New cutting concepts for continuous miners.
Coal Min Process 1979 Oct; 16(10):62-67
A new coal cutting concept is being developed by the Bureau of Mines for underground mining. The mining resulted from recent research on the effects of cutting parameters on the generation of airborne respirable dust. The specific dust decreased substantially with increasing depth of cut. This led to the concept of a constant depth linear cutting head that would reduce the amount of dust generated by the coal cutting process. The constant depth linear cutting head, which can be retrofit to current mining machines, would also increase bit life, and reduce both noise and methane ignition potential.
