EVADE 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...
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.
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.
7/11/2023 - Research projectsA project to develop interventions to reduce traumatic injuries and fatalities that occur during operation and maintenance activities on conveyors.
Characterization of Forms of Silica with Varying Degrees of Crystallinity in Respirable Dust to Assess their Effects on Miners’ PneumoconiosisA contract to evaluate different forms of silica embedded in the mine-emitted dusts and how they are related to their host rocks’ mineralogical and geological features.
Investigation of Respirable Mine Dust and Crystalline Silica Dust Characteristics and Toxicity in Metal/Nonmetal MinesA contract to investigate mine dust and respirable crystalline silica characteristics and toxicity to fill a critical knowledge gap and help ensure the health of workers in metal and nonmetal mines.
A contract to provide metric analysis of dust particles collected by continuous personal dust monitor devices, which will result in useful information on dust compositions at various underground coal mines.
6/28/2023 - Contracts and cooperative agreementsA contract to explore disease pathology and help pinpoint causal respirable silica dust characteristics.
