WORKSHOP ON 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.
