Constant-depth Linear Cutting Head for Continuous Mining Machines. Engineering and Economic Feasibility Study.
NTIS: PB 267 927 Available for Reference At Bureau Libraries :194 pages
This report describes the engineering feasibility and economic advantage of a unique new mining machine using cutting bits that take a constant-depth linear cut in the coal face. The studies show that this innovative new cutting concept, being developed by the Bureau of Mines, can be designed into the basic continuous-mining machine. The resulting miner would be attractive to mine owners because coal could be mined with minimum generation of airborne respirable dust, substantial increases in productivity, and elimination of methane ignition due to cutting.
