9/1/2011 - Peer reviewed journal articlesResults from the NIOSH underground dust surveys and current longwall dust control technology and operating practices are discussed.
3/1/2011 - Peer reviewed journal articlesField tests confirm that an air-blocking shelf installed in the inside perimeter of a blasthole drill shroud substantially improves dust control. This modification reduced respirable dust by 66%–81% in the immediate vicinity of the shroud...
1/1/2011 - Reports of InvestigationsDust surveys determined if deep-cut mining expose face workers to higher levels of respirable dust. Study findings indicate that levels on bolting faces did not appear to be affected by longer cycles associated with deep-cut mining practices.
This handbook was developed to identify available engineering controls that can assist underground and surface metal/nonmetal mining operations in reducing worker exposure to respirable silica dust.
2/1/2010 - Conference papersThis paper describes field tests conducted by NIOSH to evaluate the effectiveness of a wet head continuous mining machine for reducing dust exposure for continuous miner operators.
This handbook was developed to identify available engineering controls that can help the industry reduce worker exposure to respirable coal and silica dust.
Equivalency of a Personal Dust Monitor to the Current United States Coal Mine Respirable Dust Sampler1/1/2008 - Peer reviewed journal articlesThe work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
Relationship Between Elemental Carbon, Total Carbon, and Diesel Particulate Matter in Several Underground Metal/nonmetal Mines2/1/2007 - Peer reviewed journal articlesTo evaluate how elemental carbon (EC), a surrogate of diesel particulate matter (DPM), predicts DPM, measurements of total carbon (TC) and EC were taken away from potential interferences in four underground metal/nonmetal mines during production.
12/1/2004 - Peer reviewed journal articlesA commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC®. Tests were conducted to evaluate the performance of the DPM Cassette for measuring diesel-source elemental carbon in the presence of coal dust.
5/10/2019 - Peer reviewed journal articlesAn article describing dust collection equivalency testing of a new PDM air inlet against the original cap-mounted inlet design.
