Technology News 535 - NIOSH Releases New Educational Video: Escape from Farmington No. 9: An Oral History5/1/2009 - Technology NewsResearchers with NIOSH have developed a training module to educate both new, inexperienced miners as well as veterans on important issues related to self-rescue and escape procedures.
This video-based training module can be used to educate both inexperienced and veteran miners on important issues related to self-rescue and escape procedures.
3/1/2009 - Peer reviewed journal articlesThis article is a review of recent accidents involving explosives transport both in the United States and outside of the United States.
10/1/2008 - Peer reviewed journal articlesThis 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.
9/1/2007 - Conference papersThis 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.
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 Particles11/1/2006 - Peer reviewed journal articlesNIOSH 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 Delays9/1/2006 - Peer reviewed journal articlesResearchers 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.
4/1/2006 - Technology NewsThis publication is intended to promote awareness of float coal dust explosion hazards in the mining industry and offers a float coal dust mitigation technique.
9/1/2004 - Information CircularsThis report analyzes mine fires for all U.S. underground and surface coal mining categories by state and 2-year time periods during 1990-1999.
