EVADE 2.0 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.
Field Investigation to Measure Airflow Velocities of a Ram Dump Car Using Circular Routing at a Midwestern Underground Coal Mine: A Case Study8/16/2019 - Peer reviewed journal articlesAn article describing a field investigation completed to determine air velocities as well as operator dust exposure during shuttle car operation.
3/20/2019 - Reports of InvestigationsWe've published an expanded second edition of NIOSH’s Dust Control Handbook for Industrial Minerals Mining and Processing.
Reducing Silica and other Respirable Hazards in the Industrial Minerals and Metal/Nonmetal Mining Industries3/6/2019 - Research projectsA project to develop control interventions to reduce occupational exposure to silica and other respirable dusts in metal/nonmetal mines and mills.
2/25/2019 - Research projectsA project to design, validate, and promote the use of advancements in monitoring the exposure of miners to respirable dust, respirable crystalline silica, and diesel particulate matter.
1/10/2019 - Contracts and cooperative agreementsA contract to develop a prototype of a next generation continuous personal dust monitor (CPDM)
