General Overview2009 has been a year of continuing growth at the Chair

of Mining Engineering & Mineral Economics. Despite the

economical downturn in the industry, research and

development activities in the field of mining increased.

These comprise both fundamental research activities as

well as applied research activities sponsored by the

industry. The economical performance of the Chair in

2009 was positive. The total budget amounted to

around 1.600.000 €: out of this round 750.000 €

came from the University Resources. The income from

own research activities (industry and the European

Union) was around 850.000 €.

Industrial sponsored research and development

activities could be increased by 20 % in comparison to

2008 and now are twice as what they have been by the

end of 2007. Parallel to the increase of the activities

also the number of employees at the department went

up from 27 into 2008 to 35 by the end of 2009.

Despite a lot of investment into equipment for field work,

the cash reserves could be increased to around

550.000 € by the end of 2009. So the Chair of Mining

Engineering & Mineral Economics has currently a quite

sound financial basis, which is planned to be further

broadened in 2010.

The Chair of Mining Engineering & Mineral Economics is

proud to report, that despite a lot of field research

activities the year 2009 was free of accidents.

Programs were realised to further improve the safety at

work place. All employees got first aid training. New

activities with respect to mine safety were also started in

the frame of the regular study programs in mining: For

the first time a practical mine rescue training was

offered to the mining students in cooperation with the

Austrian Centre for Mine Rescue and Gas Defense.

The Chair of Mining Engineering & Mineral Economics

has been participating since 1992 in European Union

financed research projects, comprising currently the EU

research project SARMa, to which the Chair has

successfu l l y contr ibuted dur ing 2009 with

investigations into the “Sustainable Resource

Management”.

As remarkable international project activities the

engagement of the Chair of Mining Engineering &

Mineral Economics in the planning of the extension of

the underground chrome mine Bulqiza in Albania and the

development of the underground talc mine Rodoretto in

Italy has to be mentioned. The same is true for the large

amount of work done in cooperation with Rio Tinto

Minerals, especially with establishing a Centre of

Excellence for Rock Blasting and the work done in the

open pit talc mine Trimouns in France.

On a domestic and European level the Chair had

successful R&D cooperations with companies like

Sandvik, RHI, Omya, Holcim, Strabag, Trumer

Schutzbauten, 3G Measurement, DCM DECOmetal,

Alpine, Styromag, LKAB, Atlas Copco, Austin Powder,

Dolomitwerke Neuper, VA Erzberg and many other small

and medium sized Mining and Construction companies.

A special thank goes to all of them for their continued

support of the Chair.

Annual Report 2009 3

As one of the founding member of the European

Technology Platform for Sustainable Mineral Resources,

the Chair of Mining Engineering & Mineral Economics is

also engaged with political and technical issues for a

future sustainable supply of Europe with minerals from

domestic resources.

The Chair of Mining Engineering & Mineral Economics

continued to support the Association of Austrian Mining

Engineers (Bergmännischer Verband) by providing a half

time academic person for the organisation of the annual

meetings and activities .

In 2009 the Chair of Mining Engineering & Mineral

Economics continued to receive royalties from a patent

for photogrammetric surveying equipment (in

cooperation with 3G Measurement & Software and

Strabag).

The number of master students graduating from the

university is growing as well. In 2007 5 students get

their degree in mining, 5 in 2008 and 7 in 2009. The

long term planning for the number of mining engineers

graduating is currently set at around 15. The number of

PhD students registered at the Chair of Mining

Engineering & Mineral Economics is now for the first

time above 20 (see list of PhD's in preparation).

Postgraduate training activities remained high in 2009.

This year not only saw the graduation of the first 19

International Mining Engineers but also an extension of

the International Mining School activities into

International Mining and Construction. Explosives

engineering and mine safety postgraduate courses were

held as well.

To honour the generous contributions of Sandvik Mining

and Construction for both training and research &

development it was decided to award the title of a “Miner

of Honour of the Chair of Mining Engineering & Mineral

Economics” to the president of Sandvik Mining and

Construction, Lars Josefsson.

On the 26 th of February 2009, the Chair of Mining

Engineering & Mineral Economics got the “Prize Award”

from the Austrian Ministry of Science and the Ministry of

Economy for the outstanding invention “Contour Blasting

System”. This award of 150,000 € allowed the further

development of the patented bulk explosives contour

blasting system from prototype to field testing.

