s incrop is in elliptical fashion in conformity to the basinal configuration
of the deposits. In the incrop regions, the seam in general has been observed to
deteriorate into clay in 22 boreholes and into carbonaceous shale in 2 boreholes.
The incrop shown is generally below the weathered mantle except near borehole
nos. AMD-05, CMAD-72, 80, 101, 172, 192, 282, 283 & 328 in which seam has
deteriorated and occurrence is within weathered zone. The incrop is shown upto
the borehole to avoid the confusion of up dip position of boreholes
H. ROOF & FLOOR
The immediate roof is generally sandy soil or clay. The floor of seam consists of
mainly sandstone.
I. DIRT BANDS
This seam contains impersistent dirt band. The lithology of dirt band is either
carbonaceous shale or shale. In the northern and central part of the area dirt
band is closer to the roof whereas in the southern part of the area it is located
closer to the seam floor.

C. STRATIGRAPHIC POSITION
This is the eighth workable seam and tenth from the surface within the Barakar
Formation in the block.
D. SPLITTING This seam is the split of MKC seam. The splitting is observed in southern,
eastern and north western parts of the block. In addition splitting is also
observed in patches. The seam itself does not further split in the block
E. PARTING
The seam occurs at a minimum depth of 17.98m (CMAD-88) from the surface in
the south eastern part and at a maximum depth of 87.15m (CMAD-39) from the
surface also in the north eastern part of the block.
The parting between MKT and MKB predominantly consists of arenaceous
facies. It is also carbonaceous shale, sandy shale occasionally. The parting
between aforesaid seams ranges between 0.94m (CMAD-91) and 16.23m
(AMD-2). It is generally observed that the parting between MKT & MKB seams
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 33 of 81
increases from west to east in the northern part. In borehole no CMAD-91,
parting between MKT & MKB is 0.94m and the seam is taken as split because
MKT is carbonaceous shale and its merger with seam MKB will deteriorate the
quality of the seam MKC.
F. THICKNESS
It is observed that minimum thickness of 0.04m is found in borehole No.AMD-15
and maximum thickness of 3.44m in borehole No.CMAD-273. The seam is
deteriorated into carbonaceous shale in 21 boreholes.
The seam is described in detail and also considered for assessment of
availability of coal reserves.
G. OUTCROP/INCROP
The seam incrops along the southern part of the block area. The position of
incrop is below the weathered mantle.
H. ROOF & FLOOR
The immediate roof and floor are predominantly coarse to medium grained
sandstone. At place carbonaceous shale is also at roof and floor. I. DIRT BANDS
The seam is having 1 to 3 dirt bands of both combustible and non-combustible
nature in seam in a few boreholes. However, in maximum boreholes seam is
devoid of dirt band.

The seam occurs at a minimum depth of 111.85m (CMAD-112) from the surface
in the southern part and at a maximum depth of 150.26m (CMAD-340) from the
surface also in the northwestern part of the block.
The parting between LKIIT and LKIIB seams predominantly consists of
arenaceous facies. The parting between aforesaid seams ranges between
1.05m (CMAD-270) and 4.21m (CMAD-54).
F. THICKNESS
It is observed that minimum thickness of 0.10m is found in borehole No.AMD-23
and maximum thickness of 2.68m is found in borehole No.CMAD-53. The
average thickness is 1.01m. The seam is deteriorated into carbonaceous shale
in one borehole CMAD-95.
The seam is described in detail and also considered for assessment of
availability of coal reserves.
G. OUTCROP/INCROP
The seam does not incrop in the block.
H. ROOF & FLOOR
The immediate roof and floor consists of coarse to medium grained sandstone.
Sometimes carbonaceous shale is also observed as roof and floor.
I. DIRT BANDS
The seam is having 1 to 2 dirt bands of both combustible and non-combustible
nature in seam in a few boreholes. However, in maximum boreholes seam is
devoid of dirt bands and no dirt band has been found less than 0.10m thickness
in any borehole.

4.5.2 Hydro-geological details:
Surface water:
Regionally, the Son River and its tributaries mainly control the drainage system
in the area. Kewai River, a major tributary of Son River flowing close to the
western boundary of the mine, in a north east to south west direction, is the
master drainage of the study area.
The block area is traversed by a small first order stream Banki Nala in the south-
west. Bhirwa Nala is flowing along the south eastern part of the project. Both
Banki Nala and Bhirwa nala is flowing towards south west direction and finally
they merge and discharge into Son River as Bhirwa nala.
Another important river close to the eastern boundary of the mine is Jhiria Nala
which is flowing in the North-east to East direction and finally merges with
Kulhariya Nala. Kulhariya nala is draining the north eastern part of the study
area. It is flowing form north to east and finally discharge into Hasdeo River.
The other streams which drain the buffer zone are Hendri Nala in north,
Bukbuka Nala, Bathi Dhar, Khari and Jhimar Dhar in east, Neori nala and
Keraha Dhar in south east. The drainage pattern in the area is mostly dendritic in
nature.
Groundwater:
The formations within the study area are Gondwanas and Talchirs. Major portion
of the area is occupied by Gondwanas and the rest by Talchirs. The project area,
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 64 of 81
situated on Barakar sand stone formation, comprises soil cover, weathered
mantle and sand stone of different grain sizes with shale beds and coal seams.
The weathered mantle and sand stone beds are saturated, and behave as
aquifers whereas the shale beds and coal seams as aquicludes. Due to
stratification and with the presence of aquicludes (shale/coal), a multi-aquifer
system is developed.
Eleven coal seams developed in the block and all the seams are selected for
opencast mining. The seams are centrally dipping and the gradient of the seams
area 1 in 30.
The alluvium formation and weathered Barakar formation comprising mainly of
loosely cemented and poorly consolidated grey coloured medium to coarse
grained sandstone lying above the Upper Kotma (Top) & Upper Kotma Combine
coal seams with a thickness varying from 20.0 m to 40.0 m behave as
unconfined aquifer. This unconfined aquifer is potential and prolific. The lower
formations, consisting of compact and fine to medium grained sandstone with
occasional sandy shale, carbonaceous shale and shale intercalation, with
secondary porosity, behave as semi-confined to confine in nature.
The general hydro-geological units developed in the Amadand block area are as
follows:

Aquifer Parameters
No detailed hydrogeological investigation has been carried out in the present
mine block. However, hydrogeological investigations were carried out by
CGWB & CMPDI in Jamuna coalfield, where the mine is situated, under S&T
project," Studies on Groundwater Flow into Coal Mines." The aquifer parameters
for the formation lying above the working seam (i.e. multi-aquifer) were reported
as:
Transmissivity (T) : 175 m2/day
Permeability (k) : 5 m/day
Storage coefficient : 5.0 x 10-4
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI

So also, detailed hydrogeological investigations were carried out at Bartarai UG
project just adjacent to Amadand OC Project, located in Jamuna-Kotma Area,
the aquifer parameters for lower aquifer were evaluated by SECL and reported
the permeability as 0.25 m/day.

Fig. (b)
The pre and post-monsoon water levels of Khodri station show decreasing
trends whereas the pre monsoon water level trend at Payari shows increasing
trend and post-monsoon water level trends at Payari station show marginal
decline. This upward trend may be attributed to the water conservation and
utilization of surface water for irrigation use in the area. The decline in pre and
post-monsoon water level at Khodri village may be attributed to increase in
ground water utilization due to increase in the local population and the irrigation
draft and .decrease in rainfall.
Groundwater Stage of Development:
Except for coal mining, no major industrial development activity is located in the
area. Due to dominant forest area and backwardness the groundwater
development in the area is very insignificant. As per CGWB, NCC Region, Raipur,
the total annual replenishable ground water resource in the Anuppur Development
Block, Shahdol district (where Amadand Block exists), was assessed as 68.20
M.Cum. It was also reported that the ground water development in the block is as
1.99 % and falls within category "Safe". As such, the entire Madhya Pradesh &
Chhattisgarh States are covered under the category “Safe”.
Water Quality:
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 70 of 81
Under routine environmental monitoring, the surface, groundwater and mine
water quality, for all the operating mines in the area, have been monitored and
found to be well within the permissible limits of stipulated standards. Mine water
and other effluents have been treated before disposal and usage.
Mine Drainage:
In sedimentary rocks, due to stratification, the horizontal permeability (KH) is
many folds higher than the vertical permeability (KV). The permeable beds act as
individual hydrogeological units and develop a multi-aquifer system. Thereby, the
groundwater velocity / flow along the bedding plane are higher than across the
plane. The opencast mine can be simulated as a large diameter well and the
inflows are contributed mainly from the saturated formation lying above. Thus,
the mine inflow is directly proportional to the aquifer and mine parameters.
In the initial stage the mine inflow is in proportion to the rate of mine expansion.
With the presence of low permeable formations, the inflow is significantly small.
In due course of mining, due to partial de-saturation of the aquifer, the inflow
reduces and gets stabilized.
Presently, in Amadand Opencast mine, the permeable formations lying above
the deepest working seam (Lower Kotma II Bottom) are mainly composed of
sandstone with occasional intercalation of shale, sandstone and sandy shale.
The present depth of workings is about 35m against an ultimate planned depth
of 150m. The present mine discharge during dry period is estimated as 3,928
m3/d, which can be considered as the ground water inflow into the mine.
Disposal of Mine water:
To meet the safety of the mine and create good working conditions, it is necessary
to discharge the mine water collection onto surface. To collect the present mine
water inflow from the operating two quarries (Departmental Patch and Contractual
Patch), three sumps with a total holding capacity of about 65,000 cum. (i.e.
Departmental Patch = 24,000 + 9,000 cum & Contractual Patch = 32,000 cum) are
existing and equipped with suitable sumps. The main sump floor RL in
Departmental Patch is 510.00 m. whereas, the sump floor RL in Contractual Patch
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 71 of 81
is 505.00 m. As the mine is in the starting phase and because of lack of adequate
storage space within active mine area, so, most of the monsoon water collection
has been discharged on the surface. As such the entire industrial water demand
has been met from mine water only.
To handle the inflow 9 pumps (3 Nos. @ 1000 gpm, 6 Nos. @ 700 gpm), including
standby, with a total discharge capacity of about 7,200 gpm (545 LPs) are
operating in both the working quarries. As such, the monsoon water collection has
been stored in the sumps and only the overflow of these sumps has been
discharged.
The present mine water discharge varies from about 21,210m3/day during peak
monsoon period to about 3,928 m3/day in lean period. Thereby, the average
pumping (120 days rainy period + 245 days lean period) from Amadand OCP is
9,610m3/day. This discharge includes both rainwater collection and groundwater
seepage into the mine.

