• 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.
• 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...
• 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.
• Problems Facing Coal Mining and Gas Production in the Hartshorne Coalbeds of the Western Arkoma Basin, OK
  12/1/1983 - Reports of Investigations
  Major problems facing the development of coal and gas resources of the Hartshorne Coalbeds include the complex distribution of minable and unminable coal, high methane content and bed pressure, faulting, variations in degree of dip, presence of natural ...
• Sulfur Hexafluoride as a Mine Ventilation Research Tool - Recent Field Applications
  12/1/1982 - Reports of Investigations
  Sulfur hexafluoride (SF6) is an odorless, colorless, nontoxic gas that has found acceptance as a tracer gas in research on ventilation patterns, measurement of air leak rates, respirable dust reductions due to bagging hood modifications, and the study o...
• Face Ventilation Measurement with Sulfur Hexafluoride (SF6)
  1/1/1980 - Reports of Investigations
  The face ventilation measurement method developed by the Bureau of Mines involves releasing a small volume of tracer gas (SF6) on the off-curtain side of the working face at the start of the mining cycle.
• Three Coal Mine Ventilation Studies Using Sulfur Hexafluoride Tracer Gas
  1/1/1976 - Reports of Investigations
  This report describes three coal mine ventilation studies by the Bureau of Mines in which sulfur hexafluoride (SF6) was used as a tracer gas.
• Tracer Gas as an Aid in Mine Ventilation Analysis
  1/1/1974 - Reports of Investigations
  The Bureau of Mines has successfully used sulfur hexafluoride (SF6) as a tracer gas to measure mine air flows under conditions where conventional methods have failed. SF6 was employed experimentally to measure accurately recirculation of return into int...
• Using Sulfur Hexafluoride as a Gaseous Tracer to Study Ventilation Systems in Mines
  1/1/1974 - Reports of Investigations
  The Bureau of Mines found sulfur hexafluoride (SF6), released from a lecture bottle, to be an ideal gaseous tracer for studying mine ventilation systems. In a Pennsylvania limestone mine, this technique was useful in evaluating the effectiveness of auxi...
