EVADE 2.2 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.
10/5/2019 - Research projectsTo develop and evaluate technologies and approaches to improve effective dust controls to reduce respirable coal mine dust (RCMD) exposures in coal mines, focusing on reducing respirable quartz dust (RQD).
10/5/2019 - Research projectsTo demonstrate the suitability and efficiency of monitoring and control solutions which will help to lower the respirable dust exposure of M/NM miners.
10/2/2019 - Research areasThis page summarizes how NIOSH is addressing respiratory diseases in the mining industry.
