2/1/2010 - Peer reviewed journal articlesThe results of this study provide more insight into potential advantages and disadvantages of using biodiesel fuels for controlling emissions of aerosols and gases. Using diesel oxidation catalysts to control biodiesel emissions was re-examined.
Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine Air9/1/2009 - Peer reviewed journal articlesThis paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
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.
Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 20048/1/2006 - Reports of InvestigationsThis study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 20035/1/2006 - Reports of InvestigationsAn underground metal mine study assessed the effects of diesel emissions control technologies (such as DPF systems, diesel oxidation catalytic converter, and biodiesel blends) on concentrations of diesel particulate matter and gases in mine air.
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.
4/2/2020 - Research projectsA project to develop and implement workplace solutions to reduce miners’ overexposure to hazardous airborne contaminants emitted from diesel-powered equipment.
DPM Research: Monitoring Responses to Ventilation and Control by Water Sprays, and Capacity Building for Mine Ventilation Expertise2/5/2020 - Contracts and cooperative agreementsA capacity-building contract focused on the use of ventilation in controlling diesel particulate matter (DPM) levels, particularly in the context of challenging mining conditions.
Design, Testing, and Modeling of Environmental Enclosures for Controlling Worker Exposure to Airborne Contaminants6/1/2018 - Information CircularsRead the latest NIOSH design guidelines for environmental enclosures to reduce contaminant exposure.
2/26/2018 - Research projectsA project to investigate the feasibility of using alternative measurement approaches to quantify both elemental carbon and organic carbon in filter samples of mine air.
