7/24/2020 - PC softwareTry the newly rewritten version of the MFIRE software program to model fire and contaminant spread in underground mines.
3/1/2012 - Technology NewsNIOSH completed a major redesign of MFIRE and replaced its outdated programming language with an object-oriented C++ approach.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.
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.
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.
Modeling and Prediction of Ventilation Methane Emissions of U.S. Longwall Mines Using Supervised Artificial Neural Networks2/1/2008 - Peer reviewed journal articlesThis study proposes a principal component analysis (PCA) and artificial neural network (ANN)-based approach to predict the ventilation methane emission rates of U.S. longwall mines.
Development and Application of Reservoir Models and Artificial Neural Networks for Optimizing Ventilation Air Requirements in Development Mining of Coal Seams11/1/2007 - Peer reviewed journal articlesUsing coalbed methane reservoir modeling and an artificial neural network (ANN) design for prediction and optimization of methane inflows and ventilation air requirements to maintain methane concentrations below statutory limits.
9/1/2006 - Peer reviewed journal articlesThere are potential detrimental effects of capacitance charging currents during line-to-ground faults in mine power distribution systems. A representative mine power system is modeled, and simulations with faults at various locations are conducted.
3/1/2006 - Conference papersA computational fluid dynamics (CFD) program was applied to fire spread along combustibles in a ventilated mine entry. The rate of flame spread was evaluated for the ribs and roof of a coal mine entry, timber sets, and a conveyor belt.
11/1/2005 - Peer reviewed journal articlesNormal Accident Theory is a classic argument in organizational sociology, although it has been criticized as having imprecise definitions and lacking criteria for quantifying complexity. These limitations are addressed by a unique approach.
