2. Introduction of the project / Background information:

(i) Identification of project and project proponent:

Background:

There is a need to enhance power generation in the country from the present level of

148,000 MW to 380,000 MW by the year 2030 to achieve an economic growth rate of 8%

to 9%. The major share of growth in power generation is through thermal i.e., coal based.

Hence country’s coal requirement will have to be enhanced to 1300 MT. To compensate

the decrease in production from the closing mines and to meet the demand of coal in this

region, the project proponent, Singareni Collieries Company Limited (SCCL), a

Government Company is planning to open new mines in the new blocks.

Adriyala Shaft Project was started in the year 2008. Environmental clearance was obtained

for Adriyala Shaft Project for a production capacity of 2.144 MTPA vide letter No. J-

11016/258/2004-IA. II(M) dated 11-10-2004. In Feasibility report it is envisaged to deploy

two Longwall units in this project. Due to drastic development in Longwall technology

worldwide, it is proposed to deploy one high capacity Longwall unit instead of two and to

produce 3.14 MTPA from the same mine.

Identification of the project:

Adriyala Shaft Project is an underground mine located in Adriyalla Project area(APA) of

SCCL. Rated production capacity of the project is 2.144 MTPA. The grade of the coal

varies from G5 to G9 over the life of the project.

(ii) Brief description of nature of the project:

Adriyal Shaft Project is an underground coal mine producing G-5 to G-9 grade coal with a capacity of 2.144 MTPA.

Present proposal envisaged for expansion project:

The project was granted environment clearance for a production capacity of 2.144 MTPA

with two Longwall sets and 150m face length. Keeping in view of the changes in

Longwall Technology globally, SCCL has decided to deploy high capacity Longwall

Technology which

is capable of producing more than 3.0 MTPA in the same minetake area by redesigning

the Longwall face length with 250m. Hence it is proposed to increase the production

capacity of the mine from 2.144 MTPA to 3.14 MTPA and to obtain environmental

clearance for this production capacity under MoEF memorandum J-11015/30/2004-IA-

II(M) dated 7/1/2014.

(iii) Need for the project and its importance to the country and or region:

Coal is the most important and abundant fossil fuel in India. It accounts for 56.42% (Source: Ministry of Power, GoI) of the country's energy need. The country's industrial heritage was built upon indigenous coal. The per capita energy consumption in India rose from 30.1 kwh during 1st Five Year Plan (1951-56) to 813.33 kwh during the 2010-11 and estimated to 1000 kwh during the terminal year of 11th Five Year Plan (2011-12). Considering the limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on Hydel project and geo-political perception of nuclear power, coal will continue to occupy centre-stage of India’s energy scenario. The generation capacity of Coal and Lignite based Thermal Power Plants in India raised from 1004 MW during the year 1950 to 93918 MW during the year 2011 (Source: Ministry of Power, GoI).

The coal reserves of India up to a depth of 1200 m have been estimated by the Geological Survey of India at 285.67 billion tones as on 1.4.2011 (Source: MoC, GoI). Coal production is insufficient to cope up with growing demand for electricity and industrial energy. During the terminal year of 11th Five year Plan i.e. 2011-12, the actual domestic coal production was only 539.79 MT against the demand of 696.03 MT and the gap of 156.24 MT was imported from the Australia, Indonesia, South Africa and other countries. As per the working group of Ministry of Coal, Government of India, a supply

7

gap of about 265.50 million tones is forecasted by the terminal year of 12th Five Year Plan i.e. 2016-17. Even the increase in production is considered in optimistic scenario the gap of 185.50 MT will still be left by TY of 12th FY Plan (Source: Working Group of Ministry of Coal, GoI).

The Singareni Collieries Company Limited is only coal producing company catering the needs of energy requirements in South India. A supply gap of 16.40 million tones is projected by the terminal year of 12th Five Year Plan, i.e. 2016-17 (Working Group of MoC). Hence, SCCL is taking following steps to increase the coal production:

Reconstruction of existing mines for optimizing production with the introduction of intermediate and high technology.

Opening of new mines in the adjoining / superjacent areas / seams for higher production.

Adopting opencast working wherever possible for high rate of production.

Reconstruction of shallow underground workings for extraction of remnant coal reserves by opencast method.

Hence, the proposed project is justified in view of demand-supply gap in the country.

(iv) Demand - Supply Gap:

The below table reveals that total availability of coal from the existing projects, projects

under implementation and approved projects is inadequate to meet the total demand and a

substantial gap remains unfulfilled. Hence, opening of new mines in the adjoining /

superjacent areas / seams for higher production is justified to mitigate the demand -

supply gap.

3 Gap -3.55 -4.50 -5.10 -8.60 -15.20 -16.40

(v) Imports Vs Indigenous Production:

Certain quantity of coal is being imported to mitigate demand - supply gap in the country.

In order to reduce the imports, the various possibilities have been explored to enhance the

production indigenously and as a part of capacity building of existing mines, the present

proposal was made.

(vi) Export Possibility:

There is no possibility of export of coal from this mine as the project is linked to power plants of NTPC and also there is sufficient demand for industries located in AP and elsewhere in India.

(vii) Domestic / Export Markets:

The coal produced is fed to the major domestic customers namely Power Sector, Cement Industries, Fertilizers and Brick Industries etc.

(viii) Employment Generation (Direct and Indirect) due to the project:

The present proposal is to increase the production capacity from the existing project by increasing the efficiency of the existing system with the existing establishment. As such,

8

there will not be any additional man power required for the project, however, indirect employment opportunities due to coal transportation, material supply, out sourcing operations will be increased to local people.

vi. Raw material required along with estimated quantity, likely source, marketing area of final product, mode of transport of raw material and finished product:

Raw material required along with estimated quantity:

Coal is natural resource and does not require any raw material for production of coal. However in the process of extraction of coal explosives, hydraulic oils etc are used for the equipment deployed in the mine.

Mode of Transportation of Raw Material:

NA

Marketing area of final product:

Coal from this mine is transported to RG OC-I CHP from there it is supplied to NTPC Ramagundam, and to other cement industries

Mode of Transportation of Finished Product (Coal):

The coal obtained from this project is transported to RG OC-I CHP located at a distance of 10Km by belt conveyors, from there it is supplied to NTPC and other power plants by rail.

vii. Resource optimization / recycling and reuse envisaged in the project, if any:

Resources like explosives, hydraulic oils, machinery, land, power and water are fully optimized to minimize unnecessary losses during the process of extraction of coal and supply of coal to the customers.

As the coal mining process does not involve any chemical process, the excess pumping of water will be useful for domestic purpose, drinking and irrigation to nearby fields. The effluents from workshop and township will be treated in ETPs and Oxidation Ponds respectively and waste water will be utilized for watering plantations, parks, lawns, gardens and for spraying arrangement for dust control, etc.

Excess water let out from the mine will be treated in settling tanks / slow sand filters before discharged and used for agriculture purpose. The surplus water is being let out for irrigation of surrounding fields.

viii. Availability of water, its source, Energy / Power requirement and source:

The water required for the project will be met from the water pumped out from the mine workings. In the process of mining, water will be accumulated in the dip most places of the mine due to natural seepage. The water so accumulated will be collected in sumps at different places in the mine and pumped out to the surface with suitable capacity pumps. The pumped out water will be filtered on the surface and used for drinking and other mining operations on the pit head as well as supplied to the colonies. The estimated water to be pumped out from different sections of the mine and its usage is as follows:

SL No Description Quantity in KLD

1 Average quantity of water pumped out of the mine 13000

2 Water used for drinking/bathing and other industrial requirement

250

substation power is stepped down to 3.3 KV and supplied to underground machinery. In

Adriyala section power is supplied to Trunk conveyors at 11KV, for remaining machinery

at 3.3 KV.

ix. Quantity of wastes to be generated (liquid / solid) and scheme for their management / disposal:

In underground mine, wastes generated during the mining is very less compared to that of

opencast mining.

The solid waste generated will be generally the stone bands / dirt bands / shale produced

during mining activity. The debris so produced will be used for underground track

ballasting, leveling of the uneven floors and strengthening of surface bank head. The other

wastes will include decayed timber in small proportions.

The liquid wastes like used oils, grease etc; will be stored in separate tins / drums and sent to surface at regular intervals for disposing as per Hazardous Waste Management Rules.

Area Administration:

The mining activities are being carried out in Ramagundam III Area since 1970. The Present Adriyala Shaft Project comes under the administrative control Adriyala Project Area. Hence, there is no need of further construction of area level administrative buildings.

