11/1/2008 - Conference papersThis work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
-
6/1/2008 - Conference papersThis paper describes research conducted to compare the performance, including response time and accuracy, of selected instruments using infrared and catalytic sensors.
-
1/1/2005 - Conference papersThis paper describes test procedures used to evaluate performance of methane monitors that could be used underground for continuous personal monitoring of methane. The information in this report provides data that allow the reader to make side-by side c...

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.
-
5/1/1997 - Reports of InvestigationsAs the use of deep-cut mining increases, there is expected to be a greater demand for methane measurement devices capable of scanning working faces at depths in excess of 10 m to alert mine personnel of hazardous concentrations of methane and to satisfy...
-
9/1/1981 - Contract reportsThe purpose of this project was to enhance the Bureau of Mine's Cableless Electronic Survey System use to aid in the drilling of long boreholes in coal as part of the methane drainage program. The system that was ultimately developed was field tested an...