This stored water has been effectively utilized for industrial purposes within mine
premises, such as, mine operation, dust suppression, CHP, workshop, greenbelt
development and fight fighting uses. Most of the mine water has been discharged
after sufficient settling time. Thereby, the discharged water is almost clean with
very less TSS load. The mine water after settling in mine sumps has been
discharged to various utility points and excess water / overflow has been
discharged into the adjacent ponds and irrigation land for local users.
During monsoon, part of the mine water has been discharged on down dip for
irrigation use, the overflow of which will ultimately reach the adjacent Banki Nala
flowing in the southern part of the mine. Because of clean water in sufficient
quantity is available for local irrigation, the crops in these villages are protected.

4.6 GEOLOGICAL RESERVES
4.6.1 BRIEF METHODOLOGY FOR RESERVE ESTIMATION
Estimation of quarriable reserves has been made on the following considerations:
(i) The effective thickness of the seams considered for quarriable reserves
includes all combustible and non-combustible bands upto 0.10m,
(ii) All bands of more than 0.10m thickness irrespective of their lithology have been
excluded from seam thickness for arriving at effective seam thickness in the
case of quarriable proposition.
(iii) All the unworkable coal bands/coal sections occurring above/below the
delineated roof/floor of the seam sections and also those occurring within the
seam partings have been added to the overburden.
(iv) The cumulative thickness of all bands excluded from the seam thickness has
been added to the seam burden.
(v) For estimation of quarriable reserves, thickness ranges of 0.50 to 0.90m, 0.90
to 1.20m, 1.20 to 1.50m, 1.50 to 2.00m, 2.00 to 2.5m and 2.5m to 3.00m and so
on, have been considered.
(vi) The minimum thickness considered for reserve estimation has been taken as
0.50m as desired by Mine Planners.
(vii) The influence area around the borehole in which seam has deteriorated to
carb.shale, shale or clay has not been considered for reserve estimation.
(viii) Thickness and quality values of seams in boreholes have not been considered
wherever values are not in conformity of surrounding boreholes. For instance,
in case of MKT Seam values of boreholes AMD-15, CMAD-62, 115, 121, 127
and 243 and for Seam L-1, values of borehole CMAD-64 has not been
considered
CATEGORAIZATION OF RESERVES
The entire reserves of fifteen coal seams viz. UKT, UKB, L4, L3T, L3B, L3,
MKT, MKB, MKC, LKI, L1, LKIIT, LKIIB & LKII, have been placed under 'Proved'
category as per Indian Standard Procedure.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 4 / 73 of 81
Although, forest area has been shown to occur nearly at southern and in the
north-eastern part of the block, where drilling could not be possible, there is
hardly any difference between two boreholes of around 50-100m after
considering the area of influence of 200m to satisfy the norms of indicated
reserves. Therefore, all the reserves are considered to be covered under
“Proved” category.
To obtain net in-situ geological reserves, a total deduction of 10% has been
made from the estimated gross reserves to compensate for loss on account of
faults and other unforeseen geological conditions.
METHODOLOGY
The volume of coal reserves has been calculated by volumetric method.
Volume (mm3) = Area (in sq.km.) x thickness (m) considered.
The seam thickness and grade between various borehole points have been
extrapolated and depicted by drawing isochores & isogrades.
SPECIFIC GRAVITY
For the purpose of converting volume of coal into tonnage, specific gravity of
1.40, 1.42, 1.47, 1.52, 1.58, 1.67 and 1.70 has been assumed for grades A, B,
C, D, E, F and G respectively.
COMPUTATION OF COAL RESERVES
The isochore method has been used for estimation of reserves. The following
formula has been used for this purpose:
R= A x Th.x Sp.Gr.
Where R= Gross reserves in million tonnes
A=Area in sq.km.
Th.= Thickness in meter
Sp. gr.= Specific gravity
As stated earlier, a 10% deduction from the gross reserves has been made to
arrive at the net in situ ‘proved’ reserves available in the block.

METHODOLOGY OF OVERBURDEN ESTIMATION
The following procedure has been adopted for the estimation of overburden in
Amadand OC Block.
A total excavation (iso depth) plan has been prepared at 5m interval after
intersecting the surface contour with the floor contour of Seam LKIIB & LKII (the
lower most workable coal seam) to arrive at the total depth of excavation.
Isochores on I10 basis of the total coal of the seams considered for opencast
mining viz. Seams UKT, UKB,UK, L4,L3T, L3B, L3,MKT, MKB, MKC, LKI,
L1,LKIIT,LKIIB & LKII were intersected with each other to arrive at the
thickness of the total coal present. Isochores of the total coal, thus drawn, in the
respective area of occurrence of the seam(s), were intersected with the iso-
depth lines to arrive at the thickness and volume of total overburden in the
area. Different Coal: OB cut-off ratio lines were accordingly arrived at. The iso-
depth lines at 5m interval and the coal to OB cut-off ratio lines were transferred
onto the seam folio plans.
- The volume of overburden has been estimated by the volumetric method, i.e.
Volume (mm3) = Area (sq. km.) x thickness (m) considered.
- The volume of overburden has been estimated, depth wise and Coal: OB cut-
off ratio-wise.
- To arrive at stripping ratio, the total volume of overburden within the block area
has been divided by the corresponding coal reserves.

DEPTH OF EXCAVATION
The maximum depth of excavation would be about 152.54m (CMAD-340) which
is found locally in borehole no. CMAD-340 up to the floor of Seam LKIIB due to
topographic high, surface RL of borehole CMAD-340 is 541.05m in the north
western part of the block. However, The coal reserves for all the coal seams viz.
UKT, UKB, UK, L4, L3T, L3B, L3, MKT, MKB, MKC, LKI, L1, LKIIT, LKIIB & LKII
are available within 170.00m average depth of excavation.
4.6.2 DESCRIPTION OF RESERVES
SUMMARY
A total of 160.57 Mt of proved reserves of coal have been estimated in Amadand
OC Block.
These includes 68.27 Mt (42.52%) superior grade coal of (A, B, C) grade and
90.30 Mt (57.48%) coal of inferior grade (D, E, F,G).
Out of the total Net Proved Reserves of 160.57 Mt of coal 6.19% is of ‘A’ Grade,
11.45% is of ‘B’ Grade and the bulk of the reserves, i.e. 24.87% falls under ‘C’
Grade, 23.40% is of ‘D’ Grade, 9.53% is of ‘E’ Grade, 11.53% is of ‘F’ Grade
and 13.03% in ‘G’ Grade. The quarriable reserves falling in the total proved
category are within 170.00m depth. Since the reserves are to be extracted by
opencast method, all the coal seams reserves have been assessed for coal
seams having thickness more than 0.50m (>0.50m), as desired by mine
planners.

4.7 RECOMMENDATION 1. The reserves estimated and geological interpretation made could be regarded as
fairly accurate within the limits of available data. A few boreholes along
proposed entry alignment are recommended to ascertain the point of disposition
of the coal seams and incrops.
2. Although not a single fault has been delineated in the block, but possibility of
some minor slips of small magnitude may not be ruled out.
3. Though the incrops have been proved on the basis of boreholes drilled, few
boreholes may be taken up, if suggested by the Planners in view of the
variable/rolling nature of the dips.