(iii) Green Belt:

It is proposed to carry out plantation as a part of Green belt development at areas along the roads, around the CHP, MMV house, mine colony interface to dampen the noise, all over surface in the mine take area, along ML boundary and also in township outside lease area.

(iv) Social Infrastructure:

Social Infrastructure available in the Ramagundam III Area is sufficient to cater the needs of the employees working in the mine. Further there is 150 bedded Area Hospital to cater the hospitalization needs of workmen. Company has extended the hospitalization facility free of cost for the white card holders and also at nominal cost for the population residing in and around the project area. Community Hall and School is available for the company employees as well as the local population constructed and operated by the company at nominal rates.

(v) Connectivity (Traffic and Transportation Road / Rail / Metro / Water ways etc.):

Roads: Adriyala Shaft Project belonging to Adriyala Project Area (APA) are located in

Manthani Mandal of Karimnagar district of Andhra Pradesh. APA area is well connected

road. APA area is well connected to the state capital, Hyderabad both by rail and road and

is 225km by road.

Railways: The nearest Railway Station is Peddapallil on the Kasipet-Balharsha line of

south central railway is about 20km.

(vi) Drinking Water Management (Source and Supply of Water):

The water required for drinking within the project (including lean season) will be met

from the pumped out water from underground workings of the proposed project after

necessary treatment. The excess water from the proposed mine can be supplied to nearby

villages / colonies.

The water produced in the mine during mining activity due to natural seepage will be collected at identified sumps and will be pumped out to surface by means of suitable capacity of pumps. The mine discharge water may contain coal fines and contamination due to underground mechanization, need sedimentation and filtration before using for drinking at the mine and supplying to colonies for domestic purposes like drinking, washing, bathing etc.

19

Filter beds will be constructed on the surface for filtering the mine water in different stages to make it useful for the mine needs and other purposes. The pumped out water from different sections of the mine and its usage is as follows:

SL No Description Quantity in KLD

1 Average quantity of water pumped out of the mine 13000

2 Water used for drinking/bathing and other industrial requirement

250

3 Water used for plantation 200

4 Used for dust suppression 1050

5 Excess water let out 11500

(vii) Sewerage System:

The sewerage system has already been established in the township and the sewerage of the

colony is being treated in Oxidation Pond and is let out for plantation. The sewage water

from mine is being treated in septic tank followed by soak pits..

(viii) Industrial Waste Management:

Disposal of effluents:

As the coal mining does not involve any chemical process, the mine discharge may

contain coal fines, which will be let out into natural streams after removal of suspended

solids. The other source of concern would be the domestic and service building effluents.

The domestic effluent is being treated in septic tank followed by soak pits and effluents

from workshops will be treated in Effluent Treatment Plant.

Disposal of Solid Waste:

The solid waste generated from the proposed project

a) While shaft sinking in the sub- soil for mine entries and

b) While driving tunnels in hard rock and bottom stone blasting for leveling purpose etc

The maximum depth of the workings will be around 440 m from surface. The shaft

sinking and tunneling involves excavation of soil & stone by drilling and blasting. The

solid waste produced during drivage of tunnels and shaft sinking will used for

preparation of bank head at surface and debris so produced from inter-seam drifts will

be utilized for underground track ballasting, leveling of the uneven floors and

strengthening of surface bank head. Further, the rejects from mine and CHP’s will be

used for laying road, filling cracks developed due to subsidence and pitching of

embankments etc.

In the coal extraction process, coal-containing impurities such as shale or sometimes

sandstone will be transported to the coal handling plant. Here, the shale and sand stone

will be picked out manually. This solid waste will be in the form of lumps. The solid waste

disposal sites are identified in the low-lying areas and subsidence areas of SCCL. Hence,

no appreciable impact is anticipated due to disposal of solid wastes.

(ix) Solid Waste Management:

The coal produced from the mine is not washed or treated otherwise. The separation of Shale / stones etc is done manually within the mine and also in the CHP.

20

The debris so produced is being utilized for underground track ballasting, leveling of the

uneven floors and strengthening of surface bank head.

The solid waste from the townships will be collected from the collection bins and tricycles

provided by SCCL. The domestic solid waste collected will be transported to the disposal

sites of SCCL. The solid waste disposal sites are identified in the low-lying areas and

subsidence areas of SCCL. Hence, no appreciable impact is anticipated due to disposal of

solid wastes.

(x) Power Requirement & Supply / Source:

Adriyala Shaft Project is receiving power from Centenary colony, RG III 132/33 KV SCCL Sub-Station.

Source of power supply : SCCL 132/33 KV Sub station

Receiving voltage : 33 KV OHT Line (Double circuit)

Metering equipment : At 33/3.3 KV Substation

Adriyala Shaft Project has one independent substation at surface which is fed from 132/33 KV SCCL substation located at centenary colony by feeder No-9,12 at 33 KV. At this substation power is stepped down to 3.3 KV and supplied to underground machinery. In Adriyala section power is supplied to Trunk conveyors at 11KV, for remaining machinery at 3.3 KV.

7. Rehabilitation and Resettlement (R & R) Plan:

Rachapalli village is present over the mine take area. However this R&R will be taken up under RG OC-II project as the OB dumps are proposed in this area. 750 PDFs are involved and Rs136.25 Crores of R&R funds are envisaged.

A major part of this labor force will be mainly from local villagers who are expected to engage themselves both in agriculture and project activities. This will enhance their income and lead to overall economic growth of the area.

The following changes in socio-economic status are expected to take place with this project.

The project will have a strong positive employment and income effect, both direct as well as indirect. Migrant - non-migrant ratio will shift towards migrant side because a number of people will migrate towards the central region of study circle in the years to come. This will happen because of better indirect employment opportunities due to this project.

The project is going to have positive impact on consumption behavior by way of raising average consumption and income through multiplier effect.

The project is going to bring about changes in the pattern of demand from food to non-food items and sufficient income is generated.

The project will help in the development of social infrastructures / such as.

- Education facilities

- Banking facilities

- Post offices and Communication facilities

- Medical facilities

- Recreation facilities

- Business establishments & Community facilities

- Plantation and parks

Other Tangible Benefits

- Indirect employment opportunities to local people in contractual works like housing

construction, transportation, sanitation, for supply of goods and services to the

project and other community services.

- Establishment of coal based / dependent industries in the area

- Market and business establishment facilities will also increase.

- Cultural, recreation and aesthetic facilities will also improve.

- Improvement in communication, transport, education, community development and

medical facilities.

- Overall change in employment and income opportunity.

24

- The State Government will also be benefitted directly from the proposed project,

through increased revenue from royalties, excise duty and etc.

- The project specific CSR activities will enhance the Infrastructure facilities thereby

creating indirect employment for the people of the surrounding villages.

Risk Factors Analysed

The following risk factors are analyzed.

- Operating in low height seams

Justification:

- To reduce the gap between the demand and production of the coal in the country and

to maintain the sustained growth of the company by improving productivity and

profits. Ultimately it gives financial and social benefits for the local people there by

improving their standard of living.

- Optimization of the existing mine improves the overall financial performance of the

mine and the increase in production will pave way for further increase in

ancillary/support/dependant industries in the surrounding villages.

ADDENDUM TO ENVIRONMENTAL IMPACT ASSESSMENT / ENVIRONMENT MANAGEMENT PLAN

1. Introduction

Adriyala Shaft Coal Mining Project is an existing underground project in the

Ramagundam Region of the Singareni Collieries Company Limited. The project was

started during April 2008 with a rated capacity of 2.144 MTPA in the Project area of

363.90 Ha after obtaining environmental clearance vide J-11016/24/2004-IA.II (M) dated

11.10.2004.

Presently SCCL is producing 50.46 MTPA against demand of 57.50 MTPA. The gap

between demand and supply is 7.04 MTPA. As per the working group of Ministry of Coal,

Government of India, the gap will become 16.50 MTPA in the region by the terminal year

of 12th Five Year Plan (i.e. 2016-17) even after taking up new projects. In order to reduce

the gap between demand and supply, SCCL proposed to enhance the production from

potential existing mines.

Hence, it is proposed to increase the production capacity of Adriyala Shaft Coal Mining

Project from 2.144 MTPA to 3.14 MTPA without lateral expansion in Mining Lease area.

2. Purpose of the report

It is proposed to increase the production from the existing operations from 2.144 MTPA to

3.14 MTPA and obtain Environmental Clearance under the provisions of MoEF’s OM

dated 07.01.2014. As per the Office Memorandum one time capacity expansion up to

50% or 1 MTPA whichever is more is allowed in the existing mining lease area without

conduct of further Public Hearing.

