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.
-
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.
-
11/22/2016 - 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.