In terms of fundamental research work, the year 2009

brought the start of activities in the field of new rock

breaking technologies as alternatives to drilling and

blasting. In that respect especially microwaves are

tested as an alternative way of breaking hard rock. First

plans were developed to start also research activities in

the field of laser assisted rock cutting and using electric

pulses for hard rock disintegration.

Based upon a new strategic concept for research and

development in the field of rock fragmentation and

excavation engineering, the Rector of the University of

Leoben decided to allocate additional resources for

mining research to the Chair of Mining Engineering &

Mineral Economics. In addition new personal resources

were granted especially for future work in the newly built

laboratories. Around € 100,000 were invested into new

field measuring equipment.

In terms of internationalization and international

networking the Chair of Mining Engineering & Mineral

Economics worked on the future development of training

and research contacts with the St. Petersburg State

Mining Institute. Austrian delegations from the

University of Leoben and the industry were visiting St.

Petersburg and Russian Delegations were visiting both

University of Leoben, the mining equipment

manufacturers Sandvik and Binder Gleisdorf and the

company Mineral Abbau - Strabag SE.

the Sandvik factory in Zeltweg

The cooperation with the Indonesian Government and

especially the Ministry for Mines and Energy in Jakarta

was extended. Around 30 young Indonesian students

were interviewed, interested to follow PhD and master

study programs at the University of Leoben in the future.

In December 2009 the Chair Holder Peter Moser gave

the first seminar on Explosives Engineering and Rock

Fragmentation in Indonesia at the Bandong Institute of

Technology.

The international research axis of the Chair of Mining

Engineering & Mineral Economics was further developed

especially with the Centre for Geosciences of Ecole

Nationale Supérieure des Mines de Paris, SWEBREC - the

Swedish Centre of Excellence for Blast Fragmentation of

Lulea Technical University and the Esculea des Minas in

Madrid.

With the generous support of DCM Deco Metal, the

Chair of Mining Engineering & Mineral Economics could

sign an agreement for students exchange with the South

African Mineral Research Institution Mintek. From

2011 on young South African students will follow MSc

courses at Leoben University in the field of Mining and

Mineral Processing.

The year 2009 saw some remarkable steps towards the

completion of the new raw materials laboratory of the

Department in Mineral Resources and Petroleum

Engineering which will be named IZR (Impuls-Zentrum

Rohstoffe). It will be the first time that all labs of the

Department Mineral Resources and Petroleum

Engineering are united in one building, creating synergy

effects which will help to strengthen the position of the

University of Leoben as world-class research institution.

Following the commissioning of this building, which is

expected in early 2011, the IZR will be home to

research-activities of the Chair of Mining Engineering &

Mineral Economics in the following areas:

Rock mechanics in mining environmentsBackfill engineeringVentilationAlternative rock fragmentation methods

The highlight of the building will be a 10 m deep shaft

with a cross-section of 25 m². This facility, as most of

the facilities for rock engineering, is jointly operated with

the Chair of Subsurface Engineering and will be used for

large-scale testing arrangements.

an international double degree program which goes

beyond the simple exchange of students during one

semester. Students in this program start with the first

semester of the master program at the University of

Leoben. The second semester is taken at Ecole des

Mines de Paris, during the third semester the master

thesis is prepared and than the forth semester is taken

again at Ecole des Mines de Paris. The first graduated

engineer (Dipl.- Ing., MSc Anja Bechter) got her degrees

in the frame of this double degree program in July 2009

in Paris and in September 2009 at the University of

Leoben.

In 2009 the Chair of Mining Engineering & Mineral

Economics was active with changing the master

program “Mining” from a German to a full English

program. Qualified students from all over the world may

now follow an English based training program in Mining

Engineering. During 2009 students from Australia,

Portugal, Turkey and Germany participated in this new

English mining program.

To promote successful students in the field of Mining and

Processing, Rio Tinto Minerals is providing every year two

study awards, one for an outstanding student in the BSc

program Mineral Resources Engineering and one for an

outstanding student in Mining or Mineral Processing.

The Chair of Mining Engineering & Mineral Economics is

currently engaged in the following regular study

programs at University of Leoben:

¢Mining (as part of the MSc program Mining &

Tunneling)¢Raw Materials and Energy Systems (as part of the

MSc program Mining & Tunneling)¢Mineral Resources Engineering (BSc program)

Teaching is also provided for students in the field of

Applied Geology and Mineral Processing. In October

2009, 33 new students registered in the BSc study

program Mineral Resources Engineering.

