• Dust Considerations When Using Belt Entry Air to Ventilate Work Areas
  1/1/1992 - Reports of Investigations
  Dust surveys were conducted to determine factors affecting belt entry dust levels and how using belt air to ventilate work areas affected dust exposures.
• Relationship of Coal Seam Parameters and Airborne Respirable Dust at Longwalls
  1/1/1992 - Reports of Investigations
  The U.S. Bureau of Mines investigated the relationship of bituminous coal seam parameters and the amount of respirable dust generated at longwalls.
• Rapid Sampling of Products During Coal Mine Explosions
  2/1/1991 - Peer reviewed journal articles
  This paper describes a U.S. Bureau of Mines investigation of large-scale coal dust explosions in an experimental mine using a high-speed electropneumatic mechanism for rapid grab-sampling of gases and dusts and shows the benefits of the technique.
• Impact of Background Sources on Dust Exposure of Bag Machine Operator
  1/1/1986 - Information Circulars
  The Bureau of Mines has recorded a number of different background dust sources that significantly contaminate the air breathed by bag machine operators. To keep bag operator exposure within acceptable dust levels established by the Mine Safety and Healt...
• Water Infusion of Coalbeds for Methane and Dust Control
  1/1/1977 - Reports of Investigations
  This Bureau of Mines report deals with water infusion of coalbeds, which can control methane emission at face areas during developmental mining and which may sometimes suppress dust. Studies show that water infused into the coalbed flows through the fra...