CHAPTER - V
MINE BOUNDARY, RESERVES AND MINE LIFE
5.1 INTRODUCTION
The Amadand Opencast Block is located in the eastern part of south
Sohagpur Coalfield and is flanked by working mines of Hasdeo and Jamuna
& Kotma areas of SECL to the east and west respectively.
Project Report for Amadand OC (1.15 Mty) was prepared with an average
stripping ratio of 4.58 cum/t considering only upper seam i.e UK seam and
submitted to SECL in August 2003 and approved in Sept 2003. During
preparation of Amadand OC (1.15 Mty) report, lower seams e.g. MK (Top)
and MK (Bottom) and LK-II were also considered for extraction by opencast
method. But, due to high stripping ratio, the quarriability of lower seam were
not feasible for departmental option. So seams below UK seam were not
considered in the 1.15 Mty PR.
Latter on, decisions was taken to extract coal from bottom seams.
Accordingly, Revised Geological Report have been prepared, considering
workable coal seams upto bottom most LK-II seam which has not taken into
account for opencast mining earlier. In the area under consideration seams,
L-6, L-5, UK (Top), UK (Bottom), UK, L-4, L-3(Top), L-3 (Bottom), L-3, MK
(Top), MK (Bottom), MKC, L-2, LK-I, L-1, LK-II (Top), LK-II (Bottom) & LK-II
have encountered in descending order.
The present report is formulated considering all the seams upto bottom
most LK-II seam for mining with outsourcing option.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 5 / 2 of 5
5.2 PIT FORMULATION STRATEGY
It is proposed to extract all the seams UK (Top), UK (Bottom), UK, L-4, L-
3(Top), L-3 (Bottom), L-3, MK (Top), MK (Bottom), MKC, L-2, LK-I, L-1, LK-
II (Top), LK-II (Bottom) & LK-II as they can be mined techno-economically
by opencast method. Quarry floor has been proposed on the floor of Seam-
LK-II. Access trench & Haul Road is proposed to touch seam LK-II at floor
RL of 420m. Haul roads have been planned at a maximum gradient of 1 in
16, the width of the haul road has been kept as 30 m for two way dumpers
movement.
This PR has been formulated mainly considering the following details:-
1. Increased demand of superior grade coal from CIC Coalfields.
2. Sufficient mineable reserves
3. Workable strike and dip length
5.3 MINE BOUNDARIES
The quarriable area for the opencast mining is shown on Plate No.3 &
Figure-5.1. One quarry on floor of Seam LK-II has been planned. The
boundary of quarry has been fixed as follows: -
North : Incrop of Upper Kotma Seam.
Reason- Beyond UK seam incrop the stripping ratio is high
(more than 20).
South : Incrop of Upper Kotma Seam.
Reason- Beyond UK seam incrop the stripping ratio is
high (more than 20).
East : A line keeping 100 m barrier from boundary of Amadand
Village.
Reason-. The major state highway Pendra to Manendragarh
is passing along the middle of the Amadand Village. Two UG
mines namely, Amadand UG & Bartarai UG are situated on
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 5 / 3 of 5
other side of the Pendra-Manendragarh state highway road
and area of these mines are not included within quarry
boundary of this 4.0 Mty RPR Report.
West : Incrop of Upper Kotma Seam
Reason- Beyond UK seam incrop the stripping ratio is high
(more than 20).
Khodri Block has not been included in the proposed mine area. The
incrop of coal seams also exists in the northern side of Khodri Block.
Thus, Khodri Block can be extracted from the northern side of the block as
a separate mine.
5.4 MINEABLE RESERVES
As on 01.04.2015, the total mineable reserves within the quarries have
been estimated as 70.46 Mt with a corresponding OB volume of 764.40
Mcum. The already extracted coal & OB removal has been deducted to
get the balance remaining coal & OB quantity. While, calculating mineable
reserves, a geological loss of 10% and a mining loss of 10% have been
considered. The estimation of mineable reserves is based on a minimum
mineable thickness of 0.5 m. The mineable reserves have been estimated
by iso-chore method from the seam extent plan of individual seams.
Similarly, OB has been estimated based on iso-parting and Top OB plan.
The plan showing seam extent of individual seams under consideration
are given at Plate No. 6 to 16. The top OB and the iso-parting plan
between seams under consideration are given at Plate No. 17 to 27.
5.5 TARGET OUTPUT & MINE LIFE
The mine is proposed for peak coal production of 4.00 Mty and peak OB
removal is of 52.54 Mty.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 5 / 4 of 5
Mine Life The mine life for nominal production is 19 years. The break-up is as under:
Production build-up period - 3 years
Production period - 15 years
Tapering period - 1 year
Total period - 19 years
5.6 FUTURE EXPANSION POTENTIAL It is proposed to extract upto the bottom most seam LK-II of the area.
Thus, mine does not have the scope to expand further in vertical direction.
In northern side, Khodri Block has not been included in the proposed mine
area. There is high stripping ratio zone(more than 20) between present
quarry boundary and Khodri block boundary. The incrop of coal seams
also exists in the northern side of Khodri Block. Thus, Khodri Block can be
extracted from the northern side of the block as a separate mine. In
western and southern side, beyond UK seam incrop, the stripping ratio
is high (more than 20). Thus, mine does not have the scope to expand
further under the present condition to north, south and west directions.
In eastern side, the quarry boundary fixed along a line keeping 100 m
barrier from boundary of Amadand Village. The state highway Pendra to
Manendragarh is passing along the middle of the Amadand Village. Two
UG mines namely, Amadand UG & Bartarai UG are situated on other side
of the Pendra-Manendragarh state highway road and area of these mines
are not included within quarry boundary of this 4.0 Mty RPR Report. In
future, if diversion of major state highway Pendra to Manendragarh can be
undertaken, decisions taken to extract UG property by opencast method
and shifting of Amadand village can be undertaken, in that case the
Amadand OC can be expanded in the east direction. Quarry planning and
dump plan has been proposed accordingly such that quarry can be
expanded in east directions in future.

METHOD OF MINING
6.1 GENERAL The PR has been formulated to win coal by Surface Miner with FEL and
coal body trucks & OB by Shovel Dumper combination.
In Outsourcing Option both winning of coal and extraction of OBR will be
done through outsourced HEMM. Transport of coal from face to railway
siding will be done by inpit belt conveyor & surface belt conveyor.
It is proposed that mine will be operated for 330 days in a year. In a day,
there will be 3 shifts and each shift is of 8 hours.
6.2 GEO-MINING CHARACTERISTICS
6.2.1 Seam Gradient - Variation, average gradient of quarry floor 1 in 30.
6.2.2 Geological Disturbances -
Only one normal fault F1F1, trending E-W and having a maximum throw of
80m, have been deciphered in the area at the northern boundary of block.
Within mine area no fault exists. However, the occurrence of faults of
small lesser magnitude cannot be entirely ruled out in the area.
6.2.3 Presence of In-seam band seam-wise The in-seam of all the seams is composed mainly of carbshale, shale,
sandy shale and sandstone.
6.2.4 Details of sequence of coal seam and parting
The sequence of coal seams with their thickness and parting range,
average grade & UHV range, Mineable coal and volume of OB within the
proposed mine area are as shown in table below:-

.CHOICE OF TECHNOLOGY
Surface miner has been proposed for extraction of coal. The salient
feature of the mining system is as follows: -
(i) Height & width of the benches in OB will depend upon the size
of the leased equipment. However, for Surface Miner height
restriction is not there. The provision of Coal Mine Regulation
and related circulars shall be strictly followed for designing
bench parameters in coal and OB.
(ii) Dump bench height - 30m (Internal dump has 7 benches and
total dump height 230 m from quarry floor & 90m from surface,
External dump height is 120m from surface).
(iii) Bench Slope
Coal / OB - 700
Spoil - 370
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 6 / 6 of 9
Considering the average mine floor gradient of about 1 in 30, the coal
benches are proposed parallel to seam floor and self-draining. The mining
system is shown at Plate No. 6.
DRILLING & BLASTING
Pattern for drilling of blast holes will depend upon the height of the bench
and may design as follows: -
Height of Bench = H
Burden (B) ~ H/2
Spacing (S) ~ B*1.25
The suggested drilling pattern is for average mining conditions. These
may be suitably modified during actual mining operations as per the site
conditions.
HAUL ROAD
Haul roads have been planned at a maximum gradient of 1 in 16, the
width of the haul road has been kept as 30 m for two way dumpers
transport. Two batter road of 50m width will be maintained along UK seam
& MK seam for laying side road and inpit belt conveyor. (details given in
chapter 11)
6.5 EQUIPMENT SELECTION
The PR has been formulated to win coal by Surface Miner with FEL and
coal body trucks & OB by Shovel Dumper combination.
In Outsourcing Option both winning of coal and extraction of OBR will be
done through outsourced HEMM. Few auxiliary HEMM has been given for
mine development and reclamation related work. Transport of coal from
face to railway siding will be done by inpit belt conveyor & surface belt
conveyor. To handle the larger OB quantity optimum no. of equipment with
required capacity is proposed be used. Minimum 10 cum Shovels with
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 6 / 7 of 9
100T rear dumpers will be used for OBR by outsourcing agency. For thin
partings, smaller backhoe may be used.
As depth of OB increases the annual OB removal will also increased. To
handle the larger OB quantity optimum no. of equipment with required
capacity is proposed be used. Due to flexibility of operation, Shovel-
Dumper combination will be suitable for OB removal for working multiple
seams and partings.
The property is free from any major geological disturbances. Average
gradient of quarry floor is 1 in 30. The average strike length of the quarry
is 3.0 km. Thus, sufficient face length will be available for optimum
efficiency of surface miner.
The bottom most seams LK-2 have been splitted into LK-2 Top and LK-2
Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m.
Above LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to
0.90m. Parting thickness between Seam LK-2 and L-1 varies 6 m to 18 m.
Thus, dragline horizon changing will be required for operation of dragline
and dragline productivity will be less. Besides, the bottom coal bench may
be diluted as low thickness coal seam may be mixed with OB during
dragline operation. Considering multi-seam working and wide variation of
parting OB, dragline has not been proposed in this Project Report.
6.6 MINING SYSTEM & SYSTEM PARAMETERS
Surface miner has been proposed for extraction of coal.
The salient features of mining system are as follows:-
i) Height of bench in OB will depend on the size of equipment.
Coal bench height will depend on the thickness of the coal seams.
The provision of coal mine regulations and related circulars shall be
strictly followed for designing bench parameters in coal and OB.
ii) Average Seam gradient – 1 in 30.
iii) Total dump height – Internal dump height is 230 m from quarry floor
but it will be 90m from surface. External dump height is 120m from
surface.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 6 / 8 of 9
iv) Bench slope –
Coal/OB - 70 degree
Spoil - 37 degree
Keeping the geo-mining characteristics of the deposit, in view, optimum
number of equipment with optimum capacity is proposed be used.
6.7 SCOPE OF WORK PROPOSED TO BE OUTSOURCED i) Drilling
The external agency will prepare the site and carry out blast hole
drilling as per the pattern decided by the project authorities according
to strata conditions and stipulations of DGMS

