• 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.
• Methane-Air Mixtures Ignited by CW Laser-Heated Targets on Optical Fiber Tips: Comparison of Targets, Optical Fibers, and Ignition Delays
  9/1/2006 - Peer reviewed journal articles
  Researchers conducted experiments to estimate the mean and standard deviation of laser powers needed to ignite 6% methane-air atmospheres using single-mode optical fiber tips covered by two types of iron oxide mixed with a ceramic adhesive.
• 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.
• Technology News 515 - Float Coal Dust Explosion Hazards
  4/1/2006 - Technology News

• 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.
• Behavior of Nitrogen Oxides in the Product Gases from Explosive Detonations
  1/1/2006 - Conference papers
  Toxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In this study, 10 lb. charges of confined blasting agent were detonated in a closed chamber, and then detonation gases were analyzed.
