Survey of respirable dust control research in underground coal mines 1979.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, 1980 May; :1-145
A survey of 80 coal producers was conducted to determine the extent and scope of respirable dust control research for underground coal mines and the current methods employed to control respirable dust. Results of the survey showed that proper face ventilation and an adequate water spray system are sufficient to comply with mandatory standards in room-and-pillar mining. Difficulties still exist with longwall equipment, auger miners, and boring machines. In these cases, known dust control techniques are not sufficient to obtain compliance. Present state-of-the-art face ventilation and water systems are discussed in addition to the sampling program.
