2/1/2001 - Conference papersPast studies with blowing face ventilation systems have shown that using a machine-mounted scrubber and water sprays can reduced methane levels at the face.
Study of toxic fumes produced by the detonation of ANFO/emulsion blends. An extension of previous ANFO fumes production research that includes an emulsion blasting agent.
This 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.
The 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.
