• 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.
• CFD Modeling of Spontaneous Heating in a Large-Scale Coal Chamber
  7/1/2009 - Peer reviewed journal articles
  This paper discusses a study in which a three-dimensional CFD modeling of spontaneous heating of coal, based on the U.S. Bureau of Mines (USBM) large-scale coal chamber tests, was conducted.
• Stability Mapping to Examine Ground Failure Risk: A Field Study at a Limestone Mine
  7/1/2009 - Conference papers