During the reporting period a total of 130 semester

week hours (around 2000 net lecturing hours) was

lectured in the various training programs.

In that respect the Chair wants to thank the large

number of external lecturers helping to present this

large amount of teaching. Special thanks go to the

following external university lecturers, active in 2009: T.

Drnek, J. Friedl, F. Friesenbichler ,T. Frömmer, E.

Gaisbauer, A. Gruebler, F. Hruschka, A. Maier, A.

Maurer, T. Oberndorfer, J. Plank, G. Pollak, R. Schaffer

and M. Wurm.

The development of the registration of new students is

acceptable, but not get fully satisfying. The Chair of

Mining Engineering & Mineral Economics is thus

undertaking in cooperation with the other Chairs at the

Department Mineral Resources & Petroleum

Engineering and supported by the industry, numerous

activities to increase the number of beginners in the

Mineral study programs. Amongst others several open

days with presentations of university activities are

organised and an active participation in the Road Show

of the University (Show truck) is done.

In order to further promote the internationalization of

the mining education at Leoben University, the Chair of

Mining Engineering & Mineral Economics has been

working now since more than 20 years on cooperation

programs. Today student exchange programs exist

especially with the following universities:

¢University of New South Wales, Australia¢Colorado School of Mines, Golden, USA¢Ecole Nationale Supérieur des Mines de Paris, France¢Technical University Lulea, Sweden

In addition the University of Leoben has a large number

of Erasmus agreements with further technical

universities in Europe.

Postgraduate Training ActivitiesInternational Mining Engineer

In October 2007 the new postgraduate training

program “International Mining Engineer” was launched.

The program that was developed at the Chair of Mining

Engineering & Mineral Economics in cooperation with

Sandvik Mining & Construction is specially designed for

engineers that have no mining education, but need the

mining knowledge to be able to better understand their

customers business. The course is held in two weeks

modules spread over a period of two years together with

partner universities around the globe. The University of

Leoben is not only delivering modules, the Chair of

Mining Engineering & Mineral Economics also serves as

the program coordinator.

In October 2009 the first nineteen International Mining

Engineering students graduated from the post training

program. On that occasion an examination commission

with professors from five different universities came

together in Leoben. All 19 students successfully passed

the examination and were awarded the degree

“International Mining Engineer”.

During the second year of the training program all

students have to complete a final project work. Beside

the lectures and the laboratory exercises delivered by

the University staff and renowned senior people from

the industry, mine visits and field work are an important

part of the course and serve to emphasis even more the

importance of the practical application of the learned

knowledge.

For an extension and further promotion of tailored post

Research and Development Activities

Rock Engineering

The research and development at the Chair of Mining

Engineering & Mineral Economics is organized around

the three core activities Excavation Engineering, Rock

Engineering and Systems Engineering & Sustainable

Mineral Supply.

Research activities comprise both fundamental focused

research and applied research and in addition the

development of products for the mining and quarrying

industry.

Large part of the focused fundamental research activity

in the field of excavation engineering deals with better

understanding of the interacting between the

fragmentation process and the material properties of

the rock.

The development of new products comprises the

production of prototypes for an improved contour

blasting in underground application, both in tunnels and

stopes. The development of the photogrammetric

surveying system Blast Metrix was continued especially

with respect to a better calibration and a better system

stability.

The main academic research partners of the Chair of

Mining Engineering & Mineral Economics are the

following institutions:

Rock Fall Protection Systems

In 2009 just as the years before - the Chair of Mining

Engineering & Mineral Economics supported Trumer

Schutzbauten GmbH an Austrian producer of rock fall

and avalanche protection systems - by the development

and testing of rock fall protection kits at the Styrian

Erzberg. At the test facility “Erzberg”, which is situated

at the waste dump of the open pit mine and which is

operated by the company itself, five rock fall protection

systems were tested according the ETAG 027

successfully in 2009. Therefore a total of 20 energy

impact tests were performed under supervision of the

Chair of Mining Engineering & Mineral Economics and

the Austrian Institute of Construction Engineering (OIB).

The energy levels reached up to 3,0 MJ, which means

an impact speed of a test block of 8 t - which equates the

mass of a small truck - of 28 m/s.

Besides the performance of system tests according to the

ETAG 027, Trumer Schutzbauten GmbH started a

research and development program in close cooperation

with the Chair of Mining Engineering & Mineral Economics

in 2009.