In this connection, an addendum to the earlier EIA/EMP addressing the environmental

issues of increase in the production is presented hereunder.

nearest gauging station is varying from 621.1 mm (2004) to 1697.3 mm (1983), with a

mean of 1096.97 mm and median of 1104.69 mm. Nearly 85% of the annual rainfall is

received during the SW monsoon.

As per Indian Meteorological Department (IMD), the drought is considered "moderate", if

the deficiency is between 26 and 50 per cent, and “severe" if it is more than 50 per cent.

The percent deviation of rainfall from mean and the status of drought conditions are

furnished in Table-1. The rainfall in the recent years indicates that moderate drought

conditions prevailed four times (2001, 2002, 2008 & 2009) and severe drought conditions

also occurred during 2004, 2007 and 2011.

4.7 Land Use based on Satellite Imageries:

Introduction: M/s The Singareni Collieries Company Limited, Kothagudem is holding a

mining lease of Adriyala Shaft Project for an area of 363.90 Ha at Adriyala village,

Manthani mandal, Karimnagar district, Telangana State so as to mine Coal.

Scope of the Study: The scope of the study involves preparation of the report on land

use/ land cover details of the Core Zone (Mine lease area) and the buffer zone (10km

radius from the Mine lease area boundary) using latest possible satellite imageries. The

scope includes studying the topography and the drainage pattern.

Location of the Project: The mine is covered in Adriyala Village of Manthani Mandal,

Karimnagar district. The location of the Mining lease area falls under Survey of India

Toposheet No, 56N/10 and the geographical co-ordinates of the lease area as follows:

METHODOLOGY: The Digital Image Processing has been performed using ERDAS

Imagine software tools and Garmin 12 GPS has been used for Ground truthing. The IRS

PVI LISS III Multidated (Kharif and Rabi) satellite data has been geometrically corrected

with respect to the Survey of India Topo sheets. To carry out the geo-referencing, ground

control points (GCPs) were identified on the maps and raw satellite data. The coefficients

for two co-ordinate transformation equations were computed based on polynomial

regression between GCPs on map and satellite data. Alternate GCPs were generated till

the Root Mean Square (RMS) error was less than 0.5 pixels and then both the images were

co-registered.

This IRS PVI LISS III Multidated (Kharif and Rabi) satellite data has been used for the

Land Use Land Cover Analysis of Buffer Zone. The satellite image is analyzed digitally by

the method of supervised classification with necessary Ground truthing using the reference

map as well as GPS instrument. IRS PV CARTOSAT Pan A data (of Core Zone) is geo-

referenced data supplied by NRSC, Hyderabad. For better spatial resolution of multi-

spectral, the satellite datasets - IRS Resourcesat2 LISS IV and IRS PV CARTOSAT Pan A

have been merged for Core Zone to achieve better spatial resolution. The hybrid method

Fig 4.7.4 IRS PV Cartosat Pan F and IRS Resourcesat2 LISS-IV merged data of core



48

of Digital Interpretation and visual interpretation has been used to classify the Core Zone to

achieve accuracy levels. The coordinates of the boundary were collected using the GPS

for geo-referencing the boundary, during Ground truthing phase. The topography of the

buffer zone has been studied using the Survey of India Topo sheets considering the

elevations and the drainage pattern including drainage orders.

Land use / Land cover Classification for buffer zone: Digital image processing was

carried out to delineate various land use / land cover categories in 10 Km buffer Zone viz.

built up area, crop areas, forests, scrub forest, land with or without scrub, water bodies by

assigning necessary training sets, which were identified based on tone, texture, size, shape

pattern and location information. Necessary care has been taken to identify proper land use

class, where there is conflict between signatures of various classes. The interpreted map

was verified on ground at limited points and final land use / land cover map was prepared.

Various Land Use Classes Identified: The buffer zone can be broadly identified into

forest areas, built-up areas, agriculture areas and other land with or without Scrub. The

definitions of various land use classes are given below. For forest classification, the classes

following at AP Forest Department has been adopted.

Forest Cover: All the areas declared as reserve forest areas are shown in this class. The

forests can be classified based on density into following classes:

Closed Forest: Forests with tree canopy coverage above 70%

Dense Forest: Forests with tree canopy coverage between 40%-70%

Open Forest: Forests with tree canopy coverage between 10%-40%

Dense Scrub: Forests with tree canopy coverage between 5%- 10%.

Sparse Scrubs: Forests with tree canopy coverage between 1%- 5%.

Forest Blanks: Forests with tree canopy coverage less than 1%. Forest

encroachments and illegal agriculture also will be shown in this class.

Plantations: The plantations raised with in the reserve forest boundaries will be

shown in these classes.

Change Detection: Previously, the land use studies for Core and Buffer zones of

Adriyala Shaft project had been conducted in Year 2009. The comparative statement of

land use land cover studies of 2009 and 2012 are given below.

5. Environmental Impact Assessment & Mitigation Measures

The present proposal is to increase the production capacity from 2.144 MTPA to 3.14

MTPA from the same Project area as envisaged in the earlier EMP of 363.90 Ha.

4.1. Impact on Air Quality

The main sources of air pollution in the mining activity are drilling, blasting, loading,

transportation, coal handling, etc. As the present proposal is underground mining, all the

activities are confined to underground only, except coal handling at the pit head, coal

transportation outside the ML area and exhaust from the mine mechanical ventilator will

expose to the ambient air. The increase in the production capacity will also have impact

on air quality due to operations exposed to ambient air such as coal handling at surface,

transportation outside ML area and Exhaust through mine mechanical ventilator.

However, it is proposed to transport the coal from the Pit head to RG OC-I CHP through

Belt conveyor. Though there is additional coal transportation of coal, increase in air

pollution due to additional coal transportation will be minimum as it is proposed by the

dedicated belt conveyor. Hence, the impact due to coal transportation of additional

produced coal will be meager by taking necessary mitigative measures.

The increase in coal production will also contributes to increase in concentration of the

methane, dust, smoke, CO2, etc., from the mine mechanical ventilator but the impact is

meager as it will be diluted as soon as exhaust mixes with the ambient air. The impact on

air pollution due to additional quantity of coal handling at the surface can also controlled

by effective dust suppression measures.

The following mitigative measures are proposed:

Effective water sprinkling and extraction of dust by automatic interlocked water

sprinkling system at longwall face is proposed.

Coal evacuation is proposed from the face to Pit head also by belt conveyor.

Additional water sprinkling arrangements at longwall face, lump breaker, transfer

points, loading and unloading points along the belt conveyor in the underground

suitably for incremental production will be made.

Effective water spraying by mist spray is also proposed in the CHP.

Enclosing of transfer points where ever possible.

Development of green belt within the mine premises, CHP, avenue plantation

along the coal transportation belt / routes

Eight ambient air quality monitoring stations have been provided and monitoring

once in every fortnight as per the guidelines of CPCB and MoEF for the

parameters of PM10, PM2.5, SO2 and NOx. The monitoring will also be continued in

the expansion project.

To assess the location of ambient air quality monitoring locations, Automatic Micro

Meteorological Station has been established in the Ramagundam Region.

Data on ambient air quality is being submitted to Regional office of MoEF,

Bangalore as a part of Half Yearly Monitoring Reports of EC compliance and State

Pollution Control Board in the every quarter.

Vehicular emissions will be kept under control and regularly monitored.

Establishment of Belt conveyor from pit head to RG OC-I CHP completed and

from the RG OC-I CHP, the coal will be transported to the customers through Rail.

4.2. Air Quality in underground workings - Air Cooling System for Underground Mine Workings:

The mining operations of Adriyala Longwall Project involve heavy mechanization with

1000-3000 kW face machines operating at 300 – 600 m depth. Workings are extended to

about 4.5 - 6.5 Km length from surface. These high capacity machines, geo-mining

conditions and faster extraction rates add substantial heat to working environment.

To maintain comfort conditions at workplace, air quantity flow is to be substantially

increased. Under certain conditions, increase of air quantity is not possible and also

there is limitation to increase comfort by increasing the air quantity. Under these

circumstances it is required to adopt artificial air cooling arrangements to achieve comfort

at workplace for improving production, productivity and safety.

Keeping in view of the operating conditions at Longwall and Road header workings in

ALP, it is proposed to install Air-cooling system to reduce the air temperature in workings.

It is proposed to cool ventilation air of three major working areas by installing this air

cooling plant. Each working area is expected to be ventilated by 50 m3/s of air and

therefore, total amount of air to be cooled for three working area is 150 m3/s.