CHAPTER-VII
MINING & DUMPING STRATEGY
7.1 CONSTRAINTS ON MINE DEVELOPMENT (i) The nearest railway siding is Govinda Railway siding which is
situated at a distance of about 5.0Km from the mine. The railway
line extension from Bhaiyatola station is required to connect the
upcoming Amadand siding.
(ii) Rehabilitation & resettlement of four villages namely Nimha,
Timkitola-Amadand, Harratola-Kuhka and Majholi are involved in
the project. Acquisition of land alongwith R&R of PAP is a critical
activity and should be taken up on top priority.
7.2 MINING STRATEGY / MINING SEQUENCE
At present Amadand OC is a running mine with a peak coal production of
1.15Mty and it is already extracting coal from UK seam.
It is proposed to expose MK seam in the 2nd year of mine operation by
grading properly the access trench and making its width 30 m wide and
gradient at 1 in 16. Then sufficient area to be exposed in the MK seam
floor. In the 3rd year of mine operation, the access trench is to be graded
at 1 in 16 to touch the mine floor at LKII seam of about 405 m R.L.
The quarry floor is developed in such a manner so as to facilitate
the proper drainage of water towards the sump. This would also facilitate
extension of coal and OB bench for full development of mine. After
creation of sufficient decoaled area, internal backfilling of OB will be
started in the 5th year. The coal production will continue from the 1st year
of mine life and the target coal production of 4.00 Mty will be achieved in
the 5th year.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 2 of 8
Two batter road of 50m width will be maintained along eastern side
batter. One batter road along floor of UK seam will be used to place inpit
belt conveyor to carry coal from UK & L4 seam as thown in plate 3. Other
batter road along floor of MK seam will be used to place inpit belt
conveyor to carry coal from MK, L3 & LK1 seam. One another inclined
inpit belt conveyor will be placed upto floor of LKII seam to carry coal from
LKII & L1 seam. Finally, through inclined belt conveyor all the coal will be
transported to surface as shown in the plate-3. From pit top coal will be
transported to upcoming Amadand siding through surface belt conveyor.
.(details given in chapter 11)
For reducing the external dump area and healthy operation of mine, 2
plans i.e. final stage of mine excavation and final dump plan showing
backfilling, Plate No. 3 & 4 are enclosed. The life of mine will be 21 years.
7.3 DUMPING STRATEGY In the initial years i.e. upto 4th year, entire OB will go to the external
dumps. For project implementation and aquision of land for external
dump may take 3 to 4 years. During this period about 20 Mcum OB
will be dumped internally. Provision of rehandling of this internal dump
to external dump site has been considered in the project costing.
Internal dumping will start from the 5th year onwards. The parting OB in
case of older seams may be transported partly through central haul road,
while mining in the multi seam zone.
Initially, the soil/alluvium from top bench of OB will be stacked and stored
separately. The spoil dump benches in the internally backfilled OB will be
in the form of benches. With the sufficient advance of coal production
bench, the backfilled OB will be leveled with dozer..
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 3 of 8
Dumper/Tipper will transport soil/alluvium OB from the top OB bench and
will dump the soil directly on the leveled backfilled OB. The barrier
distance between internal dump and coal production bench will be 80 m to
have smooth functioning of machineries.
The slope stability study should be done. According to study report, the
dump design like dump bench height, total dump height & slope etc.
should be modified to avoid dump failure. In addition to that proper
precautions should be taken to avoid sliding of internal OB bench.
238.02 Mcum OB will be externally dumped outside quarry area from 1st
year to 10th year for which 356.50 Ha land will be required.
The northern boundary of Amadand OC block is along the Fault F1-F1
having throw of 20m to 80m. On the other side of Fault F1-F1 Khodri Block
exists where UK seam occurs at a minimum depth of about 21m. So
external dump has not proposed in the Khodri Block.
External dump has been made near southern boundary as shown in Plate
No.4. The break-up of OB quantity to be accommodated in various dumps
is as follows:-
Dump OB accommodated in Mcum 1. Internal dump 526.38 2. External dump outside Quarry area 238.02
Top soil will be removed and stored separately. This soil will be directly
spread over the leveled graded backfilled spoil for reclamation of the
quarried out land. Possibility of external dump within quarry boundary and
rehandling back into the quarry has been examined. Considering the high
quantity of external OB placing of external dump within quarry boundary
will not to be feasible. So placing of external dump proposed outside the
quarry area.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 4 of 8
Amadand OC can be expanded in the east direction. Quarry planning
and dump plan has been proposed accordingly such that quarry can be
expanded in east directions in future. At the end of quarry life, if required,
the void left will be filled to reduce the depth of void to 60m. Necessary
filling of the void will be done from mine closure cost. Initially the height of
internal dump is 90m from surface. After fifteenth year of mine life the
internal dump height will be kept upto surface level. Thus about 228.18 Ha
land will be levelled to surface level and can be utilized for agricultural
purposes.

7.6 TOP SOIL MANAGEMENT
1.0 INTRODUCTION
The topsoil at Amadand block comprises of rich humus with minerals and
nutrients. Proper handling and management is necessary for future
vegetation growth in the mine reclaimed area. The thickness of the top soil
varies between 25 cm to 35 cm.
1.1 Objectives of the Soil Stripping management plan
The objectives of Top Soil Management are to:
Maintain a topsoil balance that achieves rehabilitation objectives during
the life of Mine.
Ensure effective topsoil removal techniques are employed to maximise
volumes of suitable topsoil removed and minimise wastage.
Maintain topsoil viability during stripping, spreading, and stockpiling,
through best practice technique and effective stockpile design and
treatment .
In accordance with the objective of providing sufficient stable soil material
for rehabilitation and to optimise soil recovery, the following strategies will
be adopted during the mining operation at Mahan opencast mines.
1.2 Stripping Prior to the commencement of stripping, areas will be cleared of
vegetation. Soil stripping will be undertaken by dozers and hydraulic backhoe
excavators to maximise the preservation of the quality of the soil. The HEMM
operators and supervisors should be trained and made aware for the same. This
will ensure that all suitable topdressing material resources are salvaged and that
the quality of the stripped top dressing material is not reduced through
contamination with unsuitable soils. Care will be taken during stripping,
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 6 of 8
stockpiling, and re-spreading to ensure that structural degradation of the soil is
avoided and that excessive compaction does not occur during stockpiling.
1.3 Stock piling
Where possible, topdressing material will be re-spread directly from
stripped areas onto areas being rehabilitated. Where this is not possible,
topdressing material will be stored in stockpiles.
Stock piles will be dumped at places where they would not be disturbed by
future mining. Sediment fences or other barriers can be used where
necessary to retain sediment.
The overall topography for the graded surface should be designed to
minimize the uncontrolled flow of runoff.
Dispersed sheet flow should be broken up by terraces or benches along
the slope that also follow topographic contours.
On a fine scale the ground surface can be roughened by the tracks of a
bulldozer perpendicular to the slope. Construction of stockpiles with a
“rough” surface condition will reduce erosion hazard, improve drainage
and promote revegetation.
1.4 Stockpile preservation
Stockpiling topsoil may result in disruption & loss of beneficial soil
microorganisms and nutritional values, hence needs the following amendments
during preservation:-
1) Re-vegetation of the stockpile will be done as scheduled below to protect the
soil from erosion, discourage weeds and maintain active populations of beneficial
soil microbes.
Temporary Seeding- To protect topsoil stockpiles by temporarily
seeding as soon as possible, within 30 days after the formation of
the stockpile.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 7 of 8
Permanent Vegetation- If stockpiles will not be used within 12
months they will be stabilized with permanent vegetation to control
erosion and weeds. Likely grass species for revegetating top soil
stock piles are green panic, Japanese millet (spring sowing), Oats
(winter sowing), Dryland Lucerne, Seaton park sub-clover.
Topsoil can be mixed with organic material or manufactured soil
amendments to improve the growing capability.
2) To the extent practicable, above ground vegetation, including tree litter
should be mixed or otherwise incorporated into the topsoil.
3) Soil amendments: Soil amendments should be applied before seeding or
planting. Common soil amendments used are biosolids, compost, manure, lime
and coal combustion byproducts.
Prior to the placement, the top 0.30 cm of stockpile material should be
mixed with the remainder of stockpile to ensure that living organisms are
distributed throughout the topsoil material at the time of final placement. In case,
the material has been stockpiled for over nine month period, use of
microorganisms inoculates may be necessary to re-establish microorganisms in
the topsoil material. The quantity should be 200 ml for one Heactare area in case
of Azatobactor and Rhizobium.
1.5 Site Preparation
Before spreading topsoil, establish erosion and sedimentation control
structures such as diversions, berms, dikes, waterways and sediment
basins.
Adjust grades and elevations for receipt of topsoil.
Roughening - Immediately prior to spreading the topsoil, loosen the
subgrade to ensure bonding of the topsoil and subsoil.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 7 / 8 of 8
Soil horizons will be replaced in the same order that they were removed.
Top soil will be uniformly distributed to pre-mining thickness. Topsoil will
not be spread while it is frozen or muddy .
The topsoil will be compacted to ensure good contact with the underlying
soil, but excessive compaction will be avoided, as it increases runoff and
inhibits seed germination. Light compaction with roller will be done where
turf is to be established.
On slopes and areas that will not be mowed, the surface will be left rough
after spreading topsoil.
1.6 Monitoring
Specific team / manpower is to be deployed for this most important step of
topsoil management. The team will monitor the area and quantum of top soil
management with the authorities of mine on quarterly basis and regularly monitor
the given points of significant importance:
Monitoring Erosion Control: This step is necessary during stock
piling as well as reclamation stage of topsoil management. Take corrective
measure in areas showing evidence of erosion, sedimentation or slope
failure. This is a serious problem, because erosion causes fertile farmland
to lose nutrients and water retention ability.
Regular monitoring of top soil management should be done until
vegetation is demonstrated to be successfully established.
Reseeding: Take appropriate measures to address evidence of
invasive species or poorly established vegetation. Reseeding should be
done, if germination is not uniform or poor.

