• 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.
• Empirical Guidelines for Longwall Ground Control Design
  10/22/2016 - Research projects
  A project to update the database of case histories upon which the Analysis of Longwall Pillar Stability (ALPS) software bases its recommended stability factors.
• Longwall Shield Recovery Using Mobile Roof Supports
  7/1/2007 - Conference papers
  This paper addresses both the safety and the operational issues associated with mobile roof support (MRS) usage during shield recovery. It also discusses new developments, including the use of the inherently safer battery powered MRS's.
• Evaluation of Pillar Recovery in Southern West Virginia
  8/1/2002 - Conference papers
  Studies have identified a number of factors for evaluating a pillar extraction plan. This paper discusses each of the factors, presents relevant accident statistics, and shows how the risk factors can be combined to estimate the overall hazard.
• Field Evaluation of Mobile Roof Support Technologies
  8/1/2001 - Conference papers
  A historic overview of the role of mobile roof support (MRS) technologies in improving stability and worker safety is presented along with field evaluations of the MRS load rate monitoring device and other remote deformation-monitoring techniques.
• Mobile Roof Support Load Rate Monitoring System
  10/1/1999 - Conference papers
  A Mine Safety and Health Administration-permissible load rate monitoring system was developed.
• An Overview of Geomechanics Safety Research on Mobile Roof Supports
  1/1/1999 - Conference papers
  A study on the mechanics of strata behavior determined through extensive field measurements. Practical techniques for assessing roof behavior were developed along with a prototype remote controlled roof support system.
• Analysis of the Interaction Between Mobile Roof Supports and Mine Strata
  11/1/1998 - Conference papers
  To provide a better understanding of the mechanics of strata deformation, the authors have collected and reviewed measurements of convergence and stress in one western U.S. mine and have completed modeling for two typical pillar-pulling plans.
