6/12/2023 - PC software, Reports of InvestigationsEVADE 2.4 has been updated with expanded video and data features to make it a more generalized and powerful tool.
-
2/1/2012 - Peer reviewed journal articlesThe 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.
-
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...

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.
-
9/1/2009 - 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.
-
1/1/2008 - 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.
-
2/1/2007 - 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.
-
9/1/2006 - Reports of InvestigationsThis 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.
-
8/1/2006 - 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.
-
5/1/2006 - 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.
