Training Miners to Recognize Roof and Rib Hazards Using 3-D Slides.

Barrett-EA; Wiehagen-WJ
Proc Tram XIV 1987 :122-130
Ground control accident reports frequently have concluded that injuries and fatalities occurred because roof or rib hazards were not detected by the worker. One component, therefore, in the prevention of such accidents could be the ability of miners to recognize the visual cues that are associated with the geologic or mining-induced irregularities that precede roof and rib falls. Even though knowledge of hazardous ground conditions may be extensive due to years of experience, the miner may not be competent in recognizing the warning signs of imminent danger. The competent miner, as a minimum, should be able to perceive, recognize, and correct potentially dangerous roof and rib conditions. The visual skills needed for recognition of ground hazards may be taught in the classroom if training aids are available that can realistically simulate actual mine conditions. Stereoscopic (3-d) slides are that type of training aid, a high-fidelity medium for representing roof and rib hazards, and, as such, provide an excellent proxy for instructing miners about dangerous ground conditions. To this end, practical and inexpensive 3-d photographic equipment and procedures have been advanced by the Bureau of Mines to the level that mine companies can develop, in-house, customized, stereo slide ground control training materials.
