• 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.
• A New Methane Control and Prediction Software Suite for Longwall Mines
  9/1/2011 - Peer reviewed journal articles
  This paper presents technical and application aspects of a new software suite, MCP (Methane Control and Prediction), developed for addressing some of the methane and methane control issues in longwall coal mines.
