• Knowledge Management and Transfer for Mine Emergency Response
  9/1/2006 - Peer reviewed journal articles
  US coal mining organizations are losing the knowledge they need to be able to respond to emergencies. Knowledge management provides a useful perspective from which to view the problem. Knowledge can be managed by cultivating it through narratives.
• Prediction of Longwall Methane Emissions and the Associated Consequences of Increasing Longwall Face Lengths: A Case Study in the Pittsburgh Coalbed
  6/1/2006 - Conference papers
  NIOSH conducted a study with the goal of characterizing methane emissions from increasing face lengths in the Pittsburgh Coalbed and providing a method of predicting emissions increases from longer faces and of planning for more methane control.
• Predicting Methane Emissions from Longer Longwall Faces by Analysis of Emission Contributors
  6/1/2006 - Conference papers
  NIOSH conducted a longwall methane emission and mining time study at a Pittsburgh Coalbed mine to predict emissions from a longer face, and developed and applied mathematical formulas and constants to characterize four emission contributors.
• CFD Modeling of Fire Spread Along Combustibles in a Mine Entry
  3/1/2006 - Conference papers
  A computational fluid dynamics (CFD) program was applied to fire spread along combustibles in a ventilated mine entry. The rate of flame spread was evaluated for the ribs and roof of a coal mine entry, timber sets, and a conveyor belt.
• Fire Response Preparedness for Underground Mines
  1/1/2005 - Information Circulars
  This report deals with the preparedness of miners to respond to underground fires. It is intended to aid the mining industry in understanding the various roles of emergency responders and the training techniques used to increase their skill levels. The ...
• Evaluation of the SKC® DPM Cassette for Monitoring Diesel Particulate Matter in Coal Mines
  12/1/2004 - Peer reviewed journal articles
  A commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC®. Tests were conducted to evaluate the performance of the DPM Cassette for measuring diesel-source elemental carbon in the presence of coal dust.
• Analysis of Mine Fires for All U.S. Underground and Surface Coal Mining Categories: 1990-1999
  9/1/2004 - Information Circulars
  This report analyzes mine fires for all U.S. underground and surface coal mining categories by state and 2-year time periods during 1990-1999.
• Geologic Hazards and Roof Stability in Coal Mines
  10/1/2003 - Information Circulars
  This report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock include drawrock, rider coals, head coal, stackrock, and stream valley effects.
• Variation of Horizontal Stresses and Strains in Mines in Bedded Deposits in the Eastern and Midwestern United States
  8/1/2003 - Conference papers
  This paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
• Continuous Wave Laser Ignition Thresholds of Coal Dust Clouds
  8/1/2003 - Peer reviewed journal articles
  Laser-based instruments are used in areas where coal dust ignition presents a safety hazard. This NIOSH study determines when an optical beam may be considered a potential ignition source in underground coal mines or coal storage facilities.
