• 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.
• Toward Pillar Design To Prevent Collapse of Room-and-Pillar Mines
  2/1/2001 - Conference papers
  Three alternative approaches to reduce the risk of catastrophic collapse are described: containment, prevention, and full-extraction. Without good data available on post-failure pillar behavior, containment and full-extraction are the safest.
• Application of the Coal Mine Roof Rating (CMRR) to Extended Cuts
  4/1/1999 - Peer reviewed journal articles
  The Coal Mine Roof Rating (CMRR) has been widely accepted as a tool for geologic characterization and mine planning. The application of the CMRR to extended cuts (cuts greater that 6 m (20 ft) in length) is discussed.
• Proceedings: New Technology for Ground Control in Retreat Mining
  3/1/1997 - Information Circulars
  This proceedings volume contains papers presented at technology transfer seminars sponsored by the National Institute for Occupational Safety and Health (NIOSH) on New Technology for Ground Control in Retreat Mining.
• Calibrating the LaModel Program for Deep Cover Pillar Retreat Coal Mining
  9/18/2020 - Contracts and cooperative agreements
  West Virginia University will calibrate the LaModel Program to aid in projecting success and accuracy of design methodologies for safe retreat mining.
• Analysis of ARMPS2010 Database with LaModel and an Updated Abutment Angle Equation
  1/1/2020 - Peer reviewed journal articles
  A paper presenting a new equation for calculating accurate abutment angles for deeper mining cases. The new equation was tested using both ARMPS2010 and LaModel for the entire case history database of ARMPS2010.
• Coal Rib Response During Bench Mining: A Case Study
  5/1/2018 - Peer reviewed journal articles
  A study exploring the geomechanics of bench room-and-pillar mining and the associated response of high pillar ribs at overburden depths greater than 300 m.
• Assessing Elevated Stress Due to Full Extraction Mining
  1/16/2018 - Research projects
  A project to develop engineering-based stress analysis procedures for improved assessment of stress-related hazards due to full extraction mining.
• Geotechnical Considerations for Concurrent Pillar Recovery in Close-distance Multiple Seams
  1/1/2018 - Peer reviewed journal articles
  A paper addressing the geotechnical considerations for concurrent pillar recovery in two coal seams with 21 m of interburden under about 305 m of depth of cover.
• Respirable Dust Control Methods on Continuous Mining Operations
  3/15/2017 - Research projects
  A project to develop and evaluate control technologies to reduce respirable dust exposures for operators of roof bolters and continuous mining machines.
