• 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.
• 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.
• 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.
• Effects of Hydrotreated Vegetable Oil on Emissions of Aerosols and Gases from Light-Duty and Medium-Duty Older Technology Engines
  4/1/2016 - Peer reviewed journal articles
  This article by NIOSH describes a study conducted to assess the potential of hydrotreated vegetable oil renewable diesel (HVORD) as a control strategy to reduce exposure of workers to diesel aerosols and gases.
• Quantification of Optical and Physical Properties of Combustion-Generated Carbonaceous Aerosols (less than PM2.5) Using Analytical and Microscopic Techniques
  3/1/2015 - Peer reviewed journal articles
  An article describing experiments conducted to quantify and characterize the optical and physical properties of combustion-generated aerosols during both flaming and smoldering combustion of three materials common to underground mines.
• Aerosols and Criteria Gases in an Underground Mine That Uses FAME Biodiesel Blends
  10/1/2014 - Peer reviewed journal articles
  A study assessing heavy-duty haulage trucks' contribution to the concentrations of aerosols and criteria gases in underground mine air and the physical properties of those aerosols for three FAME biodiesel blends.