The main objective of this program is the development of a

flexible rock fall protection system for energy impacts up to

7,5 MJ.

Within the research project, which is called Trumer

Technology 2012 and which is supported by the Austrian

Research Promotion Agency (FFG), the Chair of Mining

Engineering & Mineral Economics has a leading role in five

work packages, which are

Major target of the research work in the field of rock

engineering is the development of a better under-

standing of the reaction of rock mass on mining

activities. These comprise both the development of new

stopes and also their backfilling. Research into the

behaviour of high surface slopes is another part of the

activities as is the standardisation of backfill

characterisation.

The determination of the rock mass properties as part

of the rock engineering research activities was very

much relieved by the purchase of a fully hydraulic

diamond drill rig (Sandvik DE 110), the only one of its

kind in use in R&D in Austria.

Apart from the rock engineering research activities

which are described more in detail below, the following

activities can be reported for 2009:

Planning of new underground stopes and rock

mechanics assistance for the Breitenau and

Radenthein underground magnesite mines in

cooperation with RHI, AustriaUnderground mine planning and rock mechanics

analysis for the magnesite mine Wieser and Angerer

with Holcim, SwitzerlandRock mechanics and analysis of the underground

mining activities and backfill activities in the tungsten

Testing and Evaluation of Backfill Mixtures

The use of backfill is an important part in the sequence

of most underground mining methods. The

development, testing and evaluation in terms of meeting

the crucial parameters are again important parts in the

process of backfilling of underground voids.

An important share of the research activities of the

Chair of Mining Engineering is dedicated to evaluate the

impact of the use of backfill on the local and regional

stability of mine workings. Most of this work will be done

during a PhD-Study, focusing on the comparison of

backfill properties determined in laboratory tests to the

backfill properties in-situ. The second scope of this study

is to gain a better understanding of the interactions

between a backfill body and the surrounding rock mass.

Trumer Technology 2012 will last two years and the

second period of the project (starting in summer 2010)

will be characterised by numerical simulation of single

components with the objective of modelling the

complete system performance sometime in the future.

This part of the project is done in close cooperation with

the Institute of Mechanics at the University of Leoben

whereas the Chair of Mining Engineering & Mineral

Economics will be responsible for the performance of

field tests in order to collect data.

General aim of the research activities in the field of

excavation engineering is especially the development of

a better understanding for the fundamental laws

governing the disintegration of hard rock. These

activities comprise first rock blasting, second

mechanical excavation and third new alternative

methods for hard rock breakage. In that respect

especially microwaves are tested for hard rock

fragmentation.

The blast fragmentation research work which has been

done during the period 2000 to 2004 in the frame of a

large EU sponsored project (Less Fines) is currently

continued with respect to implementing the results of

that work into quarries and mines in Austria. New

products and tools are developed with respect to energy

controlled and particle size controlled blasting

technology. Controlling the fragmentation to reduce the

mining costs and to improve the utilization of the

resources (reduction of fines as much as possible) is a

major objective of the R&D work. As a by-product new

international standards for drill & blast work in quarries

are developed.The R&D work for the introduction of alternative

methods into hard rock fragmentation aims at

increasing the speed of mechanical hardrock cutting

and lowering the energy consumed. A lot of the work is

based on the concept of the natural breakage

characteristic of the rock. All this should help to

increase development rates in small and medium size

drifts to more quickly develop new underground deposits

in the future.

Apart from the R&D work which is explained below more

in detail, during 2009 the following project work was

carried out in the field of excavation engineering:

Development of standards for drilling, blasting and

loading in open pit mines in cooperation with Rio Tinto

MineralsOptimization of fragmentation in the underground

mine in Kiruna (Sweden) in cooperation with

Technical University of Lulea and LKABMeasurement and analysis of blast vibration in

causes thermal stresses and adjacent cracks.

Preliminary tests were performed with a 3 kW

microwave. The picture shows a sample after

irradiation. The assessment of the damage is done by

ultrasound velocity invest igat ions, computer

tomography and microscopical investigations. The

decrease in ultrasound velocity is a good indication for

Microwaves and Hard Rock

In cooperation with Sandvik Mining and Construction in

Zeltweg the possibilities of weakening rocks with the

help of microwaves are investigated. The goal is to

weaken the rock in order to make cutting in hard rocks

more feasible with roadheaders. Every mineral in a rock

Microwaves and Talc

During the reporting period the following projects in the

field of mineral engineering were carried out sponsored

by Rio Tinto Minerals:

(1) Microwave assisted comminution of talc (2) Microwave assisted enhancement of the magnetic

properties of pyrite

The interaction of mineral raw materials such as rocks,

minerals or especially sulphidic ores with microwaves is

widely studied, whereby on the one hand the heating

characteristics and on the other hand in particular the

comminution behaviour of different materials were

investigated. Thereby the application of microwaves is

limited only to materials which are not transparent for

microwaves and show a corresponding absorption

behaviour.

