Relationship Between Radiated Seismic Energy and Explosive Pressure for Controlled Methane and Coal Dust Explosions in an Underground Mine3/1/2012 - Peer reviewed journal articlesThis paper describes the research conducted to quantify a relationship between measured values of radiated seismic energy and peak explosive pressure generated.
1/1/2012 - Peer reviewed journal articlesThis paper describes tests conducted to evaluate the effectiveness of the Barricade II Fire Blocking Gel.
1/1/2011 - Peer reviewed journal articlesThirteen 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.
1/1/2010 - Conference papersThis paper discusses several milestone events that show the progress of methane control research in underground coal mines.
1/1/2010 - Peer reviewed journal articlesThis 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.
9/1/2009 - Peer reviewed journal articlesThis study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.
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.
8/1/2009 - Peer reviewed journal articlesNIOSH conducted a statistical study of available data regarding frictional ignitions in the United States from 1983 to 2005 to determine and define conditions controlling their occurrence.
