• EVADE Software
  6/12/2023 - PC software, Reports of Investigations
  EVADE 2.4 has been updated with expanded video and data features to make it a more generalized and powerful tool.
• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• Field Evaluation of Air-blocking Shelf for Dust Control on Blasthole Drills
  3/1/2011 - Peer reviewed journal articles
  Field 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...
• Aerosols Emitted in Underground Mine Air by Diesel Engine Fueled with Biodiesel
  2/1/2010 - Peer reviewed journal articles
  The 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 Air
  9/1/2009 - Peer reviewed journal articles
  This 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.
• Equivalency of a Personal Dust Monitor to the Current United States Coal Mine Respirable Dust Sampler
  1/1/2008 - Peer reviewed journal articles
  The 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 Mines
  2/1/2007 - Peer reviewed journal articles
  To 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.
• Laboratory and Field Performance of a Continuously Measuring Personal Respirable Dust Monitor
  9/1/2006 - Reports of Investigations
  This report includes the theory of operation, description, and the performance of the Personal Dust Monitor (PDM) compared to gravimetric-based reference dust sampling methods and laboratory verification of the instruments accuracy.
• Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 2004
  8/1/2006 - Reports of Investigations
  This 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, 2003
  5/1/2006 - Reports of Investigations
  An 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.
