• 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.
• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• Evaluating Portable Infrared Spectrometers for Measuring the Silica Content of Coal Dust
  1/1/2012 - Peer reviewed journal articles
  Miners face a variety of respiratory hazards while on the job, including exposure to silica dust which can lead to silicosis, a potentially fatal lung disease.
• Benchmarking Longwall Dust Control Technology and Practices
  9/1/2011 - Peer reviewed journal articles
  Results from the NIOSH underground dust surveys and current longwall dust control technology and operating practices are discussed.
• 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.
• 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).
• Continuous Miner Spray Considerations for Optimizing Scrubber Performance in Exhaust Ventilation Systems
  2/1/2010 - Conference papers
  This paper describes lab experiments to examine the effect of spray type, pressure, machine body blocking sprays, and scrubber airflow on dust and gas levels while using a 12.2 m (40 ft) exhaust ventilation curtain setback from the face.
• 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.
