• Controlling Roof Beam Failures From High Horizontal Stresses in Underground Stone Mines
  8/1/1998 - Conference papers
  A design technique is presented which provides stone miners with a method for making stability assessments. The consequences of widening rooms, changing geology and horizontal stresses, and different rock bolts on roof beam failure are discussed.
• A Method for Evaluating System Interactions in a Dynamic Work Environment
  1/1/1997 - Conference papers
  Discusses a methodology to evaluate the causes of mishaps to develop recommendations to enhance safety. A specific case involves implementation of remotely controlled equipment in extended cut mining.
• Assessing the Effects of Virtual Emergency Training on Mine Rescue Team Efficacy
  11/1/2015 - Conference papers
  A conference paper describing a study that represents the first documented empirical attempt at evaluating the effectiveness of virtual reality training for mine rescue teams in the United States.
• Assessing the Safety Culture of Underground Coal Mining: Results and Recommendations
  2/23/2014 - Conference papers
  This manuscript details the process undertaken by researchers at the National Institute for Occupational Safety and Health Office of Mine Safety and Health Research to assess the safety culture at five underground coal mines across the United States.
• Are lithium-ion cells intrinsically safe?
  11/1/2013 - Conference papers
  A NIOSH study investigating the potential for lithium-ion battery thermal runaway from an internal short circuit in equipment approved as permissible for use in underground coal mines.
• Estimating the Performance of Sound Restoration Hearing Protectors using the Speech Intelligibility Index
  11/1/2010 - Conference papers
  To assess benefits of hearing protection devices for prevention of noise-induced hearing loss in miners, NIOSH tested the impact of nine electronic sound restoration hearing protectors on speech intelligibility in selected mining background noises.
• Characteristics of Gait in Restricted Vertical Space Versus Unrestricted Walking
  9/1/2010 - Conference papers
  This study assessed the difference between free cadence walking versus stoopwalking (under a 1.2-m ceiling), four-point crawling (hands and knees), and two-point crawling (knees only), both with and without kneepads.
• Determining Flame Travel Measurements from Experimental Coal Dust Explosions
  9/1/2010 - Conference papers
  NIOSH conducted large-scale explosion experiments at the Lake Lynn Experimental Mine to investigate the inerting effect of limestone rock dust. Flame travel was measured using a conventional test and results were compared to a newer method.
• An Analysis of Injuries to Haul Truck Operators in the U.S. Mining Industry
  9/1/2010 - Conference papers
  The objective of this work was to profile injuries sustained during haul truck operations, to identify priorities for further investigation, and to determine potential injury prevention strategies.
• An Economic Justification for the Implementation of Interventions that Reduce Knee Injuries in Underground Mining
  9/1/2010 - Conference papers
  To encourage mining companies to implement knee injury training programs and interventions, NIOSH performed an analysis of workers’ compensation data for one underground coal mine in Illinois and six in Pennsylvania.
