• Reducing Respirable Dust Concentrations at Mineral Processing Facilities Using Total Mill Ventilation Systems
  1/1/1993 - Reports of Investigations
  The design and evaluation of two total mill ventilation systems are described. Both systems proved to be very effective at reducing respirable dust levels in a cost-effective manner, were easy to install, and required minimal maintenance.
• Water Infusion - An Effective and Economical Longwall Dust Control
  1/1/1983 - Reports of Investigations
  In Europe, water infusion is used widely to reduce generation of respirable dust during mining. Its use in the United States is limited to a few plow operations in the Pocahontas No. 3 Coalbed. This Bureau of Mines report describes the technology for in...
• 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...
• Methane and Dust Controls for Longwalls: Pocahontas No. 3 Coalbed, Grundy, Va.
  1/1/1974 - Reports of Investigations
  The periphery of longwall panels in the Pocahontas No. 3 Coalbed is characterized by a zone of reduced permeability that inhibits the natural drainage of methane. However, natural drainage holes drilled during development have been found to reduce the g...
• Methane and Dust Control by Water Infusion: Pittsburgh Coalbed (Fairview, W. Va.)
  1/1/1972 - Reports of Investigations
  The effect of water infusion on the flow of methane and on the production of dust was investigated at an active face in the Pittsburgh coalbed. The average total flow of methane at the face decreased by approximately 79 percent, whereas the flow from th...
• Dust Control Handbook for Industrial Minerals Mining and Processing
  1/1/2012 - Guides and manuals, Reports of Investigations
  Mined ore undergoes crushing, grinding, cleaning, drying, and product sizing as it is processed, generating harmful dust. This handbook reviews technologies for lowering dust levels below the permissible or recommended occupational exposure limits.
• Best Practices for Dust Control in Metal/Nonmetal Mining
  5/1/2010 - Information Circulars, Safety guidelines, tips, and checklists
  This handbook was developed to identify available engineering controls that can assist underground and surface metal/nonmetal mining operations in reducing worker exposure to respirable silica dust.
• Best Practices for Dust Control in Coal Mining
  1/1/2010 - Information Circulars, Safety guidelines, tips, and checklists
  This handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust.
