- Abstract
- This report covers a one-year industrial engineering study of working face hazards in underground bituminous coal mines. The field data were accumulated from observations in 50 underground mines in all parts of the United States. Supporting data for the analysis was derived primarily from Bureau of ZMines fatal accident reports from 1966 through 1970. A strong relationship was found to exist between fatal accident occurrences and low task experience. This led to a recommendation for formalized training, certification, and supervision programs for miners. Analysis of roof fall variables revealed a fatal propensity on the part of the miners to work under unsupported roof or under support conditions that are marginal. The report also covers 12 fatality reduction projects that focus on highly hazardous areas identified through the fatal accident report analyses and undergroundindustrial engineering observations. Recommendations are evaluated in terms of estimated annual cost to the industry and estimated potential lvies saved. The report discusses temporary and permanent support installations, maintenance and repari accidents, operator protection on face equipment, shuttle haulage, machine loading, roof fall accidents, and auger-type continuous mining accidents.
