3/1/2012 - Peer reviewed journal articlesThe CART-based model that is given in this paper can be used to predict methane emission rates and to adjust operation parameters under ventilation constrains in longwall mining.
3/1/2009 - Peer reviewed journal articlesThis study describes the development of an expert classification system used as a decision tool which can be used for degasification system selection using site- and mine-specific conditions.
A Numerical Evaluation on the Effects of Impermeable Faults on Degasification Efficiency and Methane Emissions During Underground Coal Mining9/1/2008 - Peer reviewed journal articlesThis study uses reservoir simulations to illustrate the effects of impermeable faults on the production performance of vertical and horizontal degasification boreholes.
9/1/2007 - Conference papersThis paper reviews how simultaneous application of three basic elements reduces the methane explosion hazard at coal mine working faces: (1) adequate ventilation, (2) regular monitoring of gas concentrations, and (3) elimination of ignition sources.
1/1/1994 - Information CircularsThis paper describes the history and technology of methane drainage in the US and other countries.
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.
Time-Lapse Analysis of Methane Quantity in the Mary Lee Group of Coal Seams Using Filter-Based Multiple-Point Geostatistical Simulation8/1/2013 - Peer reviewed journal articlesAn article examining the approach of using time-lapse methods to analyze the methane degasification of a group of coal mine seams in Alabama.
Coal Mine Methane: A Review of Capture and Utilization Practices with Benefits to Mining Safety and to Greenhouse Gas Reduction5/1/2011 - Peer reviewed journal articlesThis article reviews the technical aspects of coal mine methane (CMM) capture in and from coal mines, the factors affecting CMM accumulations in underground coal mines, methods for capturing methane using boreholes, and borehole designs.
1/1/2010 - Conference papersThis paper discusses several milestone events that show the progress of methane control research in underground coal mines.
11/1/2008 - Conference papersThis work by NIOSH has modelled the impacts of borehole pattern and design and the effects of increasing face length on gob gas venthole performance.
