Rock Mechanics Studies During Continuous Miner Bases Coal Pillar Extraction in Indian Coalfields

Original language description

Indian coal mining industry has introduced a number of fully mechanized depillaring operations/faces at depth of cover ranging from 60 m to 377 m. Nature of overlying strata of these depillaring faces varied widely; from highly laminated, weak and easilycaveable to massive, strong and difficult to cave. These mechanized depillaring operations are, generally, carried out at difficult site conditions but performance monitoring in field showed good production, productivity and safety results. Applicationof roof bolts as breaker line support for this technology worked well for moderate overlying roof strata but experienced difficulties for, both, extremely weak and strong/massive overlying roof strata. It is observed that the performance of a breaker line support at the goaf edge deteriorated with an increase in depth of cover of the depillaring face. Practice of a straight line of extraction (single row of pillars) during the mechanized depillaring below competent roof strata experience
