Mine Explosions - an overview | ScienceDirect Topics
2018-3-17 · Proper coal mine degasification minimizes, if not eliminates, the danger of mine explosion and the loss of lives. It also cuts down the cost of coal production. These two advantages alone justify degasification of all moderately and highly gassy coal seams. Moreover, the recovered gases can be gathered, processed, and sold for added revenues.