In this system, 50% of each of the air stream (i.e. 25 m3/s) shall be passed through Air

Handling units which would cool the air from 32 0C Td & 310C Tw to 180C. Approximate

cooling capacity required for each stream of air is 462 TR. 180C cold air (from the Air

Handling Units) will mix up with 32 0C air (in equal proportion) and produce a mixed air

temperature of 25 0C, which will get carried forward (under the overall ventilation system

of the mine) to the working area.

Considering some safety factor of about 5%, 500 TR (Tonnes of Refrigeration) of

refrigeration capacity per stream shall be required. Hence for three working areas taken

together, the total capacity requirement shall be 1500 TR.

Details of the proposed Air-cooling System:

Intake air temperature is proposed to be reduced from 32.00C to 25.00C for air flow

quantity of 150m3/s

Modeling and simulation studies have been carried out by ISMU, Dhanbad for the

design of Air-cooling system

The system consists of Refrigeration plant (Chillers) to chill the water in closed cycle


56

Chilled water circulated through Air Handling Units (AHU’s) strategically located in

intake of working districts

Refrigeration plant will be installed in underground/surface and suitably located

considering optimum/high positional efficiency. Chilled water is circulated through

insulated pipes from plant to AHU’s

Intake air of 50 m3/s is split into 2 streams of 25 m3/s. Two AHU’s will be installed

with capacity of 12.5 m3/s each (one AHU in each stream)

AHU reduces the air temperature from 32.00C to 18.00C, mixed air temperature in

each air stream will be about 25.00C-26.00C

Refrigeration capacity requirement is about 1500 TR. Refrigeration is proposed to be

achieved by installing multiple capacity water cooled screw chillers facilitating to use

partial capacity during winter

Total system power consumption will be about 2500-2500 kW at 100% load

Procurement of the system is in active stage and necessary fund provision is made for

the same in RCE June-2013 (₹ 7.0 crores). Earlier, during May 2012, Air-cooling system

of 500TR capacity was installed in underground at VK No. 7 Incline for cooling mine air

ventilating Continuous Miner workings. Due to the introduction of Air-cooling system,

work place comfort improved substantially in Continuous Miner district. It is the first of its

kind to be installed in underground coal mines of India and operating successfully.

Experience gained from the installation of VK No.7 Incline will be useful for the future

SCCL underground projects in procurement, installation and operation of Air-cooling

systems to achieve comfortable environmental conditions in mine workings.

4.3. Impact on water quality

The possible sources of water due to the proposed project activates are mine discharge

water and effluents from the workshop and sewage from the township. The increase in

production was planned by capacity utilization of longwall equipment with latest

technology longwall equipment. As such, there will not be any additional mine discharge

from the project over the earlier EMP. The maximum estimated mine discharge will be

13000 KLD. However the requirement of water for the dust suppression, workshop, etc

will increase from 800 KLD to 1050 KLD. Additional mitigative measures were proposed

to control the water pollution over the earlier EMP. Presently the consent for operation is

granted for 11550 KLD from the State Pollution Control Board


57

Hydrogeology:

Surface water potentiality: The area is drained by south-easterly flowing, perennial

River Godavari and its tributaries Jallaram vagu and Bokkala vagu.

Godavari River is an interstate river and its catchment area spreads over five states viz.,

Maharashtra, Karnataka, Andhra Pradesh, Madhya Pradesh and Orissa, while the main

river flows through only three states i.e., Maharashtra, Madhya Pradesh and Andhra

Pradesh. In the buffer area of the project, River Godavari is located towards northeast at

about 7.7 km distance from the existing project. Central Water Commission is gauging

the Godavari river discharge near Manchiryal town. The discharge varies widely from nil

in summer period to a maximum of 4475.381cumec (i.e., Cubic meter per second) during

flood period with an average of 81.131 cumec.

Jallaram vagu: The Jallaram vagu is an ephemeral tributary of Godavari river, originate

at Nallagutta, located at about 10km west of the project and flows towards northeast to

join River Godavari at Siripuram village. The drainage is of dendritic type. The catchment

area of Jallaram vagu is about 140.17 sq.km. The drainage density is 2.33 km/sq.km.

During monsoon season, the flow level of Jallaram vagu rises by 4m to 6m above bed

level and extensive areas are flooded beyond the river banks. Though Jallaram vagu is a

seasonal stream, there is a minor base flow during dry season.

Bokkala vagu: The Bokkalavagu is also an ephemeral tributary of Godavari River. It

originates from the West of Chandapalli village (near Raghavapuram) and flows easterly

and joins Godavari River near Khanapur village (Near Manthani). The stream

concentrates from Adriyala village and the width of the stream channel attains 85m and

at places it attains to 225m. The drainage pattern is of sub parallel type. The catchment

area of Bokkalavagu is about 262 Sq.km. and the drainage density is 2.5 km/sq.km.

Tanks: There are number of major and minor irrigation tanks strewn over the buffer

zone. Ex: Jangaon tank (42.3 Ha), Sundilla tank (19.4 Ha), Gaddampalli tank,

Narsimhulapalli tank, Guddelugulapalli, Begumpet cheruvu (60.9 Ha) Gundaram

Cheruvu (77.7 Ha) etc. About 15.18 Sq.km area is occupied by small & big tanks. These

tanks in turn drain into Godavari River after meeting the surrounding area agricultural

requirement.

Groundwater Potentiality: Groundwater occurs in both water table and semi-confined

conditions in the buffer zone of the project area. On the western part, ground water

occurs in the water table conditions in the geological units such as Archeans and Pakhal


58

& Sullavai group of formations. Whereas, in the north and eastern side it occurs in water

table as well as semi-confined conditions in the sand stones of Gondwana formations.

SCCL is monitoring the attitude of phreatic surface in this area, on long-term basis

periodically from 1997. The pre-monsoon and post-monsoon ground water levels are

monitored in 29 observation wells located within 10 km distance from the project. It

varies over a wide range from 1.93 to 13.40 m during pre-monsoon period and 0.83 to

11.70 m during post-monsoon period. The water level fluctuation is 0.94 m to 5.02 m with

a net fluctuation of 2.79 m. The depth of these shallow wells varies widely from 5.00m to

13.50 m with a diameter of 1 m to 3 m.

The attitude of piezometric surface is also being monitored in 15 piezometric wells

around the existing opencast projects located within the buffer zone. These piezometers

are located at 200 to 400 m distance from the edge of the mine. The cumulative

piezometric head in these piezometers varies from 1.93 m to 26.32 m in pre-monsoon

season and in post-monsoon season it varies from 1.47 to 24.41 m.

Within the buffer zone of the project, there are eleven coal mines in operation. The

quantum of water being pumped from these mines and its utility is furnished in table

Table-A

The surplus water from GDK 8, Vakilpalli, GDK-11 is being discharged into Jallaram

Vagu, and from GDK-10 & 10A, ALP and RG OC-I & RGOC-II the excess water is

discharged into Bokkala vagu. Also, excess water from GDK-1& 3 and GDK-2 & 2A is

being discharged into Jangaon and Sundilla tanks. The mine water discharged into

streams/ tanks will continuously augment the ground water in this region.

Aquifer Performance Test: An Aquifer Performance Test (APT) was conducted in

GDK-10 A inc., by constructing a well field comprising one test well and one

observation well to a depth of 270m (up to IV seam), tapping all the potential aquifers.

The depth to the water in the test well was 12.08 m. The test was conducted at a

constant discharge of 560 lit. /min. (806.4 m3 per day).

The maximum draw down recorded was 51.39 m in the test well and 4.39 m in

observation well. From this test data, the hydraulic parameters were estimated as:

Transmissivity : 40.0 m2/ day

Hydraulic Conductivity :1.67 x 10-1 m/day.

Storativity : 1.1 x10-3


59

The above data indicates that the aquifer system is of non-steady leaky type.

GROUND WATER RESOURCE ESTIMATION: Rainfall is the major source of

recharge in this area, besides a number of streams and tanks. Groundwater budgeting

of the buffer zone area is done as per GEC-1997 methodology.

I. CURRENT GROSS GROUND WATER DRAFT

a. Domestic consumption : As per 2011 census the population of this area is

2,98,864. Of this, 2,14,883 people living in urban areas (ex. Ramagundam, Raidandi,

Kundanpalli, etc,) the urban population is provided with protected water supply. The

rural population (i.e. excluding villages having protected water supply) will be 91,747 as

per the projection by 2025 AD at the growth rate of 1.06% (Source of information:

National Commission of Population annually) for Andhra Pradesh. It is presumed that

they draw ground water through open/ bore wells for their domestic needs. At the per

capita consumption rate of 60 lit./day, as per GEC-97 procedure, this amounts to 5,505

m3/day or 2.0 M.Cu.m/year.

b. Agricultural requirement: In buffer zone of Project, out of the total cultivable

area, Paddy is being irrigated in an area of 2,143 ha during kharif season and 2704 in

Rabi season utilising ground water. Additionally an area of 4793 ha in kharif season

and 1142 ha in Rabi season is being irrigated by using surface water (source: A.P.

