• CO and CO2 Emissions from Spontaneous Heating of Coal Under Different Ventilation Rates
  10/1/2011 - Peer reviewed journal articles
  This study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.
• Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine Air
  9/1/2009 - Peer reviewed journal articles
  This paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
• Monitoring and Removal of CO in Blasting Operations
  12/1/2008 - Peer reviewed journal articles
  This paper discusses methods of preventing CO migration, lessening migrated CO, and detecting CO in underground enclosed spaces and may help reduce exposure of area residents to CO and help prevent unnecessary regulations and blasting limitations.
• Threshold Powers and Delays for Igniting Propane and Butane-Air Mixtures by CW Laser-heated Small Particles
  11/1/2006 - Peer reviewed journal articles
  NIOSH researchers studied laser safety in potentially flammable environments. Researchers measured threshold igniting powers as a function of beam diameter for butane and propane-air mixtures by laser-heating targets placed on optical fiber tips.
• 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.
• Estimation of Metabolic Heat Input for Refuge Alternative Thermal Testing and Simulation
  8/1/2018 - Peer reviewed journal articles
  A paper describing a study where miner size and activity level were used to determine the metabolic heat rate, oxygen requirements and carbon dioxide generation that are representative of miners in a refuge situation.
• CFD Gas Distribution Analysis for Different Continuous-miner Scrubber Redirection Configurations
  2/1/2018 - Peer reviewed journal articles
  A study in which a series of models using computational fluid dynamics (CFD) were used to examine gas distribution around a continuous miner with various fan-powered flooded bed scrubber discharge configurations in an exhaust curtain working face.
• Effects of FAME Biodiesel and HVORD on Emissions from an Older Technology Diesel Engine
  12/1/2017 - Peer reviewed journal articles
  A paper comparing the potential of FAME biodiesel and HVORD as a control strategy to reduce the exposure of underground miners to aerosols and gases emitted by diesel-powered equipment.
• Simultaneously Reducing CO2 and Particulate Exposures via Fractional Recirculation of Vehicle Cabin Air
  7/1/2017 - Peer reviewed journal articles
  An article presenting research on fractional recirculation as a simple method to reduce exposures to particulate matter and CO2 in vehicles.
• Modeling Carbon Monoxide Spread in Underground Mine Fires
  5/1/2016 - Peer reviewed journal articles
