Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine roof.
longwall mining was limited by the type of coal to be cut. With , this is no longer the case. Advancements in drive, control and transmission systems – with more powerful motors, stronger plow chains, increased plow speeds, higher advancing force provided by the roof supports, precise control of the cutting depth, and plow
Under the MINER Act of 2006, the Office of Mine Safety and Health Research (OMSHR) was charged with developing and adapting new mine safety technology and expediting its commercial availability through a contracts and grants program. With consideration for market drivers and barriers, current state-of-the-art technologies in mining versus other sectors, regulations that may potentially impact ...
