Computer-based, teleoperation of a new highwall mining system

A technology has been developed to economically mine a greater percentage of coal reserves in highwall outcrop settings. This mining system features a computer-based teleoperating subsystem for distant, non-line-of-sight control of a thin-seam continuous miner and coal haulage units. A single operator, situated at an ergonomically designed workstation within a protective enclosure on a highwall bench, controls all the coal extraction and haulage equipment that penetrate the coal seam deep within the hillside. The workstation consists of a special chair, two control modules, two color video monitors, an array of displays, and a control computer. Details of this operator workstation, a summary of the overall highwall mining system, and current test status are discussed.<