(1) The first project of the two microwave studies

carried out in cooperation with Rio Tinto Minerals is

dealing with the unique microwave absorption behaviour

of talc from Three Springs, Western Australia. Talc

normally has not the material properties to absorb

microwaves and is considered to be a microwave-

transparent material. However, talc from Three Springs

shows extraordinary good absorption behaviour for

microwaves and correspondingly a high heating rate.

The comminution of talc, especially the grinding to fine

particle sizes in the range of 10 microns consumes

significant amounts of energy. The target of this study

was therefore to find out, whether by means of

microwave irradiation, the microstructure of the talc

can be disaggregated accordingly, leading subsequently

to energy savings for crushing and grinding.

The experiments showed that the microwave irradiation

induces thermal stress in the talc causing clear

macroscopical cracks, which improves the comminution

behaviour with energy savings of around 20% at the

same specific surface.

(2) The second project within the scope of the

microwave studies deals with the microwave irradiation

of pyrite. Pyrite occurs very often to a greater or lesser

extent as accompanying mineral in almost all talc

mineralizations. Therefore, during processing the pyrite

has to be separated carefully, because the very

important whiteness degree of the finely ground finished

talc powder can be negatively affected by impurities of

pyrite.The aim of the present study was to investigate the

microwave induced phase transformations of pyrite into

magnetic phases like pyrrhotite and magnetite, in order

to evaluate the potential of magnetic separation of pyrite

from talc.

Both studies will be continued in 2010 in order to

evaluate the potential for an industrial scale up.

It was found that under appropriate conditions pyrite can

be transformed to magnetic phases like pyrrhotite or

magnetite which can easily be removed by magnetic

separation.

A frequently occurring problem in mining is the

assessment of the effects of surface blasting on

underground mine workings in general and workings in

abandoned mines in particular. The effects of blast

induced ground vibrations on surface structures have

been studied in great detail and documented in

guidelines and standards, i.e. DIN 4150, ÖNORM S

9020. For underground structures such guidelines do

not exist.

The purpose of the study was to create a basis for the

assessment of the effects of surface blasting operations

on underground workings. For this purpose the Chair of

Mining Engineering & Mineral Economics conducted a

literature research and monitored a number of blasts at

the Styrian Erzberg. It was found that in close proximity

to the surface blast, underground blast vibrations are

comparable to those on surface. With increasing

distance from the blast ground vibration decrease to

about one half of those experienced on surface.

Furthermore underground structures are capable of

tolerating much higher levels of ground vibration

compared to surface structures. This is due to the close

interaction between structure and the rock mass.

According to these studies the effects of surface

blasting operations on underground workings are far

less severe than expected on the basis of surface blast

experiences.

Study of the Effects of Surface Blasting Operations on Underground Mine Workings

Annual Report 2009 13

During the last four years the Chair Mining Engineering

& Mineral Economics worked together with other

European research institutions on the underground

space development project Tunconstruct (Tunnelling

Innovation in Underground Construction). This EU

project had an overall budget of more than 20 Mio.

Euros and was with 40 project partners from 11

different countries one of the world's largest so far. Its

ambitious goal was to reduce time and costs of

tunnelling project by 30 %, accidents by 50% and

minimise any noise or dust emissions in order to

increase the quality of life for the society and the

competitiveness of the European industry on the global

market.During the project time the Chair had the possibility to

work on two subprojects. One dealt with the impact of

different excavation methods (drilling and blasting

versus mechanical excavation with roadheader/TBM)

on the surrounding rock mass. This was done together

with the mining equipment supplier Sandvik Mining and

Construction. The second subproject which was done in close

cooperation with the Spanish construction company

FCC, dealing with blasting related issues. The main

research topics were the formation of ammonia in

blasting fumes, investigations into smooth blasting

systems and the measurement of vibrations from the

blast cut.

