Abstract

In India over 2500 million tons of coal is locked in thick seams beyond open cast limit due to important features like township, river and rails etc (Singh & Dubey, 1993). The conventional bord and pillar method of mining with splitting and stoking has never exceed 35% production under such constraint. The basic concept of wide stall method of mining is widening of the galleries in two sections and reducing the parting thickness in between to maximize the coal recovery upto 50 to 55% with stable pillar and without any surface damage. Results obtained for a particular case of mine indicated that the pillar formed during wide stall mining is much safer than the conventional method of splitting and heightening. It showed a good scope to improve the production and productivity upto 52% recovery level without making pillar failure.
