Continuous Miner Operators Situate Themselves for Safety and Better Visibility.
Coal 1992 Apr; :63-64
Many mines have significantly increased safety and production by placing miner operators away from the hazards of unsupported roof using radio-remote-controlled continuous miners. Most mines have a standard operating procedure (sop) outlining continuous miner operator positioning. Sometimes the situation requires the operator to vary from sop. Such situations pose positioning questions to management. The U.S. Bureau of Mines has been conducting research on radio-remote-controlled miner operator positioning. The research has primarily examined the relationship between sop and actual positioning. Differences between the two help determine information that the operator needs when performing certain tasks.
