The design of underground mining machinery has generally stressed the technical and engineering aspects related to the machine's functions over the needs of its human operators. This has resulted in machines that strain the capabilities of their operators and contribute to the high accident rate during the operation of mobile underground coal equipment. In 1984, there were 1,822 injuries to miners while operating or riding in underground mobile equipment. This amounts to 17 pct of all injuries that occurred in underground coal mining during that year. A study conducted by the Mine Safety and Health Administration found that 36 pct of the fatalities involving underground coal mobile equipment were related to improperly designed operator compartments. Operators must often lean outside the confines of the compartment in order to steer the equipment, increasing the likelihood of striking the rib or roof. Controls are often unlabelled and placed where they are difficult to reach and cannot be distinguished from one another. In panic situations, the wrong control may be activated, which can lead to accidents. To address these and other related problems, the U.S. Bureau of Mines is developing a computer-based model to aid in the analysis of the human engineering aspects of mining equipment design. The model, known as cap (crewstation analysis programs), is intended for use by original equipment manufacturers and mining companies for the initial design work on new machines, and to evaluate proposed modifications to existing machines. This article outlines the overall stru
