1/1/1992 - Reports of InvestigationsReports on the U.S. Bureau of Mines development and testing of an instrinsically safe methane monitor based on differential absorption of infrared light.
2/18/2021 - Research areasMethane 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.
9/16/2020 - Research projectsA 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.
4/2/2020 - Research projectsA project to develop and implement workplace solutions to reduce miners’ overexposure to hazardous airborne contaminants emitted from diesel-powered equipment.
11/1/2019 - Non-peer reviewed journal articlesAn article discussing NIOSH's research on gas well stability in longwall pillars.
1/29/2019 - Research projectsA project to improve the capabilities to detect changing ventilation conditions along a longwall face arising from poor roof caving characteristics and increasing face length.

9/27/2018 - Peer reviewed journal articlesAn 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.
8/1/2018 - Peer reviewed journal articlesA 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.
2/1/2018 - Peer reviewed journal articlesA 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.
