1/1/2001 - Conference papersThis paper provides a brief overview of the ongoing study to evaluate the use of these chambers for pressure loading of full-scale seal designs using compressed air, water, or internal gas explosions.
1/1/2001 - Conference papersThe importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. While respirable dust can significantly affect the occupational health of underground coal miner, methane gas accumulations pose s...
2/1/2000 - Conference papersStudy of toxic fumes produced by the detonation of various ammonium nitrate/fuel oil (ANFO) mixtures and several cap-sensitive explosives.
2/1/1997 - Conference papersDeeper surface mining and deeper highwall penetration depths have lead to more frequent encounters with methane gas. While this coal is remotely mined from the surface, underground ignitions of methane have propagated to the surface and injured miners. ...
2/1/1997 - Conference papersResearch was conducted to investigate how ventilation of a mining face is affected when scrubber flow is greater or less than intake flow.
1/1/1997 - Conference papersTraditional techniques to experimentally determine toxic fumes produced by detonating high explosives are not applicable to blasting agents. To detonate properly, blasting agents require confinement, a significant booster, and other parameters.
