• Miners' Views about Personal Dust Monitors
  9/1/2007 - Peer reviewed journal articles
  This NIOSH paper documents coal miners’ reactions to the new Personal Dust Monitor (PDM), and how they make use of the information th PDM provides.
• Dust Control Practices for Underground Coal Mining
  9/1/2007 - Conference papers
  This paper summarizes existing dust control technologies routinely being used in underground coal mine operations, and provides a review of new controls that are being pursued.
• Water Separator Shows Potential for Reducing Respirable Dust Generated on Small-Diameter Rotary Blasthole Drills
  9/1/2007 - Peer reviewed journal articles
  Tests have been conducted by NIOSH on a newly designed device for smaller diameter drills that separates the water from the bailing air before it reaches the bit and thus provides the cost benefit of dry drilling while providing the benefit of wet drill...
• Determining the Spatial Variability of Personal Sampler Inlet Locations
  8/1/2007 - Peer reviewed journal articles
  This article examines the spatial variability of dust concentrations within a coal miner’s breathing zone and the impact of sampling location at the cap lamp, nose, and lapel.
• Coal Dust Particle Size Survey of US Mines
  7/1/2007 - Peer reviewed journal articles
  Results indicate that particle sizes of mine coal dust in intake airways are finer and would require more incombustible matter to be effectively inerted than the 65% incombustible specified in current regulations.
• Explosion Temperatures and Pressures of Metals and Other Elemental Dust Clouds
  7/1/2007 - Peer reviewed journal articles
  NIOSH's Pittsburgh Research Laboratory conducted a study of the explosibility of various metals and elemental dusts, focusing on explosion temperatures. The data will aid in evaluating explosion hazards in the minerals/metals processing industries.
• Post-Explosion Observation of Experimental Mine and Laboratory Coal Dust Explosions
  7/1/2007 - Peer reviewed journal articles
  NIOSH's Pittsburgh Research Laboratory (PRL) and the Mine Safety and Health Administration (MSHA) conducted joint research on post-explosion dust samples. The data will aid in future forensic investigations of accidental coal mine dust explosions.
• Improving Silica Dust Controls for Metal/Nonmetal Mining Operations in the United States
  4/1/2007 - Conference papers
  NIOSH researchers are improving protection provided by enclosed cabs on mining equipment, reducing dust generation from surface drills, reducing dust levels in iron ore operations, and developing a new method to clean dust from soiled clothes.
• Reducing Respirable Dust Exposure of Workers Using an Improved Clothes Cleaning Process
  4/1/2007 - Peer reviewed journal articles
  A quick, safe, and effective method has been developed that allows workers to clean their dust laden work clothing periodically throughout the day.
• Performance of a Light Scattering Dust Monitor at Various Air Velocities: Results of Sampling in the Active Versus the Passive Mode
  1/1/2007 - Peer reviewed journal articles
  The Thermo personal DataRam (pDR) is an instantaneous sampler that uses light-scattering technology to provide relative measures of airborne respirable dust. The pDR can be used in active and passive modes to measure respirable dust levels.
