• Investigation of Coal Properties and Airborne Respirable Dust Generation
  10/1/1998 - Reports of Investigations
  Laboratory testing and results are presented where five bituminous coals were prepared and processed through a double roll crusher located in a low-velocity wind tunnel. The results indicate that a combination of several factors are associated with air...
• Technology News 463 - Machine-Mounted Continuous Respirable Dust Monitor
  7/1/1997 - Technology News
  A machine-mounted continuous respirable dust monitor is discussed that can accurately monitor, display, and record concentration levels of respirable coal mine dust in mines for extended periods.
• Bag and Belt Cleaner Reduces Employee Dust Exposure
  3/1/1997 - Peer reviewed journal articles
  A system to reduce occupational dust exposure during bag loading and stacking operations in the metal mining industry was developed. The system, known as the Bag and Belt Cleaner Device (B&BCD), was developed by NIOSH.
• Status of Dust Control Technology on U.S. Longwalls
  2/1/1997 - Conference papers
  NIOSH conducted dust surveys at 13 longwalls operating throughout the U.S. and collected information to: identify current operating practices on these longwalls, identify the types of dust controls in use, etc.
• Continuous Respirable Mine Dust Monitor Development
  2/1/1997 - Conference papers
  NIOSH initiated the development of a fixed-site machine-mounted continuous respirable dust monitor. The technology chosen for monitor development is the Rupprecht and Patashnick Co., Inc. tapered element oscillating microbalance. Laboratory and in-mine ...
• Continuous Respirable Mine Dust Monitor Development
  8/1/1996 - Conference papers
  In response to an MSHA task group recommendation, the National Institute for Occupational Safety and Health (NIOSH), Pittsburgh Research Center, initiated the development of a fixed-site machine-mounted continuous respirable dust monitor.
• Criteria for a Recommended Standard: Occupational Exposure to Respirable Coal Mine Dust: Occupational Exposure to Respirable Coal Mine Dust
  9/1/1995 - NIOSH/USBM numbered publications
  Information regarding adverse health effects resulting from exposure to respirable coal mine dust was reviewed as a basis for the development of new occupational safety and health standards. Recommendations are provided concerning respirable coal mine d...
• 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.
• 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.
