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.
-
9/1/2008 - Conference papersThis paper summarizes recent accomplishments in a research program that is addressing mine fire prevention, detection, management, and suppression, and provides an overview of the next phase of the NIOSH mine fire research program.
-
8/1/2008 - Peer reviewed journal articlesTo provide insights for the optimization of bleederless ventilation systems for U.S. underground coal mines, a computational fluid dynamics study was conducted to model spontaneous heating in longwall gob areas using a bleederless ventilation system.
-
7/1/2008 - Peer reviewed journal articlesThis paper updates an earlier report by the authors that studied electrical injuries from 1992 to 1998. The previous information is expanded and supplemented with fatal and nonfatal injury rates and trends through 2002.
-
6/1/2008 - Conference papersThe results of field tests to understand how ventilation and gob characteristics affect the spontaneous heating process causing spontaneous combustion fires in longwall or worked-out gob areas are presented.
-
1/1/2008 - Peer reviewed journal articlesMoisture-sensitive roof rocks have contributed to time-dependent roof falls. NIOSH research proves the value of a wet/dry cycling test for rock evaluation.
-
12/1/2007 - Peer reviewed journal articlesComputational Fluid Dynamics simulations were conducted to investigate the spontaneous heating of coals in longwall gob areas with different apparent activation energies and reaction surface areas. The results are reported in this paper.
-
10/1/2007 - Peer reviewed journal articlesThe top five priority hazards associated with underground coal mining equipment have been identified and information about potential contributing factors and controls collated.
-
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.
-
7/1/2007 - Guides and manuals, Information CircularsThis 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.
