7/1/2008 - Conference papersIssues related to testing the performance of sound restoration hearing protectors are outlined within this paper, and possible solutions are discussed.
6/1/2008 - Conference papersThis paper describes a portable device developed by NIOSH for measuring levels of elemental carbon in real time.
6/1/2008 - Peer reviewed journal articlesThis paper describes the 3D velocity tomograms that were generated to image the stress redistribution around an underground coal longwall panel to produce a better understanding of the mechanisms that lead to ground failure, especially rockbursts.
Analysis of Seismic Signatures from Gas and Dust Based Explosions at the Lake Lynn Experimental Mine2/1/2008 - Conference papersA seismic monitoring system at NIOSH's Lake Lynn Experimental Mine has monitored gas and dust-based explosions and impact tests. Results suggest that large unrestricted explosions can generate the same magnitude as small restricted explosions.
2/1/2008 - Information CircularsThis report summarizes a field study by NIOSH that documented the reactions of 30 miners at 4 underground coal mines concerning the use of personal dust monitors (PDMs) and how they make use of the information it provides.
Using Laser Absorption Techniques to Monitor Diesel Particulate Matter Exposure in Underground Stone Mines10/1/2007 - Conference papersThis paper describes research into a laser absorption technique that enables one to measure elemental carbon concentration in diesel particulate matter in near real time.
9/1/2007 - Peer reviewed journal articlesThis NIOSH paper documents coal miners’ reactions to the new Personal Dust Monitor (PDM), and how they make use of the information th PDM provides.
8/1/2007 - Peer reviewed journal articlesThis 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.
7/1/2007 - Conference papersThis paper describes a project in which three-dimensional time-lapse velocity tomograms were generated to image stress redistribution around a longwall panel to produce a better understanding of the mechanisms that lead to ground failure.
6/1/2007 - Conference papersThis paper presents an overview of ongoing studies, a progress report of results, and the implications for reducing worker noise exposures and preventing noise-induced hearing loss in longwall mining workers.