CHAPTER - VIII
MINING SCHEDULE & EQUIPMENT PHASING
8.1 DESIGN CRITERIA
Transport of coal from face to railway siding will be done by inpit belt conveyor
& surface belt conveyor. The mine has been planned for 330 days with 3 shifts
working per day. Duration of shift hours will be eight.
Excavation category assumed
i) Coal - - III
ii) Alluvial OB - Cat.I/II : Assumed
iii) Hard OB - 50% cat.III + 50% cat.IV Insitu volume weight t/cum i) Coal - 1.52 t/cum ii) Overburden - 2.40 t / cum
8.2 ANNUAL PRODUCTIVITY OF HEMM
The PR has been formulated to win coal by Surface Miner & OB by Shovel
Dumper combination. For OB removal year wise lead has been estimated and
based on that average lead for OB removal is estimated to 3.0 Km.
Transport of coal from face to railway siding will be done by inpit belt
conveyor & surface belt conveyor. The Annual productivity of outsourced
HEMM will depends on the size of deployed HEMM.
8.3 EQUIPMENT SELECTION
The PR has been formulated to win coal by Surface Miner with FEL and coal
body trucks/dumpers & OB by Shovel Dumper combination. In Outsourcing
Option both winning of coal and extraction of OBR will be done through
outsourced HEMM. Due to flexibility of operation, Shovel-Dumper combination
will be suitable for OB removal for working multiple seams and partings. As
coal production increased, the annual OB removal will also increased. To
handle the larger OB quantity optimum no. of equipment with required capacity
is proposed be used. Minimum 10 cum Shovels with 100T rear dumpers will be
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 8 / 2 of 6
used for OBR by outsourcing agency. For thin partings, smaller backhoe may
be used.
The property is free from any major geological disturbances. Average gradient
of quarry floor is 1 in 30. The average strike length of the quarry is 3.0 km.
Thus, sufficient face length will be available for optimum efficiency of surface
miner.
The bottom most seams LK-2 have been splitted into LK-2 Top and LK-2
Bottom. Both of the splits have varying thickness from 0.7 m to 1.50m. Above
LK-2 Seam, Seam L-1 exists having seam thickness 0.70m to 0.90m. Parting
thickness between Seam LK-2 and L-1 varies 6 m to 18 m. Thus, dragline
horizon changing will be required for operation of dragline and dragline
productivity will be less. Besides, the bottom coal bench may be diluted as low
thickness coal seam may be mixed with OB during dragline operation. So
dragline has not been proposed in this Project Report.
8.4 EXISTING HEMM POPULATION
In Outsourcing Option both winning of coal and extraction of OBR will be done
through outsourced HEMM. Few auxiliary HEMM has been proposed for mine
development and reclamation related work. In outsourcing option, few existing
HEMM will be used as auxiliary HEMM for mine development and reclamation
related work and rest of HEMM will be transferred elsewhere.
8.5 DRILLING & BLASTING
OB will be loosened by drilling and blasting to facilitate their excavation. The
actual pattern for drilling and blasting will be decided after field trials. For
secondary blasting 10% of additional explosives will be required for OB. The
drilling will be done carefully to keep at least 1.0m to 1.5m OB parting above
coal seam to reduce contamination of coal with fragmented OB. Whenever
required Ripper will be used reduce contamination of coal with fragmented OB.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 8 / 3 of 6
SMS explosives should be used wherever possible. The pattern for drilling of
blast holes will depend upon the height of the bench and may be designed as
follows: -
Height of bench = H
Burden (B) - H/2
Spacing (S) - B*1.25
The suggested drilling pattern is for average mining conditions. These may
suitably be modified during actual mining operations as per the site conditions.
The explosives consumption has been envisaged as 0.30 - 0.35 kg/cum of
excavation.
The ground vibration due to blasting can be controlled by:-
i) Optimising the amount of explosives charged per delay,
ii) Optimising spacing and burden of blast holes,
iii) Optimising the amount of explosives charged per blast,
iv) Proper strata movement during blast by using suitable initiating sequence.
Since above parameters are site specific, the exact blasting pattern will be
designed by conducting field trials.
8.6 CALENDAR PROGRAMME OF EXCAVATION
The mine is proposed for peak coal production of 4.00 Mty and peak OB
removal is of 52.54 Mty. The total mineable reserves within the quarries have
been estimated as 70.46 Mt with a corresponding OB volume of 764.40 Mcum.
While, calculating mineable reserves, a geological loss of 10% and a mining
loss of 10% have been considered.
Production build-up period - 3 years
Production period - 15 years
Tapering period - 1 year
Total period - 19 years Considering the average width of quarry and annual advance of quarry floor,
the calendar programme has been prepared and given in the following table: -

CHAPTER - IX
COAL QUALITY 9.1 INTRODUCTION
On the basis of moisture and ash percentage different litho units are
defined as under: -
Coal : Ash + Moisture upto 40%. Shaly Coal : Ash + Moisture from 40% to 55%. Carbonaceous shale/
combustible dirt band : Ash + Moisture from 55% to 75%. Obvious dirt bands : Ash + Moisture more than 75%.
Initially, the band by band analysis of the coal cores were obtained and
subsequently special tests and the proximate analysis at 60% RH and
400C were advised for Bcs, I30, I10, I100 and Ip basis which are defined as
under: -
Bcs Sample: only coal and shaly coal. I30 Sample: including combustible bands upto a thickness of 30cm. This
type of analysis has been asked only for assessing under ground
reserves. Dirt bands upto 5 cm irrespective of lithology have been
included in the seam for quality assessment. Carbonaceous shale bands
having thickness more than 30cm have been excluded from the seam
thickness.
I10 Sample: including both combustible and non-combustible bands upto
0.10m thickness. This analysis has been carried out for the seams having
quarriable potentiality.
I100 Sample : 'Bcs' sample + carbonaceous shale (ash + moisture upto
75%) bands upto 1m in thickness + grey shale (ash + moisture >75%)
bands upto 1m in thickness and excluding all other obvious bands such as
sandy shale, shaly sandstone, sandstone etc. irrespective of their
thickness.
Ip Sample: I100 Sample + carbonaceous and grey shale bands irrespective
of their thickness and excluding all other obvious bands as in I100 Sample.

