This report summarizes the Bureau of Mines noise-control research program from 1972 to 1982. Each segment of the mining industry-- underground coal, underground hardrock, surface mining, and processing plants--has different noise-control problems because of vast differences in working procedures, equipment, and workplace design. The Bureau has identified the most serious noise problems in each segment and has developed strategies for attacking these problems. This publication points out the need for noise control in the mining industry, discusses federal regulations governing worker exposure to noise, and describes the Bureau's overall approach to mining noise-control research. It traces the history of noise overexposure in each segment of the mining industry and discusses the major noise sources. It provides detailed information on noise- control research efforts in the Bureau's major areas of emphasis, including the results of these efforts. Finally, the report discusses the Bureau's future role in research on mining noise control, emphasizing the need to expend more effort on long-term in- house investigations into the noise problems that have been identified in past programs as the most serious ones.
