• How to use the Coal Dust Explosibility Meter
  4/18/2013 - Training materials, Videos and multimedia
  This is a series of 5 videos explaining how to use the coal dust explosibility meter.
• Coal Dust Explosibility Meter Evaluation and Recommendations for Application
  8/15/2012 - Information Circulars
  This IC details a NIOSH investigation on the CDEM’s ability to accurately predict the explosibility of coal and rock dust mixtures. The conclusions support the field use of the CDEM to measure the explosibility of coal and rock dust mixtures.
• 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.
• 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.
• 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.
• 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.
• Field Evaluation of the Coal Dust Explosibility Meter
  10/1/2008 - Peer reviewed journal articles
  This paper describes the testing and reliability of results of a NIOSH developed Coal Dust Explosibility Meter (CDEM), a hand-held instrument that uses optical reflectance to measure the explosibility of a rock dust and coal dust mixture.
• Coal Dust Particle Size Survey of U.S. Mines
  8/1/2006 - Conference papers
  NIOSH and MSHA conducted a joint survey to determine the range of coal particle sizes found in dust samples collected from intake airways of U.S. coal mines.
• Technology News 515 - Float Coal Dust Explosion Hazards
  4/1/2006 - Technology News
  This publication is intended to promote awareness of float coal dust explosion hazards in the mining industry and offers a float coal dust mitigation technique.
• Coal Dust Explosibility
  1/1/1996 - Peer reviewed journal articles
  This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal.
