• EVADE Software
  6/12/2023 - 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.
• Benchmarking Longwall Dust Control Technology and Practices
  9/1/2011 - Peer reviewed journal articles
  Results from the NIOSH underground dust surveys and current longwall dust control technology and operating practices are discussed.
• Evaluation of Face Dust Concentrations at Mines Using Deep-Cutting Practices
  1/1/2011 - Reports of Investigations
  Dust surveys determined if deep-cut mining expose face workers to higher levels of respirable dust. Study findings indicate that levels on bolting faces did not appear to be affected by longer cycles associated with deep-cut mining practices.
• Rock Dusting Considerations in Underground Coal Mines
  6/1/2010 - Conference papers
  This paper discusses factors that could result in a potential undetected dust explosion hazard, when using current dust sampling procedures, in an area that otherwise appears to be adequately protected with rock dust.
• 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.
• Comparative Analysis of Moisture Sensitivity Index Tests for Coal Mine Roof
  2/1/2009 - Conference papers
  This paper describes the work NIOSH has completed in evaluating three moisture-sensitivity index tests on roof rocks from 23 U.S. coal mines.
• 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.
• Working in the Classroom - A Vision of Miner Training in the 21st Century
  11/1/2008 - Conference papers
  This article discusses how narrative-based training has evolved and is likely to continue changing in the future using the Underground Coal Mine Map Reading Training (UCMMRT) developed by NIOSH.
• 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.
