• Controlling Dust Exposures in Longwall Mining Utilizing A Simple Barrier
  12/1/2009 - Peer reviewed journal articles
  This investigation tested the feasibility of enhancing existing engineering dust controls by mounting a simple barrier on a longwall shearer that separated the operators from the cutting drums.
• Controlling and Monitoring Diesel Emissions in Underground Mines in the United States
  11/1/2009 - Conference papers
  The Pittsburgh Research Laboratory (PRL) of NIOSH conducts research to evaluate control technologies and monitoring instrumentation that can be used to reduce the diesel particulate matter (DPM) exposure of mine workers.
• Real-Time DPM Ambient Monitoring in Underground Mines
  11/1/2009 - Conference papers
  The paper discusses how the Diesel Particulate Matter (DPM) monitors have performed within the underground mine environment in evaluating DPM during the various phases of longwall moves.
• How Does Limestone Rock Dust Prevent Coal Dust Explosions in Coal Mines?
  9/1/2009 - Peer reviewed journal articles
  This study investigates how limestone rock dust prevents the propagation of coal dust explosions by assessing its changes in chemical composition.
• Observations of Post-Explosion Dust Samples From an Experimental Mine
  5/1/2009 - Conference papers
  This study shows a very good agreement between observations of partially burnt coal particles under a scanning electron microscopy (SEM) and floor dust samples, collected and analyzed using the alcohol coking test and SEM, to estimate flame travel.
• Field Evaluation of a Passive Diesel Particulate Filter at a Limestone Mine
  4/1/2009 - Peer reviewed journal articles
  In this study, the operators of a limestone mine retrofitted a loader used for clean-up operations with a passive DPF that was lightly catalyzed and used a fuel additive to initiate regeneration at low exhaust temperatures.
• Identifying Sources of Respirable Quartz and Silica Dust in Underground Coal Mines in Southern West Virginia, Western Virginia, and Eastern Kentucky
  4/1/2009 - Peer reviewed journal articles
  This paper discusses the geochemical analyses which were applied in an effort to identify the specific source rock of respirable quartz dust in coal mines.
• Workplace Solutions: Reducing Hazardous Dust in Enclosed Operator Cabs During Construction
  4/1/2009 - NIOSH/USBM numbered publications
  NIOSH found that equipment operator exposure could be reduced by retrofitting air pressurization and filtration systems on existing cabs, using sweeping compounds on soiled floors, and implementing a dust control program.
• Reducing Dust Inside Enclosed Cabs
  3/1/2009 - Videos and multimedia
  This video identifies significant factors that determine how effective an enclosed cab will be at protecting a worker.
• Diesel Exhaust Particulate Material Expression of in Vitro Genotoxic Activities When Dispersed Into a Phospholipid Component of Lung Surfactant
  3/1/2009 - Conference papers
  The study objective was to compare some in vitro genotoxic activities between solvent-extraction and surfactant-dispersion preparations for a generally available diesel exhaust reference material, U.S. National Institute for Standards and Technology DPM...