CHAPTER –X
WATER MANAGEMENT (PUMPING AND DRAINAGE)
10.1 GENERAL
The general surface topography in the project is such that that surface
drainage is not likely to pose any major problems as no major nallah do
not traverse quarriable area. The area drainage is by Kewai River and
Hasdeo River.
Garland drains will be provided around the mine to keep the runoff water
away from the quarry. Fresh drains will be made as mine advances. The
drains will be connected to the natural drainage of the area. The drains
will be cleaned periodically to avoid overflow of the same. Embankments
will be provided around the mine wherever necessary to protect the mine
from flooding.
Efforts will be made to lay the benches and haul roads in such a way that
water will gravitate towards the main sump located at the deep most point
available at the current workings. The slope of the floor of benches will
be made such a way that water flows down to the sump to keep the
benches dry.
10.2 SOURCE OF WATER In general the sources of water inside the quarry are as given below:- - Direct rainfall in the excavated area
- Inflow of water from back filled area due to rain fall on it
- Inflow of water from area beyond excavation due to rainfall on it
- Seepage of water from strata water/Ground water
10.2.1 Direct rain fall in excavated area:-
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 10 / 2 of 10
The rain water falling directly in the excavated area will flow down and
collected in the sump. It is assumed that 90% of water falling in this area
will be collected in the sump.
10.2.2 Inflow from back filled area:-
A part of rainwater falling on the Internal dumping area will flow down into
the mine. As the internal dump will be relatively loose so run off
coefficient into the mine has been considered as 0.1.
10.2.3 Inflow from area beyond excavation:-
A part of the rain water falling in the area beyond excavation will find its
way into the mine. Garland drains will be provided around the mine to
arrest the outside water so it is assumed that 10% of rain falling in this
area will flow down into the mine and collected in the sump.
10.2.4 Seepage from strata: / Ground water
There will be some seepage from Strata/ Ground water. This seepage
during dry season say November-June is expected to be low. During
monsoon and post monsoon period i.e. July-October the seepage will be
more. This is assumed as 10% of make of water in the mine.
10.3. MAKE OF WATER
10.3.1 General considerations
The general parameters considered for calculating the pumping
requirements and make of water are as given below:-

(ix) Time required to dewater the entire Water including 10% pump losses 100 hours (x) Pumping losses 10% 10.3.3 Assessment of maximum rainfall in a day
The assessment of maximum rainfall in a day during the life of the project
has been made by drawing a probability curve (fig 10.1) based on
calculated/theoretical values and observed values of the maximum rainfall
in a day, life of the project etc.
i) Probability based on observed values:-
The maximum rainfall in a day at J&K Area for the period 2001-2011 has
been arranged in the descending order and the probability of the same
was calculated and tabulated below in the descending order :-

10.4. SUMP
A sump will be provided at the deep most point of the mine. The sump will
be shifted as the mine advances. The layout of quarry provides suitable
gradient along the floor of the benches to facilitate self drainage of water
into the sump.
During heavy monsoon period, the work in the lower most benches may
be drowned as it will not be possible to pump out the entire make of water
in the wettest day. Therefore, it is proposed to drown a part of the lower
most bench which will work as a sump to accommodate the required
quantity of water which will be equivalent to the water accumulated due to
a rainfall of 172 mm in a day (at 10% probability).
Water from the sump will be pumped to surface which will pass through
sedimentation ponds before finally discharged into natural drainage
system. Sump will be cleaned periodically to avoid silting and mud
accumulation.
10.5.0 PUMPS
Nine numbers of main pumps each of 225lps, 160m head (along
with energy efficient motor) will be provided to meet the requirements up
to 21 years. Out of nine pumps six nos. will be working & three will be
standby. Some of the stages of the main pumps may be blanked when
they have to operate at shallow depths. This has been provided to reduce
the capital investment and utilize the pumps till the end of life. Provisions
have been made considering the peak demand which is occasional.
Further the pumps may be repaired and kept ready for use in rainy
season. Main pumps will be installed on pontoons. Provision of pontoons
for each main pump has been given in the estimate. After 10th year of
mine operation the depth of mine would be around 145m, so proper care
has to be taken to arrest water at upper seam. Thus stage pumping could
be avoided.

The requirement of pumps has been shown for entire life of the mine;
however procurement shall be made as per requirement.
During heavy rainfall, overburden may be washed away from edges
of slopes and internal dumps, pumps capable of slurry handling will be
required. Pumping of clear water and slurry will be from upper and lower
part of sump respectively.
10.6 PIPING ERW pipes of 355.6mm outer diameter will be used for carrying the
discharge from 225lps capacity pumps. Similarly, ERW pipes of 273mm
outside diameter will be provided for carrying the discharge from 80lps
capacity main pump / diesel engine operated pumps and 219mm diameter
pipe will be provided for discharge from 38lps submersible pumps. Initially

their wheels. Provision of adequate nos. of water sprinklers and adequate
lengh fixed type of water sprinkler have been made for spraying of water
on haul roads to prevent emission of dust. Haul roads and other heavy
duty roads likely to be negotiated by heavy vehicles and equipment have
been proposed to be metalled and coated to facilitate control of emission
of dust.
The drills to be engaged is to be equipped with dust arrester so that dust
emission is minimum. As the blasting is not continuous one and while
blasting, persons will be removed to the safe zone to reduce exposure to
dust created due to blasting. At siding, sufficient arrangements have been
provided to suppress coal dust at vulnerable points.
15.4 SLOPE STABILITY
SPOIL DUMP
The spoil will be stacked in the external and internal dump space at the
natural angle of repose to avoid the sliding of OB bench. The OB dump
will be terraced at the height of 30m. The barrier distance between internal
dump and coal production bench will be 100 m to have smooth functioning
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI

16.1.4 Flora and Fauna
As per one season environmental baseline data generated (year: 2014) for preparation
of EMP of Amadand OCP, Flora & Fauna data has been taken into reference. Summary
of the flora and fauna study is given below.
The study area comprises of Tropical Moist Deciduous vegetation. Several tropical
elements can be seen scattered in the area. Shorea robusta, Anogeissus latifolia,
Tectona grandis were the most common species in forest. Acacia auriculiformis, Alstonia
scholaris, Bauhinia spp. and Cassia fistula were common in avenue plantation. Tree
species viz Mangifera indica, Dillenia aurea, Messua ferrera, Syzigium cumini, Terminalia
arjuna , Treama aurientalis, Diospyrous malabarica, Ficus racemosa, , Anogeissus
latifolia, etc. are found planted along the boundary of the agricultural lands and along the
road sides. Amadand mine lease area has running mine quarries and does not support
healthy vegetation. Main flora of the region includes plantation along the road side and
avenue plantation. The tree species observed in the area are, Albizia procera, Albizia
lebbek, Leucaena leucocephala, Delonix regia, Bauhinia variegate, Syzigium cumini, etc.
The major part of the study area lies under agriculture field and human settlements which
restrict the wildlife habitat significantly. Most of the mammalian species reported in the
study area are domesticated animals. There is neither any wildlife sensitive area nor any
corridor for the movement of wildlife is present in the study areas. Common Myna,
Kingfisher, Spotted dove and Pintail are some dominant bird species present in the study
area. Migratory movement of birds in the study area has not been reported. As far as the
reptile community was concerned, rat, snake, and house lizard are reported from the
study area.
Biodiversity conservation plan is developed with the aim to reduce the anthropogenic
pressure on natural resources due to accelerated pace of habitat change and natural
resource utilization. It needs a sustainable use and management of resources, identifying
and conserving critical habitats of wildlife and conservation of endangered and Schedule-
I species. Conservation plan also include the active participation of local communities.
The biodiversity management and conservation plan has been formulated considering
the wildlife (fauna and flora) profile of the region, customs, cultures & traditional rights of

Peafowl is present in study area having high conservation value.
16.1.5 Socio-economic Status
The project envisages 1443.01 Ha of land for quarry, infrastructure, residential
complex, safety zone and external dumps etc. This includes 702.379 Ha of land already
acquired for the existing Amadand OCP (1.15 Mty). Remaining 740.626 Ha land has to
be acquired for Amadand OC Expansion (1.15 to 4 Mty). The approximate number of
Project affected families likely to be rehabilitated is 1100. The families going to be affected
by acquisition of tenancy land / agricultural land are to be compensated economically and
jobs to the eligible land oustees / losers have to be provided as per M.P R and R Norms.

