This Bureau of Mines paper describes a new highwall mining system (hms) for coal extraction in unreclaimed and active contour strip mines. This prototype system is comprised of a computer-based remote control system to monitor and remotely control a thin-seam continuous miner (tscm) and a 76-m-long multiple-unit continuous haulage (much) conveying system, plus other manually operated support equipment located on the highwall bench. The tscm and much coal haulage system are both controlled remotely by a single operator in a protective enclosure at an ergonomically designed workstation located on the highwall bench. Two other personnel work on the bench to operate other support equipment. Full-scale mockup fabrications were employed in the design of the unique remote control operator workstation. The hms should allow the safe and economical exploitation of increased coal reserves where they outcrop in hilly regions of the United States. It should also be competitive with conventional auger mining and other coal extraction techniques, with a productivity goal at a highwall site of 20 mt/man- h.
