• Investigation of induced recirculation during planned ventilation system maintenance
  10/1/2014 - Peer reviewed journal articles
  A report detailing ways to increase mine airflow to underground metal/nonmetal mine working areas to improve miners’ health and safety. One of those areas is controlled recirculation.
• Safety, Health, and Ventilation Cost Benefit Optimization with Simulation and Control
  8/4/2014 - Contracts and cooperative agreements
  A capacity-building contract to improve ventilation tasks in deep and hot underground mines to decrease injury risks; improve working conditions; meet occupational, environmental, and health standards; and reduce costs to stay competitive.
• Ventilation of Deep Open Pit Mines with Special Reference to Air Inversion in Arctic or Subarctic Regions
  7/17/2014 - Contracts and cooperative agreements
  A capacity-building contract to evaluate and enhance the atmospheric health and safety conditions in open pit mines, with special reference to air inversion in arctic or subarctic regions.
• Case Study of Controlled Recirculation at a Wyoming Trona Mine
  3/1/2014 - Peer reviewed journal articles
  A report detailing the results of two controlled recirculation tests over three days at a Wyoming trona mine, utilizing an inline booster fan to improve airflow to a remote and difficult-to-ventilate development section.
• CFD modelling of sampling locations for early detection of spontaneous combustion in long-wall gob areas
  1/1/2012 - Peer reviewed journal articles
  In this study, computational fluid dynamics (CFD) modeling was conducted to optimize gas sampling locations for the early detection of spontaneous heating in longwall gob areas.
• A New Methane Control and Prediction Software Suite for Longwall Mines
  9/1/2011 - Peer reviewed journal articles
  This paper presents technical and application aspects of a new software suite, MCP (Methane Control and Prediction), developed for addressing some of the methane and methane control issues in longwall coal mines.
• Validation of the Ventgraph Program for Use in Metal/Non-metal Mines
  6/1/2010 - Conference papers
  This study's goal was to validate the use of Ventgraph in a deep M/NM mine fire and illustrate its use as a valuable tool in mine ventilation, fire, and evacuation planning.
• Prediction of Porosity and Permeability of Caved Zone in Longwall Gobs
  3/1/2010 - Peer reviewed journal articles
  This work presents a fractal porous medium model to predict gob porosity and permeability for controlling methane flow and to predict air leakage into the gob.
• Methods to Improve Efficiency of Mine Ventilation Systems
  1/1/2010 - Peer reviewed journal articles
  This paper discusses some ways to find extra usable air when there is no extra ventilation capacity.
• Modeling Methane Emissions and Ventilation Needs by Examination of Mining Induced Permeability Changes and Related Damage to Ventilation Controls
  6/1/2009 - Conference papers
