This U.S. Bureau of Mines paper focuses on the noise exposure levels of miners employed on longwall production faces. Along with the increased production from longwall units has come the potential for greater noise exposures. Typical noise levels are given for the various noise sources that are present on modern longwall faces. Exposure times have typically increased since the introduction of longwall technology in this country. Representative exposure times and patterns are analyzed. Possible solutions are presented for generalized cases. Engineering controls developed by the Bureau are explained and their potential effectiveness is calculated for the cases presented. The role of hearing protectors in an overall hearing conservation program is also investigated. Recent Bureau research suggests that the actual performance levels of muff-type protectors may be less than the manufacturers' ratings under certain circumstances. The use of muff-type protectors is discussed and analyzed with respect to longwall operations.
