• 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.
• 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.
• Equivalency of a Personal Dust Monitor to the Current United States Coal Mine Respirable Dust Sampler
  1/1/2008 - Peer reviewed journal articles
  The work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
• Laboratory and Field Performance of a Continuously Measuring Personal Respirable Dust Monitor
  9/1/2006 - Reports of Investigations
  This report includes the theory of operation, description, and the performance of the Personal Dust Monitor (PDM) compared to gravimetric-based reference dust sampling methods and laboratory verification of the instruments accuracy.
