1/17/2020 - 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.
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.
11/28/2016 - Contracts and cooperative agreementsA contract to develop intrinsically safe, low-power-consumption methane sensors for mapping of methane gas clouds accumulated in underground coal mines.
11/28/2016 - Contracts and cooperative agreementsA 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.
Integration of Sensing Technologies for Post-Event Monitoring of Hazardous Conditions in the Mining Environment11/22/2016 - Contracts and cooperative agreementsA contract to provide detection of ambient conditions in lesser traversed, remote areas of a mine by way of a repeater system with sensing modules capable of linking into the existing, hardened communications and tracking system.
