• Preventing Injuries Caused by Unrecognized Stone Mine Roof Beam Failures With a Pro-Active Roof Control Plan
  3/1/1999 - Conference papers
  To help mitigate the potential for falls-of-ground injuries to underground stone miners, NIOSH developed the Roof Monitoring Safety System (RMSS) to aid in monitoring dangerous levels of roof beam deflection.
• Rock Falls - Preventing Rock Fall Injuries in Underground Mines
  1/1/1999 - NIOSH/USBM numbered publications, Videos and multimedia
  This video teaches the importance of proper roof scaling in underground mining to avoid injury and improve work conditions.
• Technology News 476 - Instrumented King Wire for Monitoring Cable Bolts
  11/1/1998 - Technology News
  Development of methods and tools to assist in the evaluation and selection of rock supports could reduce the number of unplanned rock falls significantly.
• Advances in Remote Sensing Techniques for Monitoring Rock Falls and Slope Failures
  8/1/1998 - Conference papers
  This paper describes the potential adaption of systems such as interferometric synthetic aperture radar, imaging spectroscopy, and time-domain reflectometry, to slope monitoring and design.
• Factors Influencing Intersection Stability in U.S. Coal Mines
  8/1/1998 - Conference papers
  Based on field investigations and a U.S. coal mines database containing 12 mines and 639 roof falls, NIOSH determines the factors that influence intersection instability and provides guidelines for the safe excavation and support of intersections.
• Proceedings of the Second International Workshop on Coal Pillar Mechanics and Design
  6/1/1998 - Information Circulars
  A collection of 15 papers from leading international ground control specialists. The papers address the entire range of issues associated with coal pillars and have a decidedly practical flavor.
• Roof and Rib Hazard Assessment for Underground Stone Mines
  1/1/1998 - Peer reviewed journal articles
  Roof and rib conditions were observed and assessed in 33 underground stone mines. It was found that selection of the mining horizon and mine layout decisions tremendously influence ground stability.
• International Experience with Longwall Mining into Pre-Driven Rooms
  1/1/1998 - Conference papers
  Unusual circumstances sometimes require a longwall retreat into/through a previously driven room, with the potential for failures and roof fall hazards. To determine the failure factors, NIOSH compiled an international database of 130 case histories.
• Roof Fall Entrapment: Eyewitness Account by Larry Strayer
  1/1/1992 - Training materials, Videos and multimedia
  A videotaped interview with a miner about a fall that occurred while he and another miner were attempting to bar down top just inby the last row of supports. An instructor's guide lets you use the video as part of an effective training session.
• Roof Fall Entrapment: Eyewitness Account by Dave Murone
  1/1/1992 - Training materials, Videos and multimedia
  A videotaped interview with Dave about the experience of recovering the body of a friend who was killed by a roof fall while under unsupported top.
