• Diesel Aerosols and Gases in Underground Mines: Guide to Exposure Assessment and Control
  10/1/2011 - Guides and manuals, Reports of Investigations
  A comprehensive guide to establish a program to curtail diesel particulate matter emissions, control pollutants after release in an underground mine environment and reduce exposures using administrative controls.
• Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 2004
  8/1/2006 - Reports of Investigations
  This 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.
• Optically Powered Remote Gas Monitor
  1/1/1995 - Reports of Investigations
  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.
• Performance Comparison of Rescue Breathing Apparatus
  10/1/1999 - Reports of Investigations
  A 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 Systems
  10/1/1999 - Reports of Investigations
  An 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...
• A 20-Liter Furnace Test Method to Determine the Combustion Gas Toxicity of Conveyor Belts
  1/1/1996 - Reports of Investigations
  Pittsburgh 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.
• Detection and Control of Spontaneous Heating in Coal Mine Pillars-A Case Study
  1/1/1995 - Reports of Investigations
  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 ...
• Evaluation of Alternative Placement of Longwall Gob Gas Ventholes for Optimum Performance
  1/1/1994 - Reports of Investigations
  Production trends were analyzed for 82 gob gas ventholes on 7 longwall panels in the Lower Kittanning Coalbed, Pennsylvania.
• Rapid (Grab) Sampling During Full-scale Explosions - Microscopic and Analytical Evaluation
  1/1/1988 - Reports of Investigations
  The Bureau of Mines has developed a system using a high-speed electropneumatic mechanism for the rapid (grab) sampling of dusts and gases during an explosion to monitor pyrolysis-charring in coal particles and combustion of pyrolysis vapors.
• Gas Content Determinations of Salt Samples Using Acoustic Responses
  1/1/1987 - Reports of Investigations
  The Bureau of Mines has developed a practical methodology for determining occluded gas contents of domal rock salt samples. The method, which is portable and fieldworthy, provides results in 5 min or less.
