• EVADE Software
  4/7/2023 - PC software, Reports of Investigations
  EVADE 2.4 has been updated with expanded video and data features to make it a more generalized and powerful tool.
• Development of a Gas Monitor Simulator and Mine Rescue Contest Field Trials
  1/1/2012 - Peer reviewed journal articles
  NIOSH researchers completed field trials during coal mine rescue contests using simulated gas detectors in place of placards, and demonstrated that the newly developed GMS device may be used with no adverse impact on team contest performance.
• Seismic Network Operations at a Deep Underground Coal Mining District in Western Colorado (USA)
  8/1/2009 - Conference papers
  This paper describes network installation and methods used to collect, process, and distribute seismicity information collected on the surface above two longwall coal mines in western Colorado, and gives several examples of the collected data.
• Monitoring and Removal of CO in Blasting Operations
  12/1/2008 - Peer reviewed journal articles
  This paper discusses methods of preventing CO migration, lessening migrated CO, and detecting CO in underground enclosed spaces and may help reduce exposure of area residents to CO and help prevent unnecessary regulations and blasting limitations.
• Monitoring Coal Mine Seismicity with an Automated Wireless Digital Strong-Motion Network
  7/1/2008 - Conference papers
  This paper describes a seismic network installed in western Colorado in the vicinity of three underground coal mines, its features for user access to data, and then gives two examples of seismic events resulting in some damage to mine workings.
• 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.
• 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.
