This U.S. Bureau of Mines study describes the positioning strategies used by operators of radio-controlled underground mining machines. The observations have implications for task design to ensure adequate visibility and task performance. Radio-controlled continuous coal mining machines have allowed many mines to increase safety and production by placing human operators away from the hazards of an unsupported mine roof. The operator is no longer confined to an operator's compartment, and visibility can be enhanced with proper positioning. Also, the operator is no longer subjected to the shocks and vibrations of the mining machine. The operator's ability to move freely about the worksite requires a careful analysis of several competing safety and production considerations. Thirty-five operators of remotely controlled continuous mining machines were observed using work sampling followed by interviews to determine where the operator was positioned and what he or she was watching. Portions of the mining task place visibility demands on the operators that are difficult to accommodate within existing procedures. The operator's vision can be augmented through video cameras in future teleoperated mining systems, and the operator can be increasingly isolated from environmental hazards.
