• The Borehole Monitoring Experiment: Field Measurements of Reservoir Conditions and Responses in Longwall Panel Overburden During Active Mining
  6/1/2008 - Conference papers
  This paper describes the results of a NIOSH borehole monitoring experiment (BME) on an active longwall panel.
• Equipment Noise and Worker Exposure in the Coal Mining Industry
  12/1/2006 - Information Circulars
  This study presents a NIOSH cross-sectional survey of noise sources and worker noise exposures, discusses the survey's application to administrative and engineering controls, and reviews exposure reduction methods.
• Laboratory and Field Performance of a Continuously Measuring Personal Respirable Dust Monitor
  9/1/2006 - Reports of Investigations
  This report includes the theory of operation, description, and the performance of the Personal Dust Monitor (PDM) compared to gravimetric-based reference dust sampling methods and laboratory verification of the instruments accuracy.
• Coal Dust Particle Size Survey of U.S. Mines
  8/1/2006 - Conference papers
  NIOSH and MSHA conducted a joint survey to determine the range of coal particle sizes found in dust samples collected from intake airways of U.S. coal mines.
• Computer Simulation of Ground Behaviour and Rock Bolt Interaction at Emerald Mine
  8/1/2004 - Conference papers
  This paper focuses on a computer simulation used to model roof behavior and rock bolt interaction in a collaborative study of ground behavior, reinforcement performance, and stress redistribution in a coal mine entry under severe horizontal stress.
• Self-Reported Musculoskeletal Symptoms Among Operators of Heavy Construction Equipment
  8/1/2003 - Conference papers
  This study assessed the adequacy of cab design and determined the percentage of musculoskeletal symptoms among operators of heavy construction equipment.
• Safer Mine Layouts for Underground Stone Mines Subjected to Excessive Levels of Horizontal Stress
  4/1/2003 - Peer reviewed journal articles
  At an underground stone mine, a modified stress-control mine layout is reducing hazardous conditions associated with excessive horizontal stress. Findings show that the layout provides more stable conditions, resulting in a safer working environment.
• Microseismic Activity Associated With a Deep Longwall Coal Mine
  2/1/2002 - Conference papers
  A deep longwall coal mine was instrumented with a 3-D microseismic system to help determine the exact strata mechanics associated with rock failure, redistribution of stress and associated gob formation from the longwall.
• Rock Damage Characterisation from Microseismic Monitoring
  7/1/2001 - Conference papers
  Outlines the concepts used to correlate rock failure with microseismic events and presents examples of microseismic monitoring together with associated computer modeling of the rock failure from several mine sites.
• Roof Monitoring Helps Prevent Injuries in Stone Mines
  11/1/2000 - Peer reviewed journal articles
  The Roof Monitoring Safety System (RMSS) is described, compared to other roof-monitoring technology, and described in context with proactive ground control plans for stone mines.
