• Methane Drainage and Migration
  1/17/2020 - 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.
• 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.

• 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.
• Effects of FAME Biodiesel and HVORD on Emissions from an Older Technology Diesel Engine
  12/1/2017 - Peer reviewed journal articles
  A paper comparing the potential of FAME biodiesel and HVORD as a control strategy to reduce the exposure of underground miners to aerosols and gases emitted by diesel-powered equipment.
• Simultaneously Reducing CO2 and Particulate Exposures via Fractional Recirculation of Vehicle Cabin Air
  7/1/2017 - Peer reviewed journal articles
  An article presenting research on fractional recirculation as a simple method to reduce exposures to particulate matter and CO2 in vehicles.
• Intrinsically Safe Low-Power Methane Wireless Sensors for Mapping of Methane Gas Clouds
  11/28/2016 - Contracts and cooperative agreements
  A contract to develop intrinsically safe, low-power-consumption methane sensors for mapping of methane gas clouds accumulated in underground coal mines.
• Wireless Sensor Network with Methane Gas Cloud Detector and Absolute Pressure Sensor
  11/28/2016 - Contracts and cooperative agreements
  A contract to (1) conduct absolute pressure measurement and recording in both non-permissable and permissable areas of a coal mine and (2) explore methane gas cloud detection, measurement, and visualization.
