• Respirable Quartz Hazard Associated with Coal Mine Roof Bolter Dust
  6/1/2010 - Conference papers
  This study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
• 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.
• Effects of Sampling Artifacts on Occupational Samples of Diesel Particulate Matter
  7/1/2008 - Peer reviewed journal articles
  In this study, NIOSH investigated the effects of adsorption artifact on diesel particulate matter samples from occupational settings.
• Portable XRF Analysis of Occupational Air Filter Samples from Different Workplaces Using Different Samplers: Final Results, Summary and Conclusions
  11/1/2007 - Peer reviewed journal articles
  This paper concludes a five-year program on research into the use of a portable X-ray fluorescence (XRF) analyzer for analyzing lead in air sampling filters from different industrial environments, including mining, manufacturing and recycling.
• 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.
• Current Dust Control Practices on U.S. Longwalls
  6/1/2007 - Conference papers
  Results from underground dust surveys to identify current operating practices and the types of controls being used at longwall operations are presented as an update on longwall dust control technology and operating practices.
• 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.
• Evaluation of the SKC, Inc. Dust Detective
  6/1/2006 - Conference papers
  The relationship of dust concentrations measured by personal gravimetric samplers to those measured by the SKCDD, an affordable, person-wearable, real-time dust monitor. 
• Instrumentation for Diesel Particulate Matter Emissions Research
  6/1/2006 - Conference papers
  The results of a series of tests in an underground mine were used to evaluate several measurement methods that are currently used to characterize particulate matter emitted by diesel-powered equipment. This paper presents an overview of these techniques...
