7/1/2015An article presenting an assessment of the effects that ground control mesh might have on rock and float coal dust distribution in a coal mine.
-
3/31/2015 - Contracts and cooperative agreementsA contract to develop a monitor that can measure diesel particulate matter (DPM) in real time for at least a month and provide information on the mine-wide DPM concentrations to a central control station located on the surface.
-
3/1/2015 - Peer reviewed journal articlesAn article describing an investigation of the relationship between total carbon and elemental carbon from diesel particulate matter samples to determine if a single conversion factor can be used for all metal/nonmetal mines.
-
12/1/2014 - Peer reviewed journal articlesAn article presenting a performance evaluation of a wearable, real-time DPM monitor, the Airtec, in several underground metal/nonmetal mines by comparing it to the standard method for determining DPM exposures (NIOSH method 5040).
-
10/11/2014 - Contracts and cooperative agreementsA contract to provide miners with real-time alerts to potentially harmful air contaminants if a dangerous threshold of either immediate or timed exposure is detected.
-
2/1/2014 - Peer reviewed journal articlesAn article describing the results of a field test to verify the effectiveness of MERV 16 filters in the enclosed cab filtration systems on a face drill and roof bolting mining machine, which were tested at an underground limestone mine.
-
10/1/2013 - Peer reviewed journal articlesA study to compare the effects of particles generated by engine fueled with neat biodiesel and neat petroleum-based diesel.
-
6/1/2013 - Peer reviewed journal articlesAn article evaluating a commercial instrument developed based on NIOSH research for measuring EC concentrations in real time.
-
3/1/2013 - Peer reviewed journal articlesA study of the mutagenic potential of diesel emissions from neat and blended soy-based fatty acid methyl ester (FAME) biodiesel compared to ULSD PM using different engine operating conditions and exhaust aftertreatment configurations.
-
12/1/2012 - Peer reviewed journal articlesThis study was conducted to evaluate the effects of a diesel particulate filter (DPF) regeneration process on the concentrations and size distributions of aerosols in an underground mine.
