Reduced standards resulting from exposure to coal mine dust containing more than 5% quartz are currently one of the most serious health compliance problems facing both the underground and the surface coal mining industry. In 1982, the Bureau of Mines initiated research to identify sources of quartz dust and means to allow mine operators to comply with more stringent standards. Results to date have identified the sources of quartz dust for both underground and surface operations from both a geological and an operational viewpoint. Control techniques involving improved dust scrubber systems, high-pressure sprays, improved spray systems, mining cycle modifications, and better roof bolter maintenance have been identified and evaluated. The Bureau is continuing in-house and contract research designed to allow mine operators to comply with the more stringent standards established to protect the health of the coal mining work force, without adversely affecting productivity.
