7/24/2020 - PC softwareTry the newly rewritten version of the MFIRE software program to model fire and contaminant spread in underground mines.
3/27/2014 - Reports of InvestigationsThis Report of Investigations details the results of a NIOSH investigation of temperature rise in mobile refuge alternatives.
3/1/2012 - Technology NewsNIOSH completed a major redesign of MFIRE and replaced its outdated programming language with an object-oriented C++ approach. The program was split into a front-end with a simple graphical-user-interface (GUI), and the MFIRE “engine” back-end.
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.
7/1/2010 - Conference papersThe paper provides a basic set of input data and a modeling approach that can be used for numerical modeling investigations of various coal mine designs using the FLAC3D software package.
3/1/2010 - Peer reviewed journal articlesIn this paper, Computational Fluid Dynamics modeling of the effect of longwall face advance on the spontaneous heating of coals in a two-panel gob area using a bleeder ventilation system is presented.
Forecasting Gob Gas Venthole Production Performances Using Intelligent Computing Methods for Optimum Methane Control in Longwall Coal Mines9/1/2009 - Peer reviewed journal articlesIn 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.
7/1/2009 - Peer reviewed journal articlesThis 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.
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.
11/1/2008 - Conference papersThis article discusses how narrative-based training has evolved and is likely to continue changing in the future using the Underground Coal Mine Map Reading Training (UCMMRT) developed by NIOSH.
