10/1/2004 - Conference papersThe NIOSH mining research program at the Pittsburgh Research Laboratory (PRL) includes the areas of coal mine dust control and monitoring, and explosion prevention.
-
5/1/2004 - Conference papersThis study describes how response times of machine-mounted methane monitors were measured by placing the methane sensor heads in a specially designed box where they were exposed to an atmosphere containing a constant concentration of methane.
-
10/1/2002 - Conference papersThis paper addresses the question, 'Can lightning cause potential differences capable of igniting methane-and-air mixtures at overburden depths at which underground coal mining occurs?'
-
6/1/2002 - Conference papersThis publication examines a procedure for measuring the response time of machine-mounted methane monitors
-
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.
-
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.
-
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.
