Roof support at the face (the area where coal is actively mined) is intended to hold the immediate roof above the coal face. In modern mechanized mines, roof bolting is the most common method employed. Steel bolts, usually to 2 metres long and 15 to 25 millimetres in diameter, are inserted in holes drilled into the roof by an electric rotary drill and are secured by either friction or resin.

The continuous miner technology (CMT) is being adopted extensively in underground coal mines of India as mass production technology. This technology potentially eliminates the twounit operating, namely the drilling and blasting. This elimination helps for better strata control and avoids the drillers working in unsafe conditions, maybe under the loose coal roof. This CMT improves the quality ...
