Health requirements for advanced coal extraction systems.
Washington, DC: U.S. Department of the Interior, Bureau of Mines, Contract C-12548, 1980 Sep; :1-28
Health requirements have been developed as long-range goals for future advanced coal extraction systems which would be introduced into the market in the year 2000. The goal is that underground coal miners work in an environment that is as close as possible to the working conditions of the general population. The primary health requirements for advanced coal extraction systems are that coal dust be reduced to less than 2 mg/m/sup 3/, and that carcinogens and mutagens be reduced to levels typical of the air in large urban centers. Secondary requirements are that: (1) relative humidity be between 50 and 75% and that temperature be between 65 and 78/sup 0/F, with no extreme swings in either; (2) noise and lighting levels conform to present MSHA standards; (3) working space accommodate most body configurations, and (4) vibration damping equipment be provided. A brief technique for evaluating whether proposed advanced systems meet these safety requirements is presented, as well as a discussion of the costs of respiratory disability compensation. Appendices describe the effects of coal dust ingestion, suggest a recommended technique for detecting potential carcinogens, and present tables of accepted working space standards.
