4/1/2007 - Peer reviewed journal articlesThis 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).
-
1/1/2007 - Peer reviewed journal articlesThe 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.

10/1/2006 - Peer reviewed journal articlesIn 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.

8/1/2006 - Conference papersNIOSH 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.
-
6/1/2006 - Conference papersThe 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).
-
6/1/2006 - Conference papersThis 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.
-
6/1/2006 - Conference papersThe 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...
-
6/1/2006 - Book chaptersThis publication discusses the coal dust hazard related to explosions and how it is prevented in U.S. coal mines.
-
6/1/2006 - Conference papersThe 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...
-
6/1/2006 - Conference papersThis 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,...