Agricultural census data), as detailed below:

Season Source of water

Surface water Groundwater

Kharif (Ha) 4793 2143

Rabi (Ha) 1142 2704

Total (Ha) 5935 4847

Its water requirement is to the extent of 105 cm at the rate of 6 to 7 wettings. The utility

of groundwater works out to:

105 cm x 4847 ha = 5099.85 ha meters or 50.99 M.Cu.m / year.

c. Inflow of water into the coal mines: There are 11 coal mines within the buffer

zone of Adriyala Project. The quantum of water presently being pumped out from these

mines and its utilisation details are shown in following table.

The total water pumped from the above mines is 40878 m3/ day or 14.92 M.Cu.m / year.

Thus the total ground water draft in this area is:

Domestic consumption:

for rural population in buffer zone 2.00 M.Cu.m/Year

Cattle consumption 0.20 M.Cu.m/Year

Agricultural requirement 50.99 M.Cu.m/Year

Pumpage of water from Coal mines 14.92 M.Cu.m/Year

Total 68.11 M.Cu.m/Year

II. RECHARGE

1 A. Recharge from water table fluctuation : SCCL is monitoring the attitude of

phreatic surface in this area since 1997, on long-term basis periodically. The pre-

monsoon and post-monsoon ground water levels are monitored in 29 observation wells

located within the buffer zone. It varies over a wide range from 1.93m to 13.40m during

pre-monsoon period and 0.83m to 11.70m during post–monsoon period. The water level

fluctuation is 0.94m to 5.02m with a net fluctuation of 2.79m. The hilly area of 50.35 sq.

km. is not considered in the estimation of groundwater recharge.

Recharge = Geographical Area X water table fluctuation X sp. Yield.

= 389.25 sq. Km. x 2.79 m x 0.03

= 32.58 M.Cu.m / Year.

1 B. Recharge from rainfall: The mean annual rainfall of this area is 1196.97 mm, within

the buffer zone of Adriyala project, 213.97 sq.km is underlain by sedimentary formations,


61

while the rest of 225.63 sq. km. is underlain by hard rock. Within the hard rock terrain, the

hilly area is about 50.35 sq. km. This area is not considered in groundwater recharge

estimation.

Within the buffer zone of the Project:

i. Recharge in sedimentary terrain (of semi-consolidated sandstone formation):

= 213.97 sq. km. x 12% of rainfall = 30.73 M.Cu.m / Year

ii. Recharge in hard rock terrain:

= 175.28 sq. km. x 11% of rainfall = 23.07 M.Cu.m / Year

Recharge from rainfall in the buffer zone of Project (i+ii) = 53.80 M.Cu.m / Year

Comparison of recharge:

A. Recharge from water table fluctuation method = 32.58 M.Cu.m/ Year

B. Recharge from Rainfall infiltration method = 53.80 M.Cu.m/ Year

Percentage of deviation (PD) = ((A-B)/B) X100

= ((32.58 -53.80)/ 53.80) X100 = -39.44%

Since the Percentage of deviation (-39.44%) is < -20%, the Recharge estimated by

Rainfall infiltration method, is multiplied by 0.8

= 53.80 X0.8 = 43.04 M.Cu.m/ Year

2. Recharge from other sources

a. Recharge from return flow of surface water applied for irrigation :

= 40% of (105cm X 5935 ha) = 24.92M.Cu.m / Year

b. Recharge from return flow of groundwater applied for irrigation:

= 35% of (105cm X 4847 ha) = 17.81M.Cu.m / Year

c. Recharge from Return flow of mine water let out into streams:

= 20% of (8.29 M.Cu.m / Year) = 1.66 M.Cu.m / Year

d. Recharge from Godavari River flood prone area and tanks & ponds):

This is estimated based on the average area of water spread and 1.4mm/day

recharge rate for the period in which the flood prone area/tank has water. In the

buffer zone, an area of about 14.73 sq.km and 15.18 sq.km (29.91 sq.km) is covered


62

by R. Godavari and tanks respectively. As the average area of water spread is not

available, 60% of the maximum water spread is used.

Recharge from the river = 60% of 14.73 sq.km x 1.4 mm/day (120days)

= 1.48 M.Cu.m / Year

Recharge from tanks= 60% of 15.18 sq.km x 1.4 mm/day (180days)

= 1.53 M.Cu.m / Year

Total Recharge from other sources (a+b+c+d) = 47.40 M.Cu.m / Year

Gross recharge = Recharge from rainfall + Recharge from other sources.

= 43.04 +47.40 = 90.44 M.Cu.m / Year

III. GROUNDWATER ALLOCATION FOR DOMESTIC AND INDUSTRIAL USE

For the domestic use of population within buffer zone of Adriyala Project, projected by the

year 2025, an allocation of 5,505 m3/day or 2.0 M.Cu.m /year of groundwater is made.

Major industry i.e., NTPC located within the buffer zone area is meeting its water

requirement from R. Godavari.

IV. TREND OF PHREATIC SURFACE: The pre-monsoon and post-monsoon trends of

phreatic surface in the observation wells located in the buffer zone area of the project are

shown in the enclosed hydrographs (Figure-3).

V. NET ANNUAL GROUNDWATER AVAILABILITY FOR FUTURE USE: This is

calculated by deducting 10% of total groundwater resources towards unaccounted losses,

from the gross groundwater recharge as:

= 90.44 – 9.04 = 81.40 M.Cu.m / year

VI. CURRENT STAGE OF GROUND WATER DEVELOPMENT:

The gross annual groundwater availability within buffer zone area is arrived at by adding

recharge from 1) rain fall and 2) Recharge from other sources. This amounts to 90.44

M.Cu.m/Year. After deducting unaccounted losses (10% of gross recharge) the net

available groundwater is 81.40 M.Cu.m/ year. The current annual gross groundwater draft

for all uses of this area is 68.11 M.Cu.m/Year. This leaves a net surplus of 13.29 M.Cu.m

/ year.

= (68.11/81.40)X100 =83.67%.

Stage of groundwater development = Current annual gross ground water draft X100

Net groundwater available


63

VII. CATEGORISATION OF AREA FOR GROUND WATER DEVELOPMENT

As per GEC 97, areas where ground water resource assessment shows stage of

ground water development more than 70%, but less than 90%, and either pre monsoon or

post monsoon ground water level shows a significant long term decline.

The present stage of ground water development within 10 km buffer area of Adriyala

Project is 83.67%. The trend of the phreatic surface in this area is showing marginal

decline. Based on this data, this area is categorised as “Semi Critical”.

Summary:

Gross ground water recharge: 90.44 M.Cu.m/ year

Un-accounted losses 9.04 M.Cu.m/ year

Net ground water available: 81.40 M.Cu.m/ year

Net ground water draft: 68.11 M.Cu.m/ year

Balance groundwater available: 13.29 M.Cu.m/ year

Stage of groundwater development: 83.67%

Categorisation of area: “Semi Critical”.

3. Ground water seepage from the aquifers into I seam workings:

In view of annexing block A& B property of GDK-10 Inc.(i.e., rise side) to RG OC-I, the

recharging area of the aquifers exposing in Adriyala LW project is already excavated in

RGOC-I Project. Besides this, the goaf areas of already excavated longwall panels of

GDK -10A Inc. (i.e., located rise side of Adriyala LW-1 panel) has also reduced the

aquifer storage significantly. Hence I seam roof aquifer is being recharged only lateral

conductivity. Considering the stabilized inflow of 450 gpm from 3A to 3E longwall goafs, it

is opined that the clay horizon separating Barakar Fm. and Barren measures retarding

the extension of cracks resulted the caving of roof rocks. Hence, the inflow of water into

the Adriyala LW was calculated by considering the thickness from I seam roof to BM/B

(i.e., 45m).

