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.
Many mines rely on toxic gas sensors to help maintain a safe and healthy work environment. This report describes a prototype monitoring system developed by the USBM that uses light to power and communicate with remote toxic gas sensors.
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.
10/1/1999 - Reports of InvestigationsA performance comparison of 14 rescue breathing apparatus was undertaken as an assessment of past and present worldwide technology. Rescue breathing apparatus are self-contained, closed-circuit breathing apparatus used for entry into areas having atmosp...
Prediction of Longwall Methane Emissions: An Evaluation of the Influence of Mining Practices on Gas Emissions and Methane Control Systems10/1/1999 - Reports of InvestigationsAn analysis of the consequences of increasing longwall panel dimensions, particularly face width, in gassy coalbeds. Continuous longwall face emission monitoring studies were conducted at two adjacent mines operating in the Pocahontas No. 3 Coalbed, whe...
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.
The 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.
This U.S. Bureau of Mines study examined spontaneous heating episodes in coal mine pillars in an active underground coal mine. The objective of this study was to discover if the location of future events of pillar spontaneous heating could be inferred ...
1/1/1994 - Reports of InvestigationsProduction trends were analyzed for 82 gob gas ventholes on 7 longwall panels in the Lower Kittanning Coalbed, Pennsylvania.
