• Description:
  The Bureau of Mines has recently completed a program to identify and evaluate various methods that address control of dust generated outby the longwall mining face. Dust generated by the stageloader- crusher, the panel belt, and the intake roadway can be long-term throughout the shift, contributing significantly to the dust exposure of all face workers. Dust control techniques were identified and tested at a number of longwall mining sections located in diverse geological conditions across the United States. Dust controls investigated include (1) methods that eliminate the sources of intake dust contamination--homotropal ventilation, (2) methods to limit the amount of respirable dust released into the intake airstream--improved water application and the use of curtains and enclosures, and (3) methods to clean the contaminated air prior to delivery to the mining face--scrubber systems. Usually they can be implemented at a low cost and can be very effective. This report describes each technique and its application and presents the resulting conclusions.
