7/1/2001 - Peer reviewed journal articlesA number of ignition incidents involving mining and farm equipment have illustrated the surprising danger of drilling, cutting, or otherwise penetrating sealed compartments or frames that are filled with metal scrap for ballast.
6/1/2001 - Conference papersThis publication develops criteria for selecting the best machine locations for monitoring methane and gives recommendations for revising methane action levels for alternative sampling locations.
6/1/2001 - Conference papersResearch to determine how machine-mounted water sprays and a scrubber interact to reduce methane levels and what spray configurations provide the best face ventilation when used with a scrubber.
5/1/2001 - Conference papersThis paper covers the development of NIOSH's modified direct method to measure the gas content of coal samples.
5/1/2001 - Technology NewsNIOSH tech news report on an incident where CO generated from blasting at a strip mine migrated through the ground into a nearby home, poisoning the occupants.
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...
7/1/2000 - Peer reviewed journal articlesBecause of the need to provide short-term or real-time estimates of worker respirable dust exposure, porous foam may be a viable classification media for a low flow rate, disposable respirable dust sampler for use in the coal mining industry.
