This is a series of 5 videos explaining how to use the coal dust explosibility meter.
10/1/2011 - Hazards IDsIn 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.
9/1/2010 - Conference papersThis paper describes the first phase of research aimed at understanding explosion pressures that can develop in coal mines and the factors that lead to high explosion pressure and possible transition to detonation.
6/1/2010 - Conference papersThis 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.
6/1/2010 - Peer reviewed journal articlesThis paper provides a summary of work done in a study on fires and explosions in underground U.S. coal mines that were caused by flame cutting and welding operations to determine the root causes of these types of fires and explosions.
5/1/2010 - Reports of InvestigationsThis 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.
2/1/2010 - Conference papersThis 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).
11/1/2009 - Conference papersNIOSH 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.
Refuge Chamber Expectations Training was created by a multidisciplinary team at NIOSH to inform miners of what to expect psychologically and physically if it became necessary to use a refuge chamber in a mine emergency.
8/1/2009 - Information CircularsThis report presents nearly all structural data available from explosion tests of 20-psi mine ventilation seals and concrete-block ventilation stoppings that were conducted by the NIOSH during 1997-2008.