Within the framework of the investigations an

underground blasting chamber for the measurements

of blasting fumes was built and a new in-hole vibration

monitoring equipment was developed to measure

vibrations in the near field of blasts (a few meters).

In the frame of the “FFG-Innovationsscheck” program a

project with the Europe wide operating construction

company Hengl Bitustein Straßenbaustoffe GmbH was

launched. The company was interested in evaluating the

possibilities of a better prediction of their blast

vibrations around their quarries. Therefore a first field

test was set up in the village of Eibenstein where the

company operates one of their four quarries in Lower

Austria. Twelve geophones where positioned in a dense

grid around the blasting area in order to monitor the

blast vibrations in the most efficient way.

The results showed that the measured vibrations are

very irregular and further tests will be needed to derive

proper prediction formulas. It is further planned in a

bigger project to investigate this topic and to implement

vibration prediction procedures into the company's

management system where the data can be

systematically analysed for each blast and an isoline plan

can be developed for the different blast sites.

During the last year the Chair of Mining Engineering &

Mineral Economics worked together with the Institute of

Plastics Processing on the project cont-blast charging

unit. The project was assigned with the PRIZE-award for

developing prototypes by the Austrian Wirtschafts-

service GmbH.The aim of the project is the development of a prototype

for centered charges, applied in the contour of

underground drift blasts in combination with bulk

emulsion explosives. The advantages of the system are

that the more and more used bulk emulsion products in

underground blasting can now also be used for smooth

blasting in the contour holes. Until now smooth blasting

with decoupled charge is only done with cartridges or

detonating cord. Various filling tests in the laboratory as

well as in the field with emulsion matrix and emulsion

explosive were already done to proof the functionality of

the system. Blasting field tests in underground drifts are

planned in the near future to further develop and

improve the system. Several patents have already been

granted.

In the frame of a Master thesis the technical and

economical performance of the CopRod drilling system,

developed by Atlas Copco, was analyzed.The CopRod system is an innovative drilling system,

where a hydraulic tophammer generates the percussion

energy which is transferred to the drill bit by special

inner drill rods. The rotation of the drill bit is activated by

rotating outer drill tubes. With this technology the

CopRod system combines the advantages of a

tophammer system (high drilling rates, low fuel

consumption) with those of a down the hole (DTH)

hammer system (better drilling accuracy).

The aim of the Master thesis was to find out where the

Cop Rod drilling systems stands in comparison to

tophammer and DTH drilling machines when used for

drilling of blast holes in typical quarries in Central

Europe.For that purpose measurements on CopRod and DTH

rigs were carried out in Austria. The measurements

comprised the determination of the dri l l ing

performance, the fuel consumption and the drilling

accuracy. In addition for the various drilling systems

analyzed, the total drilling and blasting costs were

determined and compared.

Sustainable Aggregate Management

An important activity in the field of Sustainable Resource

Management and Sustainable Supply Policies is SARMa

(Sustainable Aggregates Resource Management). This

project, focused on construction materials is co-

financed by the European Commission under the

framework of the SEE program (South East Europe -

Transnational Cooperation Program).

This project started in May 2009, its duration is 30

months until October 2011 and has a total budget of

1.900.000€. In SARMa 23 partners from 10 European

Straight holes drilled with the CopRod-System

(AT, SI, GR, IT, HU, RO) and non EU countries (HR, SRB,

AL, B.i.H) integrate not only their competence and

expertise in resources and environmental issues,

policies and regulations affecting aggregates but also

will give emphasis to capacity building activities.

Aggregate resources are essential for infrastructure

and development. Construction is predicted to grow 4,2 % per year in new EU-members, post-recession,

requiring steady, efficiently produced and adequate

supply of aggregates. The discrepancy in aggregates

management practices and policies among old and new

EU member states and candidate countries is large.

Fulfilling demand requires an eco-efficient and

sustainable supply chain (planning, extraction,

transport, use and recycling) and socio-eco friendly

quarrying, to preclude opposition to extraction and

restricted growth.

The two main objectives of this project are to develop a

common approach to Sustainable Aggregates Resource

Management (SARM) across SEE and ensure

Sustainable Supply Mix (SSM) in SEE based on fair

distribution of costs and benefits of aggregate

production, use, waste disposal and recycling, so as to

enhance resource and energy efficiency and quality of

life.

SARMa is structured in 5 Working Packages (WP).

WP1: Project management; WP2: Communication and

dissemination; WP3: Extraction and demolition site

level; WP4: Regional and national level activities WP5:

South East Europe Transnational Level Activities.

