Significant improvements in production from longwall and continuous mining operations have occurred in the underground coal mining industry in the United States (U.S.) over the past fifteen years. For longwall operations, increases in panel size and equipment power, improved equipment reliability, and improved operating practices have contributed to a four-fold increase in average shift production. Similar improvements in continuous miner capabilities and the utilization of extended-cut mining procedures have allowed production from continuous mining sections to approximately double over this time period. Unfortunately, as more coal is mined, greater quantities of respirable dust can be generated and the potential for worker overexposure to harmful levels of coal dust increases. In addition, as rock partings in the coal seam or rock surrounding the coal is cut, the generation of respirable silica dust becomes a health concern for miners. A substantial number of continuous miner sections continue to experience difficulty with controlling silica dust generation. The Pittsburgh Research Laboratory of the National Institute for Occupational Safety and Health (NIOSH) is responsible for conducting respirable dust control research for the U.S. coal mining industry .An overview of current dust control practices for longwall and continuous mining operations in the U.S. will be presented. Information regarding face ventilation practices and water spray application for longwalls, ventilation and dust control practices for extended-cut continuous miner operations, silica dust collection for flooded-bed scrubber dust collectors, and a summary of ongoing NIOSH dust control research for underground coal mining will be provided.
