• The Fate of Metal (Fe) During Diesel Combustion: Morphology, Chemistry, and Formation Pathways of Nanoparticles
  4/1/2007 - Peer reviewed journal articles
  This report describes an investigation in which NIOSH used iron-doped diesel fuel to generate metal-bearing diesel particles and a subsequent analysis of the particles using transmission electron microscopy (TEM) and energy-dispersive spectroscopy (EDS).
• 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.
• Effects of Trace Metals on Particulate Matter Formation in a Diesel Engine: Metal Contents from Ferrocene and Lube Oil
  10/1/2006 - Peer reviewed journal articles
  In this study, the single particle mass spectrometer (SPMS) was applied to explore the composition of DPM, namely the origin of metals and size preferences of metals originating from metallic fuel additives and lube oil.
• Post-Explosion Observations of Experimental Mine and Laboratory Coal Dust Explosions
  8/1/2006 - Conference papers
  NIOSH and MSHA conducted joint research on dust explosions by studying post-explosion dust samples of high and low volatile bituminous coals collected from full-scale explosions at NIOSH's Lake Lynn Experimental Mine and from laboratory explosions.
• The Effects of Water Emulsified Fuel on Diesel Particulate Matter Concentrations in Underground Mines
  6/1/2006 - Conference papers
  The ambient diesel particulate matter (DPM) concentrations (at the intakes and exhausts of the mine) was evaluated as an entire vehicle fleet of a stone mine switched from using 35% biodiesel to a water-emulsified fuel (PuriNOx).
• Implementation of Diesel Particulate Filter Technology in Underground Metal and Nonmetal Mines
  6/1/2006 - Conference papers
  This paper provides detailed analysis of some of those challenges and short overviews of several projects launched by the NIOSH Pittsburgh Research Laboratory in an attempt to provide the underground mining industry with more adequate DPF systems.
• 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...
• Explosion Hazards of Coal Dust in the Presence of Methane
  6/1/2006 - Book chapters
  This publication discusses the coal dust hazard related to explosions and how it is prevented in U.S. coal mines.
• DEEP Project on Evaluation of Diesel Particulate Filters at Inco's Stobie Mine
  6/1/2006 - Conference papers
  The objective of the Diesel Emissions Evaluation Program (DEEP)-sponsored project at Inco Ltd.'s Stobie Mine was to conduct a long-term field evaluation of diesel particulate filter (DPF) systems available to the underground mining industry. Some of the...
• Emerging Technologies Control Respirable Dust Exposures for Continuous Mining and Roof Bolting Personnel
  6/1/2006 - Conference papers
  This paper discusses NIOSH studies evaluating the impacts of emerging technologies that may reduce dust exposures for continuous mining and roof bolting personnel. These technologies include use of a wet-head cutting drum on a continuous mining machine,...
