• Are lithium-ion cells intrinsically safe?
  11/1/2013 - Conference papers
  A NIOSH study investigating the potential for lithium-ion battery thermal runaway from an internal short circuit in equipment approved as permissible for use in underground coal mines.
• Technology for Real-Time Monitoring of Coal Dust Explosion Hazards
  10/1/2012 - News articles
  The NIOSH Coal Dust Explosibility Meter (CDEM) is available for purchase and use in underground coal mines. A recent Information Circular supports its use for real-time explosibility testing of rock and coal dust samples.

• Relationship Between Radiated Seismic Energy and Explosive Pressure for Controlled Methane and Coal Dust Explosions in an Underground Mine
  3/1/2012 - Peer reviewed journal articles
  This paper describes the research conducted to quantify a relationship between measured values of radiated seismic energy and peak explosive pressure generated.
• Evaluation of a Novel Fire Blocking Gel to Prevent and Suppress Mine Fires
  1/1/2012 - Peer reviewed journal articles
  This paper describes tests conducted to evaluate the effectiveness of the Barricade II Fire Blocking Gel.
• Factors Affecting Coal Particle Ignition Under Oxyfuel Combustion Atmospheres
  1/1/2011 - Peer reviewed journal articles
  Thirteen coals of different rank were tested for ignition propensity in a 20-L explosion chamber simulating oxyfuel combustion gas conditions. The effects of coal type, coal concentration, O2 in CO2 atmospheres, and particle size were investigated.
• Historical Development of Technologies for Controlling Methane in Underground Coal Mines
  1/1/2010 - Conference papers
  This paper discusses several milestone events that show the progress of methane control research in underground coal mines.
• Passive Mine Blast Attenuators Constructed of Rock Rubble for Protecting Ventilation Seals
  1/1/2010 - Peer reviewed journal articles
  This paper discusses some concepts and preliminary test results for a Passive Mine Blast Attenuator (PMBA) that can provide a useful alternative to increasingly larger and stronger stand-alone mine seals.
• How Does Limestone Rock Dust Prevent Coal Dust Explosions in Coal Mines?
  9/1/2009 - Peer reviewed journal articles
  This study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.
