• Best Practices and Bolting Machine Innovations for Roof Screening
  2/1/2003 - Conference papers, Safety guidelines, tips, and checklists
  Injury data show a dramatic reduction in roof skin injuries when screening is used. Five case studies in which roof screen was used are presented along with the costs of materials, impact on bolting advance rates, and potential ergonomic risks.
• Roof Screening: Best Practices and Roof Bolting Machines
  8/1/2002 - Conference papers, Safety guidelines, tips, and checklists
  Roof screening has been found to be very effective in controlling the fall of small rocks from the immediate roof surface. Data is presented from two mines that show a dramatic reduction in roof skin injuries when screening is used.
• Detecting Problems With Mine Slope Stability
  8/1/2002 - Conference papers
  Slope stability accidents are a leading cause of fatalities at U.S. surface mines. NIOSH is conducting research to reduce these fatalities. This paper presents some of the research and potential new technologies for slope monitoring and design.
• Emerging Technologies and the Future of Geotechnical Instrumentation
  7/1/2001 - Book chapters
  This paper discusses (1) the results of a ground-based hyperspectral imaging tool used to map the geology of an open-pit mine highwall, and (2) interferometric synthetic aperture radar and how it can be used in a variety of geotechnical situations.
• Technology News 483 - Safety Training Tools for Rock Scaling Personnel
  1/1/2001 - Technology News
  Scaling, the removal of loose rock from the roofs and walls of a mine by manual or mechanized means, may be necessary during any stage of mining. Manual scaling is very labor intensive, and mechanical methods can be too powerful and actually produce a l...
• 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.
• Coal Mine Bumps: Five Case Studies in the Eastern United States
  1/1/1987 - Information Circulars
  Information was collected at 5 bump-prone mines. Among the findings, two geologic conditions have been found to cause bumps in the eastern U.S.: relatively thick overburden and extremely rigid strata immediately above and below the mine coalbed.
