• 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.
• Evaluation of Smoke Detectors for Mining Use
  1/1/1995 - Reports of Investigations
  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.
• Evaluation of Catalyzed Diesel Particulate Filters Used in an Underground Metal Mine
  1/1/1993 - Reports of Investigations
  Catalyzed 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.
• Hybrid Fiber-Optic Electrochemical Carbon Monoxide Monitor
  1/1/1992 - Reports of Investigations
  The 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.
• 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.
• Gas-Sampling Capability of Vacutainers
  1/1/1978 - Reports of Investigations
  Tests were conducted to study shelf life of evacuated vacutainer samplers prior to sampling and also to check the stability of sampled gases prior to analysis.
