Hard-wired or radio remote control of continuous mining machines has been available since the early 1970's. This type of remote control situates the machine operator offboard, but within direct view of the underground coal face. The operator is positioned under permanent roof support but is still exposed to the hazards of roof and rib falls, dust, and methane explosions. Since 1979, the U.S. Bureau of Mines has researched alternative methods to remove the machine operator from these hazards. Working with a private cooperator since 1985, the Bureau has developed an offboard, computer-based remote control system that stations the operator hundreds of feet distant from the working face in a highwall mining operation. Details of this new remote control or "teleoperated" highwall mining system (continuous miner + continuous haulage) at a West Virginia field trial site are described, along with plans to incorporate this technology for thin-seam extraction and haulage equipment in deep, room-and-pillar coal mines.
