• 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.
• Detrimental Effects of Capacitance on High-Resistance-Grounded Mine Distribution Systems
  9/1/2006 - Peer reviewed journal articles
  There 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.
• CFD Modeling of Fire Spread Along Combustibles in a Mine Entry
  3/1/2006 - Conference papers
  A 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.
• Operationalizing Normal Accident Theory for Safety-Related Computer Systems
  11/1/2005 - Peer reviewed journal articles
  Normal 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.
• Variation of Horizontal Stresses and Strains in Mines in Bedded Deposits in the Eastern and Midwestern United States
  8/1/2003 - Conference papers
  This paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
• Computational Research
  11/1/2021 - Research projects
  A project to contribute to improving the health and safety of miners by providing essential information technology development activities for the NIOSH Mining Program.
• Mapping of Compositional Properties of Coal Using Isometric Log-Ratio Transformation and Sequential Gaussian Simulation - A Comparative Study for Spatial Ultimate Analyses Data
  3/1/2019 - Peer reviewed journal articles
  An article on mapping the ultimate analyses parts of the Springfield coal from an Indiana section of the Illinois basin, using sequential Gaussian simulation of isometric log-ratio transformed compositions.
• Empirical Engineering Models for Airborne Respirable Dust Capture from Water Sprays and Wet Scrubbers
  12/1/2018 - Peer reviewed journal articles
  An article presenting a dimensionless empirical model developed for predicting airborne dust capture efficiency of water sprays and wet scrubbers.
• Numerical and Experimental Investigation of Carbon Monoxide Spread in Underground Mine Fires
  9/27/2018 - Peer reviewed journal articles
  An article describing an evaluation of MFIRE, a mine fire simulation software based on ventilation networks, for its carbon monoxide spread prediction capabilities using experimental results from large-scale diesel fuel and conveyor belt fire tests.
• Temperature Rise Within a Mobile Refuge Alternative (RA) - Experimental Investigation and Model Validation
  6/1/2017 - Peer reviewed journal articles
  An article by NIOSH that describes the results from heat and relative humidity testing in a 10-person, tent-type mobile refuge alternative.
