• A Review of Recent Accidents Involving Explosives Transport
  3/1/2009 - Peer reviewed journal articles
  This article is a review of recent accidents involving explosives transport both in the United States and outside of the United States.
• 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.
• Methods for Controlling Explosion Risk at Coal Mine Working Faces
  9/1/2007 - Conference papers
  This paper reviews how simultaneous application of three basic elements reduces the methane explosion hazard at coal mine working faces: (1) adequate ventilation, (2) regular monitoring of gas concentrations, and (3) elimination of ignition sources.
• Explosion Pressure Design Criteria for New Seals in U.S. Coal Mines
  7/1/2007 - Guides and manuals, Information Circulars
  This report provides a sound scientific and engineering justification to recommend a three-tiered explosion pressure design criterion for new seals. The recommendations contained herein apply to new seal design and construction in U.S. coal mines.
• Threshold Powers and Delays for Igniting Propane and Butane-Air Mixtures by CW Laser-heated Small Particles
  11/1/2006 - Peer reviewed journal articles
  NIOSH researchers studied laser safety in potentially flammable environments. Researchers measured threshold igniting powers as a function of beam diameter for butane and propane-air mixtures by laser-heating targets placed on optical fiber tips.
• Methane-Air Mixtures Ignited by CW Laser-Heated Targets on Optical Fiber Tips: Comparison of Targets, Optical Fibers, and Ignition Delays
  9/1/2006 - Peer reviewed journal articles
  Researchers conducted experiments to estimate the mean and standard deviation of laser powers needed to ignite 6% methane-air atmospheres using single-mode optical fiber tips covered by two types of iron oxide mixed with a ceramic adhesive.
• 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.
• Analysis of Mine Fires for All U.S. Underground and Surface Coal Mining Categories: 1990-1999
  9/1/2004 - Information Circulars
  This report analyzes mine fires for all U.S. underground and surface coal mining categories by state and 2-year time periods during 1990-1999.
• Continuous Wave Laser Ignition Thresholds of Coal Dust Clouds
  8/1/2003 - Peer reviewed journal articles
  Laser-based instruments are used in areas where coal dust ignition presents a safety hazard. This NIOSH study determines when an optical beam may be considered a potential ignition source in underground coal mines or coal storage facilities.
