• A Study of First Moments in Underground Mine Emergency Response
  1/1/2010 - Peer reviewed journal articles
  What happens in the first crucial moments of a mine emergency? The study showed the importance of mine emergency planning and training, communication providing information for decision-making, leadership and trust, plus individual personal issues.
• Reconciling Longwall Gob Gas Reservoirs and Venthole Production Performances Using Multiple Rate Drawdown Well Test Analysis
  12/1/2009 - Peer reviewed journal articles
  In this paper, the production rate-pressure behaviors of six gob gas ventholes drilled over three adjacent panels were analyzed by using conventional multi-rate drawdown analysis techniques.
• Controlling Dust Exposures in Longwall Mining Utilizing A Simple Barrier
  12/1/2009 - Peer reviewed journal articles
  This investigation tested the feasibility of enhancing existing engineering dust controls by mounting a simple barrier on a longwall shearer that separated the operators from the cutting drums.
• Update on Refuge Alternatives: Research, Recommendations, and Underground Deployment
  12/1/2009 - Peer reviewed journal articles
