• MFIRE
  7/24/2020 - PC software
  Try the newly rewritten version of the MFIRE software program to model fire and contaminant spread in underground mines.
• Investigation of Temperature Rise in Mobile Refuge Alternatives
  3/27/2014 - Reports of Investigations
  This Report of Investigations details the results of a NIOSH investigation of temperature rise in mobile refuge alternatives.
• Technology News 549 - MFIRE 3.0 - NIOSH Brings MFIRE into 21st Century
  3/1/2012 - Technology News
  NIOSH completed a major redesign of MFIRE and replaced its outdated programming language with an object-oriented C++ approach.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.
• 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.
• Numerical Model Calibration for Simulating Coal Pillars, Gob and Overburden Response
  7/1/2010 - Conference papers
  The 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.
• Effect of Longwall Face Advance on Spontaneous Heating in Longwall Gob Areas
  3/1/2010 - Peer reviewed journal articles
  In 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 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.
• 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.
• Working in the Classroom - A Vision of Miner Training in the 21st Century
  11/1/2008 - Conference papers
  This 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.
