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.
9/1/2009 - Reports of InvestigationsThe information in this report was used by MSHA and WVOMHS&T as supporting data in their analyses and investigative reports of the Sago Mine explosion.
Evaluation of Explosion-Resistant Seals, Stoppings, and Overcast for Ventilation Control in Underground Coal Mining12/1/2002 - Reports of InvestigationsEvaluation of the strength characteristics and air leakage resistance of numerous innovative seal designs and ventilation control structures for use in underground coal mines.
8/1/1999 - Reports of InvestigationsNIOSH cooperated with Tecrete Industries Pty. Ltd. and BHP Australia Coal to evaluate the strength characteristics and air leakage of four seal and two stopping designs for use in underground coal mines.
1/1/1996 - Reports of InvestigationsStrength characteristics and air leakage resistance of seals and designs of water traps used in underground coal mines were evaluated in a joint effort by the Pittsburgh Research Center and the Mine Safety and Health Administration.
11/1/1995 - Reports of InvestigationsLaboratory and field testing results are presented for reducing dust and/or gas ignitions associated with blasting operations in oil shale and sulfide ore mining applications.
1/1/1992 - Reports of InvestigationsThe Bureau of Mines tangentially impacted potential coal-cutter bit shank materials against sandstone to investigate the potential of the materials to ignite natural gas by a friction-generated hot streak.
1/1/1992 - Reports of InvestigationsThe Bureau of Mines completed an investigation of the influence of material on the ignition probability using the breakflash apparatus. This report presents results of an investigation into the influence of disk electrode material on the probability of...
1/1/1990 - Reports of InvestigationsThe Bureau of Mines has developed an acoustic test for determining if a rock salt sample is from a "normal" nongassy salt face or from a gassy face where an outburst has the potential to occur.
1/1/1988 - Reports of InvestigationsThe Bureau of Mines conducted an investigation into the occurrence of outbursts of salt known to be responsible for explosions, fatalities, and damage in domal salt mines. The purpose of the investigation was to develop a basis for predicting these outb...