be recycled through Oil and Grease trap and sedimentation tank.
Domestic Effluent Treatment: -
The sewerage disposal system for the colony exists with conventional septic tank
and a soak pit arrangement. As a part of Environmental Control Measures in township
the money to be spent for Sewerage Disposal in Colony is 29.63 lakhs and for Sewerage
Treatment Plant is 400 lakhs.
Water Conservation: -
The waste water recycling after due treatment will enable conservation of water.
The clear water after sedimentation & treatment will be reused for water sprinkling,
plantation & agriculture purpose, ground water recharge & for use by the local villagers
etc. Workshop effluents will be discharged and treated through Oil and Grease trap and
sedimentation tank.
Storage of conserved water in mine pits would be given due emphasis to provide
water round the year and the quality of water would be maintained. The balance left mined
out area of 250.41 Ha would be treated as water body after mine closure. The maximum
depth of the void is 130 m from ground level. The water body would serve as a
considerable source of water for the use of local population after final closure.
Control measures adopted against impact on ground water regime:-
i) The impact will be limited to a smaller distance and for a temporary period. The effected
habitation will be provided with suitable drinking water supply by sinking hand pumps in
the habitat.
ii) The entire mine industrial water demand, would be met from the treated mine
discharge. The wastage of water will be minimized.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
Job No.515126 Chapter 16 / 15 of 24
iii) The surplus treated mine water will be discharge into the agricultural fields. Thereby,
the mine water will behave as constant source of recharge and improves the water levels
in the mine area. This will also become a resource for the local public and increase
agriculture output.
iv) So also, after cessation of mining, part of the quarry area will be reclaimed with highly
permeable OB material. The final void would be converted into a water reservoir. Thus,
in post-mining, the recharge and source potential in core zone will be much higher than
the existing.
v) With the increase in secondary porosity, a significant improvement in the rainfall
infiltration rate, close to the mine area can be anticipated.
16.3.3 Noise Management
The present noise levels are below the prescribed limits. If the impulsive noise
levels increase due to mining operation, suitable measures will be adopted to maintain
the noise level within permissible limits at working zone. The following measures are
adopted and will be continued:
1. Planting of rows of trees with thick foliage along roads and other noise generating
centers to act as acoustic barriers.
2. Isolating/enclosing the noisy machines/sources by using resilient mounting/altering
structures.
3. Routine maintenance schedules for HEMM and other machineries to eliminate noise
as far as possible.
4. Balanced and properly aligned conditioning of machines to reduce vibration.
5. Provision of ear muffs/ear plugs to workers subjected to noise level above
recommended limits.
6. Controlled blasting.
7. Regular monitoring of noise level of project area.
16.3.4 Flora and Fauna Management
The location of Amadand OCP does not have any importance as a holiday resort.
The surface to be disturbed by open cast mining operation does not contain any rare
variety of flora or fauna. As such, consequent to the opencast mining operation,
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
Job No.515126 Chapter 16 / 16 of 24
deterioration in quality of life or loss of amenity is not envisaged. Conservation plans of
schedule I & II animals, if any, will be prepared and implemented.
Compensatory afforestation and Strengthening of safety zone will be done.
The reclaimed and afforested internal dump and external dump of 841.31 Ha will
form one integral unit at the cessation of the mining activity. SECL will develop this
integrated area, as habitat for the fauna. The following steps will be taken for development
of habitat.
Reclamation of mine void:
In the core zone, after the cessation of mining activity a void will be created. This
void will be used as a water body. This will be graded to a gentle slope so that it acts as
a safe approach / access to the water body for the faunal species.
Through CSR activities in villages existing in the buffer zone, existing water
sources particularly the village tanks will be improved to provide drinking water to the
local community so that biotic pressure on water resources present in the forest areas
and used by fauna is gradually reduced.
Control of forest fire, fire in coal seam and coal stock:
Fire can destroy the entire habitats (micro and macro) and its life supporting
potential in a forest area. Fire does not spare fauna also. SECL will implement the
existing DGMS stipulated fire protection norms on coal seams and coal stock. This will
ensure that a congenial atmosphere is created and fire does not affect the fauna and flora
as well.
16.3.5 Land Resource Management
The project involves 715.02 Ha of land for the quarry area. This includes 70.46 Mt
(as on 01.04.2015) of mineable coal and 764.40 Mcum of OB. In the initial years i.e. upto
4th year, entire OB will go to the external dumps. Internal dumping will start from the 5th
year onwards. The parting OB in case of older seams may be transported through central
haul road, while mining in the multi seam zone.
Initially, the soil/alluvium from top bench of OB will be stacked and stored
separately. The spoil dump benches in the internally backfilled OB will be in the form of
benches. With the sufficient advance of coal production bench, the backfilled OB will be
leveled with dozer.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
Job No.515126 Chapter 16 / 17 of 24
Dumper/Tipper will transport soil/alluvium OB from the top OB bench and will dump
the soil directly on the leveled backfilled OB. The barrier distance between internal dump
and coal production bench will be 70 m to have smooth functioning of machineries. The
slope stability study should be done. According to study report, the dump design like
dump bench height, total dump height & slope etc. should be modified to avoid dump
failure. In addition to that proper precautions should be taken to avoid sliding of internal
OB bench.
238.02 Mcum OB will be externally dumped outside quarry area from 1st year to
10th year for which 356.50 Ha land will be required.
External dump has been made near southern boundary. The break-up of OB
quantity to be accommodated in various dumps is as follows
Table 16.10 Dump Volume (Mcum)
A. External 238.02 B. Internal 526.38
Grand Total (A+B) 764.40
Present land use would be converted into internal dump, external dump, green
belt, built up area, surface infrastructure, final void/water body & other surface water body
etc. after the cessation of mining operation. Out of 715.02 Ha. of quarry area, plantation
would be done in 464.61 Ha. The dump surface would be maintained flat and top soil
would be sprayed over it as a part of final reclamation.
Plantation would be done on reclaimed internal dump, external dump, safety zone
and around the mine, infrastructure, etc. The no. of plantation is given as under.
a. Mine, infrastructure, colony etc. 58825 Nos, in 23.53 Ha.
b. Internal Dump after backfilling: 1161525 No.s, in 464.61 Ha
c. External Dump: 941750 Nos in 376.70 Ha
d. Safety zone* : 290000 No.s in 116.00 Ha
Total Plantation = 2452100 Nos.

MINE CLOSURE PLANNING
18.1 Closure Planning details of mine
Amadand OCP is an operating mine under Jamuna & Kotma Area, SECL and
comprises mostly (i.e. 1313.22 Ha, 91 %) of tenancy land. The expansion project area is
not involved with any industrial and mining activities for which require regular
environmental monitoring/audit. Environmental base line data for Amadand OC
Expansion, generated in the year of 2014, are utilized for preparation of this Chapter.
This data will enable to obtain a comprehensive idea of environmental quality in
and around the proposed project area in respect of air quality, water quality, noise level,
flora fauna, socio economic data etc. The project has been planned for a target capacity
of 4.0 Mty for 19 years life, to meet power grade coal. Beyond this life, the mine will be
closed if no further expansion towards the above adjoining blocks is considered. The
closure details are described below.
18.1.1 Mined out Land & proposed final land use;--
The proposed pre-mining and the tentative post mining land use plan has been
given below in table 18.1(a), (b) & 18.2 (a), (b).

d) Water Conservation
The effluent generated in the workshop will be recycled for washing of vehicles. Steps
will be taken to maximise the reuse of effluent generated from the mine and colony.
Rainwater harvesting structure will be provided in the office/ colony at suitable place for
water conservation. The waste water recycling after due treatment for the purpose
mentioned above will enable conservation of water. Storage of conserved water in mine
pits will be given due emphasis to provide water round the year and quality of water will
be maintained before and after storage. An amount of 6.00 lakhs has been provided for
the rain water harvesting in the colony areas.
e) Water balance of the area (from EMP)
Except for coal mining, no major industrial development activity is located in the area.
As per CGWB, NCC Region, Raipur, the total annual replenishable ground water resource
in the Anuppur Development Block, Shahdol district (where Amadand UG proposed mine
exists), was assessed as 68.20 M.cum. It was also reported that the ground water
development in the block is as 1.99 % and falls within category "Safe". As such, the entire
Madhya Pradesh & Chhattisgarh States are covered under the category “Safe”. On
analysis, the net groundwater recharge and draft for the buffer zone were
estimated as 45.55 MCum and 33.73 MCum respectively. Thus, about 11.82
MCum groundwater recharge would be available annually in the area to meet any
future demand.

f) Acid mine drainage source, the existing practice of control and future plan
The existing mine water quality of Amadand & nearby mines are not acidic and it is
expected the acid mine drainage problem will not arise in Amadand OCP also. If however
acid mine drainage problem arises suitable measures will be taken as per standard.
g) Underground water/ quarry water management after closure (Specifying its
usage like domestic water supply, irrigation, and pisciculture or stabilizing the
ground water regime).
The final void (250.41 Ha) left after the completion of mining activity will act as a
water recharge basin for the area and may be utilized by the local community.
h) Water quality monitoring for three years after closure
The number of sampling stations shall be one with the quarterly sampling frequency
and two numbers ground water samples in core and buffer zone with quarterly frequency.
A monitoring schedule for Water levels will be as per Standards of MOEF (Vide
GSR 742 (E) dated 25.9.2000)

18.7 Waste disposal
a) External OB dump & internal backfilling details (specifying the reclaimed
backfilled area, area of voids for water reservoir and also the OB dump area height
and volume) prior to closure of mine or during progressive mine closure
The project involves 715.02 Ha of land for the quarry area. This includes 70.46 Mt
(as on 01.04.2015) of mineable coal and 764.40 Mcum of OB. In the initial years i.e. upto
4th year, entire OB will go to the external dumps. Internal dumping will start from the 5th
year onwards. The parting OB in case of older seams may be transported through central
haul road, while mining in the multi seam zone.
Initially, the soil/alluvium from top bench of OB will be stacked and stored
separately. The spoil dump benches in the internally backfilled OB will be in the form of
benches. With the sufficient advance of coal production bench, the backfilled OB will be
leveled with dozer.
Dumper/Tipper will transport soil/alluvium OB from the top OB bench and will dump
the soil directly on the leveled backfilled OB. The barrier distance between internal dump
and coal production bench will be 70 m to have smooth functioning of machineries. The
slope stability study should be done. According to study report, the dump design like dump
bench height, total dump height & slope etc. should be modified to avoid dump failure. In
addition to that proper precautions should be taken to avoid sliding of internal OB bench.
238.02 Mcum OB will be externally dumped outside quarry area from 1st year to
10th year for which 356.50 Ha land will be required.
External dump has been made near southern boundary. The break-up of OB
quantity to be accommodated in various dumps is as follows
Table 18.6 Dump Volume (Mcum)
A. External 238.02 B. Internal 526.38 Grand Total (A+B) 764.40
Present land use would be converted into internal dump, external dump, green belt,
built up area, surface infrastructure, final void/water body & other surface water body etc.
after the cessation of mining operation. Out of 715.02 Ha. of quarry area, plantation would
be done in 464.61 Ha. There would be a final void/water body of 250.41 Ha left in the

