• A CART Technique to Adjust Production from Longwall Coal Operations under Ventilation Constraints
  3/1/2012 - Peer reviewed journal articles
  The 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.
• Forecasting Gob Gas Venthole Production Performances Using Intelligent Computing Methods for Optimum Methane Control in Longwall Coal Mines
  9/1/2009 - Peer reviewed journal articles
  In this paper, the total gas flow rates and methane percentages from 10 GGVs were analyzed. The results showed that the two-hidden layer model predicted total production and the methane content of the GGVs with more than 90% accuracy.
• Degasification System Selection for U.S. Longwall Mines Using an Expert Classification System
  3/1/2009 - Peer reviewed journal articles
  This 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 Mining
  9/1/2008 - Peer reviewed journal articles
  This study uses reservoir simulations to illustrate the effects of impermeable faults on the production performance of vertical and horizontal degasification boreholes.
• Methods for Controlling Explosion Risk at Coal Mine Working Faces
  9/1/2007 - Conference papers
  This 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.
• Methane Control for Underground Coal Mines
  1/1/1994 - Information Circulars
  This paper describes the history and technology of methane drainage in the US and other countries.
• Methane Drainage and Migration
  2/18/2021 - Research areas
  Methane 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.
• Analysis of Gob Gas Venthole Production Performances for Strata Gas Control in Longwall Mining
  3/1/2018 - Peer reviewed journal articles
  An article about a study to analyze production performances of gas gov ventholes drilled over a longwall panel as a methane control measure.
• Time-Lapse Analysis of Methane Quantity in the Mary Lee Group of Coal Seams Using Filter-Based Multiple-Point Geostatistical Simulation
  8/1/2013 - Peer reviewed journal articles
  An article examining the approach of using time-lapse methods to analyze the methane degasification of a group of coal mine seams in Alabama.
• Integration of Vertical and In-Seam Horizontal Well Production Analyses with Stochastic Geostatistical Algorithms to Estimate Pre-Mining Methane Drainage Efficiency from Coal Seams: Blue Creek Seam, Alabama
  7/1/2013 - Peer reviewed journal articles
  An article detailing the extent to which it can be estimated that boreholes helped to degasify the Blue Creek coal seam in Alabama in advance of mining the seam.
