Development of Highwall Mining Equipment (Phase I). Volume I.
NTIS: PB 297-828 :109 pages
This report describes the work done to develop a coal mining machine to increase productivity and recovery from thin seams beyond the highwall and to decrease the miner's susceptibility to highwall hazards. First, radar transducers were adapted to measure coal thickness and detect rock and coal interfaces, then the radar was incorporated into a cutterhead with steering controls. Next, visual displays were designed to show cutter position in the coal seam and anticipated change in coal seam inclination. Finally, development of a telemetry system made remote control of the cutterhead possible. Volume I provides an overview of the machine, systems, and productivity.
