Abstract
Many longwall operations use dust helmets to reduce the respirable dust exposures of miners required to work downwind of crusher, roof support, and shearer operations. While continuous mining sections are usually less dusty, use of diesel equipment may represent a new potential health problem. Diesel particulates consist primarily of insoluble carbonaceous agglomerates and soluble organic compounds with some small concentrations of sulfates and trace metals. Some of the soluble organic compounds that are present in diesel soot have been shown to be carcinogenic in laboratory animals. To address these concerns, the U.S. Bureau of Mines recently conducted a study to determine the efficiency of a dust helmet on diesel particulates.