project after mine closure The dump surface would be maintained flat and top soil would
be sprayed over it as a part of final reclamation.
Plantation would be done on reclaimed internal dump, external dump, safety zone
and around the mine, infrastructure, etc. The no. of plantation is given as under.
a. Mine, infrastructure, colony etc. 58825 Nos, in 23.53 Ha.
b. Internal Dump after backfilling: 1161525 No.s, in 464.61 Ha
c. External Dump: 941750 Nos in 376.70 Ha
d. Safety zone* : 290000 No.s in 116.00 Ha
Total Plantation = 2452100 Nos.
b) Stabilization of external O.B. dumps and backfilled area (Technical Reclamation)
Technical reclamation would involve breaking and levelling the top of OB dumps,
filling of gulleys and terracing etc. The maximum depth of the project will be 152.50 m. In
the initial years i.e. upto 4th year, entire OB will go to the external dumps. Internal dumping
will start from the 5th year onwards. The parting OB in case of older seams may be
transported through central haul road, while mining in the multi seam zone.
The height of each waste bench is restricted to only 30 m. The decoaled area after
simultaneous backfilling will be levelled by means of dozers keeping a mild slope of about
1 in 200 for surface water drainage for plantation and other purposes.
To the extent possible, top soil will be removed and stored separately. This soil
will be directly spread over the levelled graded external & backfilled OB for reclamation
Biological reclamation work will follow in next progressive year.

a) Top soil Preservation & Management
The objectives of Top Soil Management are to-
Maintain a topsoil balance that achieves rehabilitation objectives during the life
of mine.
Ensure effective topsoil removal techniques are employed to maximize volumes
of suitable topsoil removed and minimize wastage.
Maintain topsoil viability during stripping, spreading, and stockpiling, through
best practice techniques and effective stockpile design and treatment.
In accordance with the objective of providing sufficient stable soil material for
rehabilitation and to optimize soil recovery, the top soil management the stock
piling of topsoil will be practiced as follows:
i) Top soil and other materials removed shall be stock-piled only when it is
impractical to promptly redistribute such materials on re-graded areas.
ii) Stock-piled materials shall be selectively placed on a stable area, not disturbed,
and protected from wind and water erosion, unnecessary compaction, and
contaminants which lessen the capability of the materials to support vegetation
when redistributed.
iii) The stockpiled top soil is preserved by adding–up organic material, manure and
other similar amendments.
iv) Uniformly distribute topsoil to suitable thickness. If sufficient topsoil is available,
a minimum compacted depth of a half meter on 3:1 slopes and one meter on flatter
slopes is suggested.
v) Specific team / manpower are to be deployed for this most important step of
topsoil management. The team will monitor the area and quantum of top soil
management with the authorities of mine on quarterly basis and regularly monitor
the given points of significant importance.
vi) Organic or inorganic fertilizer should be applied periodically if vegetation growth
is poor.
vi) Regular monitoring of top soil management should be done until vegetation is
demonstrated to be successfully established.

18.12 MINE CLOSURE COST
The mine closure cost will cover the various related activities for which a corpus
escrow account @ Rs. 6.0 lakh per Ha for Opencast mine of the project area shall be
opened with the coal controller organization. The above amount is as per the mine closure
guidelines issued in August 2009, which will be updated for the present financial year
based on the cost index value.
18.11.1 Mine Closure Cost for OC mine
As per the guidelines of the MoC, the cost of the mine closure is to be computed
on the basis of the project area involved in the project. In Amadand OCP total land area
involved is 1443.005 Ha. The updated cost of the mine closure as on March’15 is
estimated to be Rs. 8.15 lakh per hectare (considering the admissible escalation over Rs.
6.00 lakh per Ha as on August 2009).
Final mine closure cost @ Rs = W.P.I of March 2015 176.10 /W.P.I of Aug.09
129.60 x 6= Rs.8.15 Lakh/ Ha. for 1443.005 Ha = Rs.11760.491 lakhs.
The balance life of the mine is 19 years. Hence, the management of funds in the
Escrow Account would be as follows:

Lakhs. Some existing HEMM will be transferred to other mine as in this report both coal
and OB removal is proposed to be done by outsourcing. As on 31.03.2015, Net block of
HEMM which are to be transferred from this project is Rs 3528.71 Lakhs. Net block
considered for project costing = Rs (6009.91-3528.71) Lakhs = 2481.20 Lakhs
21.1.2 Basis of price of P&M, Civil works & hiring rate
Price of P&M has been taken from the standard price list published by CMPDI, HQ on
May 2014. Prices have been updated upto July 2015 as per escalation rate given in the
price list.
The preparation of cost estimates for civil infrastructure is based on prevailing cost
index of the area in July 2015. The cost index value has been calculated from the

Specific investment - Rs. 2173.60 tonne
Specific investment for P&M - Rs. 996.90 tonne
21.2 OPENING OF REVENUE ACCOUNT The norms for bringing coal projects into revenue account as decided in the meeting
held under the chairmanship of JS&FA on 9.6.04 are as follows:-
1) Revenue expenditure to be capitalized should be net of sales receipts of coal
produced during the construction period.
2) The period of construction has to be defined to determine the commercial readiness
of the project to yield on a sustainable basis.
3) In case of opencast projects, the volume of stripping of OB and in case of UG
projects, the completion of required development activities during the above period of
construction have to be clearly defined.
4) Based on the above, the capitalization of revenue expenses / opening of revenue
account will be decided.
Accordingly, a definition of the term ’commercial readiness of a project has been drafted
and based on this a norm for capitalization of revenue expense / opening of revenue
expenditure of a project has been suggested as under:-
A. Commercial Readiness: A project will be treated to have reached the stage of commercial readiness to yield
production on sustainable basis from the year when all the following criteria have been
achieved –
(i) 30% of the total volume of excavation (Coal and OB) envisaged in the target year.
(ii) The land required for the project upto target year has been acquired.
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI

(iii)Construction of CHP and railway siding have been completed or adequate
alternative arrangement for sizing and dispatch of coal have been commissioned for the
Project.
B. Capitalisation of Revenue Expenses based on commercial readiness:
For the preparation of Feasibility Reports, the revenue expenditure of a project can be
capitalized till the year the project achieves commercial readiness as per the plan
envisaged.
The capitalization of revenue expenditure, in no case, shall extend beyond the year the
Project achieves the status of commercial readiness.
The Amadand Opencast project is on going project with a target production of 1.15 Mty
and the project is already in operation. This RPR is being prepared to enhance the
production from 1.15Mty to 4.0 Mty.
Considering the on going project, the Revised Project Report would be brought
under revenue account w.e.f. the beginning of 1st year of operation. Thus the revenue
expenditure of the project has not been capitalized during the initial years.
21.3 REPLACEMENT CAPITAL
Year-wise phasing of replacement capital is given in Appendix-D.1 column No.3. 21.4 SOURCES OF FINANCE
The project will be financed completely by internal resources.
21.5 COMPLETION COST

A CHAPTER ON OUTSOURCING 22.1 INTRODUCTION
Outsourcing has become increasingly attractive for many organizations in
recent past. Businesses irrespective of its size, skill, knowledge and
technology are finding outsourcing mechanism most befitting in terms of
cost reduction as well as quality improvement .With globalization and
removal of barriers, outsourcing has created new opportunities for
generation of employment. Today whether it is a canteen services or
security services or courier services or gardening, is no longer one man
providing service to one organization. These are just examples and we
can go on listing them but essentially they are contractor or organizations
which provide a specialized service at a competitive price. The service
itself is much better than what an entrepreneur if he engages workmen on
his roll would be able to provide. Further, the quality of the service is much
better and it leaves the entrepreneur to concentrate on its core activity.
Outsourcing will remain in the four front of every business executive mind
as a business strategy that will let their organization to create and sustain
business value in the competitive global market for reduced cost, focus on
core business processes, improve services, enhance skills, and increase
competitive advantages.
Growth in outsourcing is expanding to include not only IT functions, but
critical business processes, as well as evolving application areas like
enterprise resource planning and re-business initiatives. Successful
companies are incorporating outsourcing as a key strategy for growth and
differentiation. No longer considered merely a tactic for cutting costs and
adding temporary staff, outsourcing is being accepted in board rooms
around the world as a critical success factor for business survival. We
RPR for Amadand OCP (4.0 Mty) (Updated July’ 2015) CMPDI
. . JOB NO.-515126 Chapter 22 / 2 of 7
need to give as much attention to managing processes as we have in the
past to managing products.
For years, outsourcing was more a matter of “out asking” – hiring outside
vendors to perform specific jobs or manage specific projects within a
department of a large organization. Many things that are done inside the
companies are labour intensive. Those are the kind of work where human
being have to intervene in a process and use decision – making skills –
such as interpretation, validation, translation, transliteration or
transformation.
22.2 SCOPE OF WORK PROPOSED TO BE OUTSOURCED i) Drilling
The external agency will prepare the site and carry out blast hole
drilling as per the pattern decided by the project authorities according
to strata conditions and stipulations of DGMS
ii) Coal cutting by surface miner
