INTERNATIONAL CENTRE FOR EXCELLENCE
IN MINING
[Session: Technology, Safety & Research]
Ahmedabad: 21st May 2013
LIGNITE MINING IN GUJARAT:
Gujarat has over 2700 million Tonnes of Lignite Reserves:
- Only about 40 % (i.e. 1000 mT) Mineable by Surface Mining
- Rest 60 % (1700 mT) needs technologies like UCG.
UCG is not tried even on Pilot scale in India. Technology needs to be
developed to exploit these lignite reserves.
Pit & Dump Slope Stability: Threat to Lignite Mining
Increasing depth of opencast mines necessitates more research to
find out better strata control technologies
Designing of safe & stable slopes,
Working out Safe Working parameters (limiting depths, etc.),
Effective Prediction, Detection & affordable Warning Systems.
COAL & LIGNITE MINING IN INDIA:
Large quantity of Coal / Lignite Reserves are locked in batter:
Development & Undertaking of Highwall Mining Projects.
Lignite has high sulphur / pyrite contents:
Technologies for Desulphurization and separation of Pyrite Nodules.
Excavation of Hard Strata / Alternatives to Blasting.
Long Distance Transportation: not very cost effective.
- Liquefaction & Transportation in liquid form,
- Surface gasification & Transportation of Gases.
Mining of deep Seated Coal Deposits:
Coal to Liquid Technology.
MINERAL BENEFICIATION AND VALUE ADDITION PROJECTS:
Exploitation of Small but qualitatively rich deposits:
[like Ambaji Base Metal deposit]
Value Addition of Silica Sand.
Recovery of Low grade mineral from old dumps of mineral
rejects.
Utilization of tailings & Mineral wastes.
Development of Mining Methods for recovery of Marble from
greater depths.
Development of Technologies which can allow mining within
eco-sensitive zones.
MINING MACHINERY:
Technological Development in Heavy Earth Moving Machinery
and Underground Mining Machinery:
- Better Fuel efficiency,
- Eco-friendly,
- Cost effective higher capacity machinery, and
- Technologies which can provide better availability.
APPLICATION of IT in MINING:
Use of Cost-effective Software in Mine Planning & Designing.
Sophistication in Mine Surveying Equipment,
Mineral Exploration and modeling,
Cost-effective Vehicle Tracking Systems,
Computerization for Machinery Performance Data,
Use of satellite imageries.
