  4/18/2013 - Training materials, Videos and multimedia
  This is a series of 5 videos explaining how to use the coal dust explosibility meter.
• NIOSH Hazard ID 16 - Non-Conforming Rock Dust
  10/1/2011 - Hazards IDs
  In September 2011, as part of an ongoing investigation, NIOSH determined that rock dust not conforming to the requirements in 30 CFR Part 75.2 for particle size and caking properties is being used in U.S. underground coal mines.
• Methane-Air Detonation Experiments at NIOSH Lake Lynn Laboratory
  9/1/2010 - Conference papers
  This paper describes the first phase of research aimed at understanding explosion pressures that can develop in coal mines and the factors that lead to high explosion pressure and possible transition to detonation.
• Rock Dusting Considerations in Underground Coal Mines
  6/1/2010 - Conference papers
  This paper discusses factors that could result in a potential undetected dust explosion hazard, when using current dust sampling procedures, in an area that otherwise appears to be adequately protected with rock dust.
• Reducing the Fire and Explosion Hazards of Flame-Cutting and Welding in Underground Coal Mines
  6/1/2010 - Peer reviewed journal articles
  This paper provides a summary of work done in a study on fires and explosions in underground U.S. coal mines that were caused by flame cutting and welding operations to determine the root causes of these types of fires and explosions.
• Recommendations for a New Rock Dusting Standard to Prevent Coal Dust Explosions in Intake Airways
  5/1/2010 - Reports of Investigations
  This NIOSH report presents the results of extensive in-mine coal dust particle size surveys of dust samples collected from intake airways in 61 U.S. coal mines, representing all 10 MSHA bituminous Coal Mine Safety and Health Districts.
• A Centennial of Mine Explosion Prevention Research
  2/1/2010 - Conference papers
  This paper provides a brief historical overview of full-scale mine explosion research conducted primarily at the USBM, now the National Institute for Occupational Safety and Health (NIOSH).
• Mitigating Coal Dust Explosions in Modern Underground Coal Mines
  11/1/2009 - Conference papers
  NIOSH has investigated several areas in which current practices may need to be updated to adequately protect mines against coal dust propagated explosions. Other closely related issues, such as rock dust testing methods, are also discussed.
• Compendium of Structural Testing Data for 20-psi Coal Mine Seals
  8/1/2009 - Information Circulars
  This report presents nearly all structural data available from explosion tests of 20-psi mine ventilation seals and concrete-block ventilation stoppings that were conducted by the NIOSH during 1997-2008.
• Technology News 535 - NIOSH Releases New Educational Video: Escape from Farmington No. 9: An Oral History
  5/1/2009 - Technology News
