Developments Made for Mechanised Extraction of Locked-Up Coal Pillars in Indian Geomining Conditions
Bord and Pillar method of underground mining has been used extensively to develop Indian coal seams into pillars and galleries. This results in only 20–30% recovery of coal and rest coal remain locked up in developed pillars. Indian coalfields are famous in the world for its uniqueness and complexit...
