• Remote Fiber-Optic Methane Monitor
  1/1/1992 - Reports of Investigations
  Reports on the U.S. Bureau of Mines development and testing of an instrinsically safe methane monitor based on differential absorption of infrared light.
• Methane Drainage and Migration
  2/18/2021 - Research areas
  Methane is an odorless, tasteless, colorless, lighter-than-air gas formed by the decomposition of organic and other carbonaceous materials. From 5% to 15% can form an explosive mixture which, if ignited, can have catastrophic consequences.
• Stability Evaluation of Active Gas Wells in Longwall Abutment Pillars
  9/16/2020 - Research projects
  A project to evaluate and quantify subsurface overburden deformations in longwall abutment pillars under shallow overburden depths, and to employ field instrumentation results and 3D numerical modeling to identify critical parameters.
• Advanced Strategies for Controlling Exposures to Diesel Aerosols
  4/2/2020 - Research projects
  A project to develop and implement workplace solutions to reduce miners’ overexposure to hazardous airborne contaminants emitted from diesel-powered equipment.
• Evaluating the Stability of Shale Gas Wells in Longwall Barrier Pillars
  11/1/2019 - Non-peer reviewed journal articles
  An article discussing NIOSH's research on gas well stability in longwall pillars.
• Ventilation of Longwall Faces
  1/29/2019 - Research projects
  A project to improve the capabilities to detect changing ventilation conditions along a longwall face arising from poor roof caving characteristics and increasing face length.

• Numerical and Experimental Investigation of Carbon Monoxide Spread in Underground Mine Fires
  9/27/2018 - Peer reviewed journal articles
  An article describing an evaluation of MFIRE, a mine fire simulation software based on ventilation networks, for its carbon monoxide spread prediction capabilities using experimental results from large-scale diesel fuel and conveyor belt fire tests.
• Estimation of Metabolic Heat Input for Refuge Alternative Thermal Testing and Simulation
  8/1/2018 - Peer reviewed journal articles
  A paper describing a study where miner size and activity level were used to determine the metabolic heat rate, oxygen requirements and carbon dioxide generation that are representative of miners in a refuge situation.
• CFD Gas Distribution Analysis for Different Continuous-miner Scrubber Redirection Configurations
  2/1/2018 - Peer reviewed journal articles
  A study in which a series of models using computational fluid dynamics (CFD) were used to examine gas distribution around a continuous miner with various fan-powered flooded bed scrubber discharge configurations in an exhaust curtain working face.
