• A Study of the Ground Control Effects of Mining Longwall Faces Into Open or Backfilled Entries
  1/1/2001 - Peer reviewed journal articles
  This paper summarizes case studies where unusual circumstances required that a longwall retreat into or through previously driven rooms. Two types of roof failure are identified and discussed.
• Best Practices to Mitigate Injuries and Fatalities from Rock Falls
  8/1/2000 - Conference papers, Safety guidelines, tips, and checklists
  This paper presents an overview of the most significant ground control hazards facing today's mineworkers, as well as best practices to reduce these risks.
• Technology News 482 - Ground Support Safety Training Video
  7/1/2000 - Technology News
  This video, entitled "Ground Support...It's Important, or Miner Mike Saves the Day," presents information on why ground supports work and how to install them properly.
• Determination of Physical Properties of Cable Bolts in Cement Grout Pull Tests Using Instrumented King Wires
  4/1/2000 - Conference papers
  Researchers are investigating the physical properties of cable bolts by replacing the conventional king wire with a modified king wire on which strain gauges have been installed.
• Creep Along Weak Planes in Roof and How It Affects Stability
  3/1/2000 - Conference papers
  A NIOSH study of the time-dependent response of rock stressed along weakness planes with the objective to improve mine safety by reducing the number of roof falls that cause injuries and fatalities to miners.
• Miner Mike Saves the Day! or Ground Support... It's Important!
  1/1/2000 - NIOSH/USBM numbered publications, Videos and multimedia
  This video teaches the necessity and use of ground supports.
• Design Methodology for Standing Secondary Roof Support in Longwall Tailgates
  8/1/1999 - Conference papers
  This paper discusses a design methodology for standing secondary tailgate supports, using the performance characteristics generated in the NIOSH Mine Roof Simulator (MRS) to match load characteristics of various supports to ground reaction behavior.
• 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.
• 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.