Average depth to I seam =445m (40m aquicludes/aquitards) Depth of water level = 15m Hydraulic head (h) up to I seam 45m Av. Transmissivity (KD) = 40 m2/day Hydraulic conductivity upto I seam is 2.67 x 10-1 m/day. Av. Storativity = 1.1 x 10-3

Rate of mine expansion R = 2500 m2/day Ground water flow into I seam workings: Q1 = SRh = 1.1x 10-3 x 2500 x 45 = 123.75 m3/day. Q2= 2πKh2/ W(Uo)

U = SR/4πKD = 5.47 x 10-3 Hence, W(U0) = 1.869

= (2 x 3.14x 2.67 x 10-1 x45 x 45)/ (1.869) Q2 = 3395.45 m3/day. Q = Q1 +Q2 = 123.75 + 3395.45= 3519.2 m3/day. Q = 2445 GPM

IMPACT ON SURFACE WATER REGIME:

The Bokkala vagu and SRSP canal are flowing adjacent and above the mine take area.

Were ever the Bokkala vagu and SRSP canal crossing the mine take area will be diverted

as per the recommendations suggested by ICAD department. While diverting the stream

following precautions viz, prevailing stream gradient will be maintained, stream catchment

will not be disturbed etc,.


66

The excess mine seepage water will be pumped out & discharged into settling tanks

where the coal fines will be settled and only clear water will be discharged into the

Bokkalavagu and will be utilized in irrigation purposes for the downstream users.

IMPACT ON GROUNDWATER REGIME

The impact of mining on local ground water regime depends on various parameters like

method of mining, depth and rate of expansion, ground water recharge and hydraulic

parameters of the aquifers system of the area. In underground mining, the aquifer lying in

the immediate roof of the working coal seam contributes major inflow and gets affected.

Due to the presence of a number of impermeable strata overlying the working seams

(such as clay, shale and coal beds), the impact on the phreatic aquifer at shallow depth

will be negligible.

In view of wider and longer longwall panels proposed in Adriyala Longwall project,

detailed and comprehensive investigations were carried out in the project. As advised by

CSIRO, Australia insitu permeability and insitu stress measurements were carried in this

project. Various numerical modelling studies were also carried out for prediction of

subsidence and its extent. The studies reveled that the subsidence will not propagate to

the surface. Hence the aquifer system will not get affected due to mining.

The phreatic level varies in pre-monsoon season from 1.93m to 13.40m and in post-

monsoon it varies from 0.83m to 11.70m. In this area, the mine workings progressed far

beyond the locations of these observation wells. Due to sand stowing of the void space,

the ground water levels are stabilized.

The attitude of phreatic surface is being monitored in 53 phreatic wells in the buffer zone

area for the last 15 years. Also the piezometric surface is being monitored 21 specifically

constructed piezometric wells in the buffer zone. These wells are located at a distance of

100m to 7.5 km from the coal mines in operation. This monitoring is aimed at studying the

impact of coal mining on ground water regime, if any.

Mitigative measures:

As per the Groundwater Resource Estimation, the present stage of groundwater

development is 83.67% and the area is categorised as “semi critical”.

The total groundwater draft in the buffer area is about 68.11 M.Cu.m/Year. Of this, from

mines it is about 14.92 M.Cu.m/Year and cultivation requirements is about 50.99

M.Cu.m/Year. From the agriculture census records, it is observed that in the buffer area

of the project, the land irrigated during 2006-2007 with ground water was about 1126 ha

and during 2011-12 land irrigated by ground water is 4847 ha. This resulted increase in


67

ground water draft from about 13.51 M.Cu.m/year to 50.99 M.Cu.m/year. In the same

period the pumping of water from coal mines in the buffer area has come down from

26.45 M.Cu.m/year to 17.91 M.Cu.m/year. If the same rate of ground water draft towards

agricultural requirement continues, it may lead to fall in critical category.

Keeping in view of the above and consciousness towards corporate social responsibility,

it is suggested to take up ground water recharge measures to the tune of

20M.Cu.m/Year. Most of the coalmines are located on the eastern side of the buffer

zone. Hence, construction of artificial recharge structures for augmenting ground water

recharge is to be taken up in the western side of the buffer zone. The roof top water

harvesting is to be carried out in SCCL colonies where ever the large extent of roof tops

are available viz., Office buildings, community recreation centres, housing complexes

etc.,. It is also suggested that, awareness on optimum utilisation of groundwater resource

among the people has to be inculcated by enhancing their knowledge on consumptive

use of different irrigation methods.

While diverting the Bokkala vagu and SRSP canals which are flowing adjacent and above

the mine take area. A comprehensive study has to be made for any diversion of stream or

nallahs over mine take areas. The stream alignment, gradients are to be maintained and

simultaneously the total catchment water has to flow through the proposed diversion.

While diverting the streams or Nallahs SCCL will adhere to the recommendations

suggested by ICAD department.

The attitude of phreatic surface is being monitored in 53 observation wells in the buffer

zone of projects area for the last 17 years. These wells are located at a distance of 500 m

to 6 km from the existing coal mines. Around the existing open cast coal mines in the

buffer area, 21 Piezometric wells were constructed at a distance of 50 to 400m from the

edge of the mines. In these wells the attitude of piezometric surface is being monitored on

long term basis since 2009. This monitoring is aimed at studying the impact of coal

mining on ground water regime, if any, so that measures to mitigate it can be

implemented. As on date, no considerable impact of coal mining on ground water regime

is recorded.

Conclusion: From the long term monitoring of Phreatic and Piezometric levels at various

distances from existing coal mines, it is observed that, there is no considerable impact of

mining on water regime in this area.

Based on hydrogeological investigations carried out at various coal mines and from the

present studies, it is suggested to take up ground water recharge measures to bring back


68

the area in to “safe category”. For this, suitable water conservation measures and artificial

groundwater recharge methods shall be taken up with the advice of A.P. State Ground

Water Department.

Presently, the surplus water from the existing mine in the buffer area is being discharged

into nearby streams / tanks, which is being utilised by the local people to meet their

agricultural needs which in turn augment the recharge of ground water regime of the

area.

In view of the above, it can be inferred that there will be no further impact on water regime

in this area. However, the monitoring of phreatic and piezometric levels around the

existing and proposed mines periodically on long term basis will be continued to observe

the mining impact on ground water if any.

The following mitigative measures for water pollution control are proposed:

Normally the mine discharge water will be re-utilized for dust suppression, drinking,

domestic, washing at workshop, green belt development, etc. the surplus water will

be discharged only after necessary treatment.

There will not be any additional diversion proposal in the expansion operation. The

diverted Bokkala vagu will be confluence in the original course outside the mine

boundary.

Garland drains along the boundary of the panels will be made and the catchments

will be joined to the Bokkala Vagu.

Well drainage system was maintained at septic tank, soak pits followed by oxidation

pond. The quality of the treated effluent from the oxidation pond is regularly

monitored, which will finally joins the vagu flowing adjacent to it. Regular cleaning of

septic tanks soak pits and periodical cleaning of sludge from the natural oxidation

pond taken up for effective function of the same.

The effluent from the workshop will be treated in the Effluent Treatment Plant (Oil &

Grease Trap)

Rain water harvesting measures will be taken to augment the ground water in

addition to the summer storage tank existing at RG OC-II Project.


69

The compliance of ground water clearance conditions are as follows:

CONDITIONS COMPLIANCE

Pumped out water from the proposed project

should be diverted to bokkala vagu i.e.,

about ½ km west of the shaft. Before leaving

the water into Bokkalavagu it should be

diverted through a series of settling ponds.

Water is being allowed in settling ponds

before discharging into Bokkalavagu.

Periodic monitoring of ground water levels

and quality should be undertaken and report

must be submit to the Deputy Director,

Ground Water Department, Karimnagar.

Ground water level monitoring is being

taken up four times a year season wise

by SCCL Exploration Dept. The report is

being submitted regularly to the Director,

Ground water Department, Karimangar

Green belt should be developed in about 5

acres around the service buildings and mine

area.

Extensive Plantation is being taken up in

the adjacent vacant land, OC dumps etc.

Plantation in an area of 5 Acs as

stipulated by Ground water department

completed with native species

Provision should be made to maintain the

present use/supply of ground water in

around the project area and its restoration

due to any adverse effect of mining, in

future.

Summer storage tank, Rain water

harvesting structures were established in

the surrounding area.

Precautions should be taken to prevent

polluting of the local surface and

groundwater.

The mine seepage water is pumped out

after settling of the suspended solids in

U/G sumps. On the surface the water is

purified in the filter beds.

4.4. Impact on noise

The existing noise level in the proposed project core zone and buffer zone is as

measured is below prescribed standards. The anticipated noise levels are based on the

prevailing noise levels measured at the project site. As the mining operations are carried

out in underground, there will not be any significant impact on the existing noise levels.