Besides participating in the creation of a SARM method

and SSM policies, the Chair of Mining Engineering &

Mineral Economics as the leader of Work Package 5

(start in August 2010) wil l coordinate the

implementation of transnational view of the theoretical

and practical outputs and results of the mentioned fields of

activity in SEE.

Within this work package cross-border case studies

among (AT-SI-HU-HR and in GR, RO, IT) will take place andwill lead to the recommendations for harmonization and

creation of a multi-purpose, multi-scale interoperable AIS

(Aggregates Intelligence System) for SEE.

Recommendations on the transnational level for

decision-makers on Sustainable Aggregates Resource

Management; a manual on SARM and SSM (Sustainable

Supply Mix) at regional, national and transnational

levels; and a feasibility study for the Regional Centre on

SARM and SSM will be the main outputs of Work

Package 5.

Observed studies indicate that the need for aggregates

increases steadily and the access to proper deposits

therefore has to be secured. Several projects at the

Chair of Mining Engineering & Mineral Economics take

this issue into account. The ANTAG project was first

developed and applied in France to deliver national and

regional authorities a detailed forecast on many critical

issues regarding aggregates. Based on the results the

French stakeholders are able to undertake measures to

ensure a sustainable supply of aggregates in the future.

The project itself splits up into certain sub-models (e.g.

consumption, transport, environment, etc.) which can

be combined to a single integrated model. This powerful

tool has been successfully introduced in France. Since

2007 the development of the ANTAG project in Austria

is handled by the Chair of Mining Engineering & Mineral

Economics at the University of Leoben in cooperation

with Ècole des Mines de Paris. There have been several

spot-checks in certain regions of Austria which were

discussed in a bachelor thesis. The bachelor thesis

included a feasibility study and proper frameworks for

applying the ANTAG project in Austria and provided the

fundamental basis for the ongoing work on the project.

In 2009 the Chair of Mining Engineering started to work

out adequate models for illustrating the consumption of

aggregates in Lower Austria and Vienna. The project

lasts till October 2010 and the results are estimated to

have an impact on the Austrian Mineral Resources Plan.

So far the sub-model “Consumption” has been designed

and calibrated with mathematical equation systems.

With the support of e.g. the Lower Austrian Economic

Chamber the research for proper data is way more

comfortable than expected.

Monitoring of buildings under water (like pillars of

bridges) are today still performed by divers. This

monitoring with divers is very dangerous and expensive.

Main problems are here a high rate of flow and the

reduced visibility in turbid water. To protect the divers

very large stealing-cages are used and the flowing water

must often be reroutet. With new measuring methods

using a high frequency sonar save and efficient

monitoring is possible under save conditions to detect

fractures in the pillars of the bridge. Customer: Brandner Wasserbau, Wallsee an der

BlastMetrix3D is a system for surveying bench faces

and for planning and controlling of blast patterns using

metric three dimensional digital pictures. It was

developed especially for use in small and medium sized

quarries and is based on 3D picture capturing system.

The program was designed in a cooperation of 3G

software and measurement, the Chair of Mining

Engineering (University of Leoben) and Mineral/

Strabag SE.The aim of the current research work on BlastMetrix is

to design and built a full scale calibration site in the scale

of the real survey applications. This should contribute to

an improved system stability and higher accuracy.

In the context of the cooperation between the DCM

DECOmetal and the Chair of Mining Engineering &

Mineral Economics a MSc thesis was prepared to

sustainably optimize and develop the underground

chromite mine in Bulqiza, Albania. The target of the work

was to examine the actual situation of ore transport

from stope to surface in order to create a basis for

future improvements in terms of safety and productivity.

Based on several weeks on site work a documentation of

bottlenecks, capacities and procedures along the

transport chain was prepared and possible

measurements for improvement were elaborated. In

addition the change to a new alternative transportation

system in the form of a roof-mounted monorail train for

the deeper levels of the mine was planned and

evaluated.

In 2008 420.000,00 Euro – of which 55% were funded

by EFRE and the federal state of Styria - were invested in

new measuring systems and an upgrading of existing

lab-infrastructure. All in all the Chair of Mining

Engineering & Mineral Economics purchased 18

individual systems, of which the core drilling machine

DE110 of SANDVIK (holes up to 100 m) can be

considered as the investment highlight. Besides the

core drilling machine the following equipments were
