• Reduced Workers’ Compensation Costs With Roof Screening
  9/1/2012 - Peer reviewed journal articles
  This paper quantifies potential savings in WC premiums due to a reduction in rock fall injuries after roof screening in Pennsylvania’s underground coal mines. Two hypothetical mines with realistic injury and WC premium estimates were used.
• Potential of Roof Screening to Reduce Workers' Compensation Cost
  12/1/2010 - Peer reviewed journal articles
  Many rock fall injuries can be prevented with roof screen, but many coal mines are reluctant to use it due to added cost. This study looked at potential savings in workers' compensation premiums due reduced rock fall injuries after roof screening.
• External L5-S1 Joint Moments When Lifting Wire Mesh Screen Used to Prevent Rock Falls in Underground Mines
  9/1/2009 - Peer reviewed journal articles
  This study uses biomechanical modeling to estimate external moments about L5-S1 for sixteen lifting tasks, using two sizes of wire mesh screens, and presents recommendations to reduce spine loading.
• Diagnosing and Controlling Moisture-Sensitive Roof in Coal Mines
  1/1/2008 - Peer reviewed journal articles
  Moisture-sensitive roof rocks have contributed to time-dependent roof falls. NIOSH research proves the value of a wet/dry cycling test for rock evaluation.
• 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.
• Evaluation of Stress-control Layout at the Subtropolis Mine, Petersburg, Ohio
  1/1/2020 - Peer reviewed journal articles
  A paper detailing the positive aspects, as well as the challenges, of implementing a new stress-control mine layout.
• Ground Response to High Horizontal Stresses During Longwall Retreat and its Implications for Longwall Headgate Support
  2/19/2019 - Peer reviewed journal articles
  An article discussing roof support requirements in the longwall headgate under high horizontal stress in regard to the pattern of supplemental cable bolts and the critical locations where additional supplemental support is necessary.
• Shale Failure Mechanics and Intervention Measures in Underground Coal Mines: Results from 50 Years of Ground Control Safety Research
  2/1/2016 - Peer reviewed journal articles
  A report presenting a historical narrative on the research the National Institute for Occupational Safety and Health has conducted in relation to rock mechanics and shale.
• Roof Instability: What Reportable Noninjury Roof Falls in Underground Coal Mines Can Tell Us
  3/1/2014 - Peer reviewed journal articles
  An article examining the large body of noninjury roof fall reports in order to gain insight into the characteristics of roof falls in coal mines.
• Roof and Rib Fall Incident Trends: a 10-Year Profile
  1/1/2012 - Peer reviewed journal articles
  A comprehensive analysis of these events was conducted to better understand where and why these incidents occurred.