The only increase in noise levels could be due to coal dispatch arrangements and surface

mine ventilation fan. Developing a green belt around the fan house and the project site

will suitably abate the noise so generated. Hence, there will not be any persistent impact

on the surrounding environment due to noise. As the mining operations are carried out in

underground, there will not be impact due to blasting and vibrations. However due to


70

increase in production the noise due to surface coal handling and coal transportation

outside the ML area will increase.

Mitigative Measures:

The main mechanical ventilator was provided with suitable evasee to dampen the

noise and no additional mechanical ventilator is required for expansion operation as

the present mechanical ventilator is capable of supplying quantity required for

additional production also.

Height of fall would be minimized at all coal transfer points and internal lining will also

reduce the impact on sides of receiving hopers and their by noise.

The transportation from the pit head to RG OC-I CHP is proposed with belt conveyor

and from RG OC-I CHP to customers by rail, so that that the noise level will be

minimum compared to any other transport system.

To dampen the noise levels along the belt conveyor impact rollers are provided at

transfer points to reduce the noise.

Ear muffs or ear plugs or any other suitable protective equipment would be provided

to workmen working in the high noise intensity areas both at surface and

underground.

Besides carrying regular periodic health check up of the workers, 10% of the workers

identified from the workforce engaged in active mining operations i.e. longwall crew,

trunk and gate roadway crew, etc., would be subjected to health check up for

occupational disease and hearing impairment through the doctors trained as per the

ILO guidelines in the company hospital.

Green belt around the fan house and mine premises was already developed in the

area. The green belt will be maintained and further developed in the area and this

will further reduce the noise.

Avenue plantation along the approach roads.

Regular maintenance of surface machinery and transportation vehicles to reduce

noise levels.

4.5. SUBSIDENCE PREDICTION

The predominant effect on land environment would be due to subsidence caused by the

underground mining. As such, subsidence prediction will be useful for determination of i)

The productivity of the land is going to be effected, ii) there could be change in drainage

pattern and depletion of the ground water iii) there could be damage to the vegetation


71

over the mine take area iv) Fire may occur in coal seams due to the leakage of air

through cracks formed due to subsidence causing air pollution.

However, it is possible to minimize the damage to the surface land by careful planning

and design of the underground workings as well as maximizing the coal recovery. In this

connection, during 2004, the subsidence prediction study using 3D Numerical Modeling

was carried for the production capacity of 2.144 MTPA in the block area of 340 Ha. As

per the study, the mining operations were divided into seven blocks of 5 year interval over

the life of 35 years.

As the production capacity is proposed to increase from the 2.144 MTPA to 3.14 MTPA,

the subsidence prediction study using 3D Numerical Modeling is carried for the same

mining block with the production capacity of 3.14 MTPA. As the rated capacity increased,

the time blocks were reduced from seven to five. The details of the study and impact of

the subsidence on various surface structures for the rated capacity 2.144 MTPA Vs 3.14

MTPA is presented herewith:

Objective: To evaluate the subsidence and the other effects on surface features and

village due to working 250m face length Longwall panels in Adriyala Shaft Project at RG

III area.

Geology: The proposed Adriyala Shaft Project extends from the north of Bokkala vagu

up to Fault F4. The regional strike of the deposit is more or less NNW-SSE. The

gradient of beds varies between 1 in 6.00 to 1 in 7.8. The block is virgin and contains

seven seams, viz., IA, I, II, IIIB, IIIA, III and IV in descending order. The depth of bottom-

most IV seam varies from 406 m to 644 m. Out of the above seven seams, only four

seams have attained workable thickness and are persistent. The generalized sequence

of coal seams, their parting and thickness in the proposed block is given in Table 1.

Proposed Mining Method: Due to high depth of occurrence of the seams, simple

geological structure and medium thickness of the seams, mechanical Longwall

technology in the descending order has been proposed for all the four mineable seams of

the block. I, II and IV seams are proposed to be extracted in single section, whereas, III

seam is proposed to be extracted in two sections – one along roof and the other along

floor. All the proposed seams are under extraction by Longwall technology in the

adjoining mines of GDK-10A and GDK-9 inclines. There has not been any serious

problem of the roof cavability in these mines; hence, no problems of caving are envisaged

in the block. As the depth of seam is beyond 400 m, it is proposed to access the seams

through shaft and existing roadways through inclines of the GDK-10A mine. The

proposed two shafts, one intake (man winding) and the other return will serve for the

access to the coal seam and for the ventilation, respectively.

Period of Prediction: The detailed time period, for the prediction of subsidence required,

is 20 years, at an interval of 5 years.

Stage – I 5 years

Stage – II 10 years

Stage – III 15 years

Stage – IV 20 years

Simulation for Prediction: The natural mining has to be simulated before it can lend

itself to the numerical modeling. As the first step, Fig. 1 is a simulated grid map of the

proposed mining area of the Adriyala Shaft in terms of contours of the surface profile.

Fig. 2, 3, 4, 5 and 6 are the simulated grid maps of the workings of the Seams-I, II, III top,

III bottom and IV. The simulated mine plan has a scale of 1:5000, same as that provided

by the mining company. Various types of hatchings of the panels in these maps portray

the sequence of mining operations in the 5 years time block. The prediction of subsidence

and the resulting surface is, therefore, confined to 5, 10, 15 and 20 years of mining. Table

4 gives the coordinates of few boreholes on the simulated grid maps, which can be used

for the studying, and the analyzing of all the maps provided by us.

Requisite Geotechnical Parameters for the Prediction: The numerical prediction of

subsidence requires basic data 1) Geotechnical parameters of the seam and surrounding

rock mass upto the surface, 2) Mathematical model and computer programs (software)

3) Major structural features of the strata, 4) Details of the mine excavation 5) Sequence

of extraction and size of panels, and 6) Important features on the surface. The

information on the above mentioned parameters were provided by the company. The

company also provided the data for the physico-mechanical properties used in the

simulation. The above properties were taken for various panels as per their proximity to

the above boreholes in the block. The boreholes nearest to the panels were considered

to be representative one and hence selected for the simulation.

Prediction Technique: The computer-simulated model was developed for the prediction

of subsidence and alterations in the resulting profile of the surface, keeping in mind the

total area, the mining sequence and geo-technical properties and above all, depth of each

mining panel, which varies significantly from panel to panel and seam to seam. The grid


75

map for simulation is based on 25 m grid on the surface having about 8000 points for

calculation process using finite element method (FEM) – a numerical simulation

technique. The computation for prediction of subsidence of the area is based on the grid

pattern. The 3-D mathematical model, thus simulated was subjected to the finite element

analysis. The model also takes care of the non-linear behaviour of the rock mass (if any),

bed separation and its re-contact.

Predicted Subsidence Contours: Fig. 7 shows the subsidence contours after 5 years of

mining. Similarly, Fig. 8 through 10 give the subsidence contours at the end of 10, 15

and 20 years of mining, respectively. The maximum values of the subsidence predicted

at the end of each time blocks are given in Table 5.

4. 20 -1.328

To illustrate an overall picture, a few subsidence values along with coordinates on the

simulated grid maps for various time blocks of mining have also been summarized in the

Appendix in the Tables I to IV.

Three Dimensional Projections of Subsidence: To give a 3-dimensional impact of the

subsidence, the predicted subsidence has been projected on the surface for each of the

mining periods based on x and y coordinate defining the horizontal plane and ‘Z’

coordinate, the depth of the surface. It may be noted that the ‘Z’ coordinate has been

exaggerated (25 times) to have a better visual appreciation of the impact of subsidence.

Figs. 11 through 14 give prediction of the subsidence at the end of 5, 10 15 and 20 years

of mining respectively, considering the surface to be horizontal, before

These figures give a real feel of the impact of subsidence as a result of the multi seam

mining and the progression of mining with time. Two sets of subsidence figures are

provided for each stage. These are having opposite viewing directions, i.e. 45o and 225o.

It may be pointed out at this stage that the 3-dimensional projections shown in the figures

11 through 14 should not be used to pin point the maximum subsidence area because all

the points may not be visible on the map. However, these drawings provide fairly

accurate idea about ground behavior after mining. It is worth noting that the troughs

shown in the figures should be viewed in the proper perspective as the scale in ‘Z’

direction has been enlarged to 25 times to have appreciable viewing impact.

SURFACE PROFILE: The surface profiles of the mining block after each stage of mining

have been predicted. These profiles have been obtained by superimposing subsidence

with premining surface profile after each mining sequence for different time blocks. Fig. 1


80

gives the surface profile of the mining block before mining. The contour maps which

would finally emerge as a result of mining after 5, 10, 15 and 20 years have been

predicted and is shown in Figs. 15 through 18. It may be observed that the effect of

subsidence on surface will be insignificant even after the mining of 20 years.

