• Rock Mechanics Study of Lateral Destressing for the Advance-and-Relieve Mining Method
  8/1/2003 - Conference papers
  The advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
• Exploration of Two Position Adjustment Methods for Underground Mine Tracking Systems
  1/1/2009 - Conference papers
  This paper introduces two position adjustment methods for mine tracking systems which use a coplanar node-path network mine model as the foundation for their development.
• Evaluation of the Impact of Standing Support on Ground Behavior in Longwall Tailgates
  8/1/2005 - Conference papers
  The conclusion drawn from this study was that standing supports do not have sufficient capacity to control main roof or floor loading or prevent the resulting convergence of the tailgate entry.
• Experimental and Modeling Investigation of the Effect of Ventilation on Smoke Rollback in a Mine Entry
  2/1/2005 - Conference papers
  Diesel fuel fire experiments were conducted to determine the critical air velocity for preventing smoke rollback. Experimental results compared very well with model predictions based upon a computational fluid dynamics (CFD) fire dynamics simulator.
• Evaluation of the Bagged Stone Dust Barrier Effectiveness in a Bord and Pillar Mine
  6/1/2001 - Conference papers
  A project to evaluate the South African bagged stone dust explosion barrier was successfully completed at the NIOSH Lake Lynn Experimental Mine.
