This NIOSH publication demonstrates how existing and new engineering controls can be used to reduce face methane levels.
Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 20048/1/2006 - Reports of InvestigationsThis study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
1/1/1992 - Reports of InvestigationsReports on the U.S. Bureau of Mines development and testing of an instrinsically safe methane monitor based on differential absorption of infrared light.
1/1/1996 - Reports of InvestigationsPittsburgh Research Center conducted experiments with mine conveyor belt samples in a 20-L furnace and in a laboratory fire tunnel to measure and compare the major toxic gas concentrations evolved during the combustion of the materials.
1/1/1995 - Reports of InvestigationsThe U.S. Bureau of Mines has constructed a smoke chamber and developed sensitivity tests for smoke detectors. Evaluation of six smoke detectors showed their potential for use as mine fire sensors or as part of a mine atmospheric monitoring system.
1/1/1993 - Reports of InvestigationsCatalyzed diesel particulate filters (CDPFs) reduce the concentration of diesel particulate matter (DPM) and may reduce the emissions of carbon monoxide (CO) and hydrocarbons (HC) in diesel exhaust.
1/1/1992 - Reports of InvestigationsThe U.S. Bureau of Mines has developed an intrinsically safe carbon monoxide (CO) monitoring system for mines by coupling a fiber-optic data telemetry system with a prototype electrochemical CO monitor.
1/1/1989 - Reports of InvestigationsThe U.S. Bureau of Mines used a contact drilling strategy with short-collared assemblies in order to rotary drill long horizontal methane drainage holes in the Beckley coalbed near Glen Daniel, West Virginia. By decreasing the thrust and increasing the ...
1/1/1988 - Reports of InvestigationsThe Bureau of Mines conducted an investigation into the occurrence of outbursts of salt known to be responsible for explosions, fatalities, and damage in domal salt mines. The purpose of the investigation was to develop a basis for predicting these outb...
1/1/1988 - Reports of InvestigationsA Bureau of Mines geologic study of Pennsylvanian and Permian coalbeds in southwestern Pennsylvania was undertaken to determine the effects of coalbed geology and petrology on in situ coalbed gas contents.