Fig.19 shows the 3-dimensional prediction of subsidence before mining for the

Adriyala Shaft. Figs. 20 through 23 gives the 3-dimensional prediction of surface at the

end of each mining sequence (the ‘Z’ axis has been exaggerated to 10 times for having

better visual appearance of the impact of subsidence). A set of figures showing surface

subsidence and surface profile at the end of 5, 10, 15 and 20 years of mining is also

being provided in larger sizes at a scale of 1: 5000. The surface contours along with the

panels of the seam-I, II, III top, III bottom and IV are also being provided in larger sizes

i.e., at a scale of 1:5000.

Maximum Tensile Strain: Maximum predicted tensile strain for Adriyala Project at

various time blocks has been given in the Table 6.

Table 6. Predicted value for the maximum tensile strain in forest area for Adriyala Project

at various time block

Sl. No. Time Block Tensile Strain mm/m

1. 5 3.5

2. 10 4.5

3. 15 5.3

4. 20 6.5

The predicted maximum tensile strain at the end of 5 years of mining is 3.5 mm/m. The

maximum tensile strain increases slightly with time. It increases to 4.5 mm/m at the end of

10 years of mining, 5.3 mm/m at the end of 15 years of mining and 6.5 mm/m at the end

of 20 years of mining.

Crack Width: It is well known from the field experience that the cracks may occur under

the condition of high tension and weak rocks. The prediction of crack width is associated

with high degree of uncertainty. Zones of possible cracks will lie in the vicinity of weak

rocks and near fault planes under large tensile strain. To have accurate predictions, the

strain maps should be superimposed over the detailed geological plan and geotechnical

data. Cracks of significant width are not likely to be formed.

The maximum subsidence predicted during the various time blocks as per the

earlier rate of productions with 150 m face length and production capacity 2.144

MTPA are as follows:

Sl. No Year Subsidence Values in m

1 5 -0.104

2 10 -0.335

3 15 -0.451

4 20 -0.814

5 25 -0.935

6 30 -1.077

7 35 -1.077

Analysis: Fig. 7 depicts the surface subsidence contours at the end of 5 years of mining.

The area of the surface undergoing subsidence is situated in the middle. The maximum

predicted value of the subsidence is –0.865m, occurring in a time span of 5 years. It

shows just one shallow gentle trough. The subsidence trough at the end of 10 years of

mining is slightly enlarged in area. Maximum subsidence at this time would be –1.073 m.

The area of this trough slightly increases in extent at the end of 15 years of mining. The

point to be noted is the formation of only one uniform and gentle trough, which is very

shallow with maximum subsidence of –1.183m.


86

The block under the influence of subsidence at the end of 20 years of mining is, by and

same as the earlier one having slightly large, higher subsidence magnitude. The peck

subsidence at the end of 20 years of mining has been predicted as -1.328m.

It may conclude, based on above and examination of surface structures that a large,

shallow and gentle trough will be formed at the end of 5 years of mining. This through will

increase in size and depth marginally with time. Moreover, there is no likelihood of

formation of multiple troughs. The maximum tensile strain has also been predicted of low

magnitude. Therefore, no significant damage is likely to occur on the surface.

Effect of Subsidence on Adriyala Village: The Adriyala village lies outside the

subsidence trough at the end of 5 years of mining. However, the village may experience

subsidence of 0.5 m at the end of 10 years of mining. The magnitude of the subsidence

will slightly increase at the end of 15 and 20 years of mining. Some part of the village may

experience the subsidence up to 1.0 m at the end of mining. The subsidence trough is

large and gentle. Therefore, no crack is likely to occur in the village structures. Moreover,

the tensile strain experienced by structure in the village is not likely to more than 3 mm/m.

The village will lie within the compressive strain zone. Therefore, no crack is likely to

occur in field or structures. However, care should be taken of mud structures and Katcha

houses.

However, the village area is earmarked for dumping of Over Burden generated from RG

OC-II Expansion Project for which Environmental Clearance was granted in 2010. As

such, the Rachapalli Village is proposed to Rehabilitate to outside the ML area.

Effect of Subsidence on the Protected Forest Land: At the end of 5 years of mining a

very small patch under protected forest cover will experience 0.50 m of subsidence,

which will have no effect on the forest cover. Subsequently, at the end of 10, 15 and 20

years of mining, this subsidence trough would slightly increase in size but not in

magnitude and it will have no significant impact on forest cover. The subsidence trough

covering the protected forest is small, shallow and gentle. Hence, it will not have any

significant effect on the forest cover in terms of strain, crack width and vertical

subsidence. However, the area is diverted vide F. No. 8-109/2005-FC, dated 02.05.2008

and GOMS No. 74 of EFS&T of GoAP dated 18.06.2008.

Effect of Subsidence on Bokkala Vagu: It is revealed that, there will be effect on the

original course of the Bokkala Vagu and possibility of inundation. As such, the Bokkala

Vagu is proposed to divert in the earlier proposal only. The Bokkala vagu is proposed to

divert through the area above the trunk roadways. As such, it was assessed the impact of


87

subsidence on the proposed diversion course of Bokkala Vagu also. There will not be any

effect of subsidence on proposed diverted Bokkala Vagu. A fund provision of ₹ 250.00

lakhs were made towards diversion of Bokkal Vagu. The diversion will be carried with the

permission of the I&CAD department only.

The Effect of subsidence on the Sriram Sagar Canal: Fig 7 through 10 shows that the

contour of up to 1.0 m will intersect the Sriram Sagar canal. In first five years, only a small

portion of canal will get affected. However, larges canal lengths will be covered by

subsidence trough with progression of mining with time. The maximum vertical

subsidence will be slightly more than 1.0 m at the end of mining. Therefore, the canal will

be affected most, out of all the surface features on the property, by the subsidence. The

subsidence trough formed on the surface, through which the canal passes is large,

shallow and gentle in slope. The following measures are suggested by IT BHU, Varanasi:

1) Regular monitoring of the subsidence along the canal should be done. Though, no

crack is likely to occur, however, proper monitoring should be done at the regular interval.

2) Part of the canal will experience the vertical movement. Therefore, adequate measures

should be under taken, to maintain flow of water and 3) Embankment of the canal should

gradually be increased.

In view of the impact on the SRSP Canal, it is proposed to diver the canal along non-coal

bearing area for which a fund provision of ₹ 800 lakhs were made. In the earlier proposal

also it was proposed to diver the canal.

Effect of Subsidence on Crop Productivity: The total magnitude of subsidence, in 20

years of mining is slightly more than 1 m. However, a subsidence trough of about 1 m will

take place gently, gradually over a large area. Hence, its impact will not be there on crop

productivity. The subsidence trough will not alter the natural drainage pattern or land

profile significantly as evident from Figs. 11 through 14. However, the entire land on the

mine take area acquired.

4.6. Impact on Socio Economic Environment

No significant changes have been visualized in the traditional way of life and occupation

of the local people in coal mining areas. The local people are rather benefited due to the

provision of more infrastructure facilities provided by the management.

Corporate Social Responsibility The Company CSR Policies aimed

Social and Community Initiatives

SCCL is carrying out coal mining operations in the four Districts of Andhra Pradesh

namely Khammam, Warangal, Karimnagar and Adilabad. Surrounding Habitat

Assistance Programme (SHAPE), started during the year 2003-04 with a concept that

partner in progress.

The mechanism adopted to identify the community needs is very pragmatic. The local

bodies in these habitats will identify the works in association with the community and

Rural Development Agencies of the State Government. The funds are provided under

SHAPE program by the company for the Government to execute the work. Under this

programme, Drinking water supply, education facilities and infrastructure development in

the surrounding habitats of SCCL are taken-up.

Habitats which are less than 8.00 Km from townships or 10.00 Km from mine entries and

having SCCL workmen at 25% of total population or 200 Nos., whichever is less are

generally considered.

About 15 Lakhs population in nearly 81 Gram Panchayaths, 7 Municipalities and the

District Administration of 4 Districts in Andhra Pradesh are partners in the Community

Development Projects of “SHAPE” launched by SCCL. Modalities of the developmental

work are being finalized in consultation with District Collectors and Peoples

representatives (Sarapanch, Village Chief etc.).

About 229 works in Adilabad, 221 works in Karimnagar, 101 works in Warangal and 327

woks in Khammam districts are taken up such as protected drinking water supply,

education facilities and infrastructure development in the surrounding habitats of SCCL.

The following CSR Works were already taken up in Buffer zone of the Project area:
