1/16/2024 - Research projectsA pilot project to determine the geological variables linked to high methane concentrations and increased mining-induced seismicity in underground coal mines.
-
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.
-
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.

-
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.
-
7/18/2016 - Contracts and cooperative agreementsA contract to extend communication and hazard monitoring into bleeders or other remote workings in an active underground coal mine.
-
7/16/2016 - Contracts and cooperative agreementsA contract to evaluate the practicality and permissibility of modern laser-based technology for remotely detecting and mapping potentially explosive methane accumulations.
