Since isokinetic sampling is conventionally used to determine total dust concentration, and isokinetic sampling made a difference in collected masses, the results suggest when sampling for coarse coal dust the IOMMOD may improve airborne coarse dust assessments over "offtheshelf" sampling cassettes.
D. Total Dust Sampling Train . Total dust sampling uses the same type of filter cassette required for respirable dust sampling. Assemble the apparatus with Orings placed on the top and bottom of the cassette to seat the cassette snugly in the cassette holder (refer to Figure 54), or use the top of the metal cyclone holder seated into the cassette
A commercial version of the BOM impactor, called the DPM Cassette, was recently introduced by SKC[registered sign]. Tests were conducted to evaluate the performance of the DPM Cassette for measuring dieselsource elemental carbon in the presence of coal dust. Bituminous coals from three mines in two different coal provinces were examined.

Mixtures of known coal and limestone dust masses were prepared in the laboratory, loaded into the stainless steel cassettes, and analyzed to assess the accuracy of this method. Coal dust mass measurements differed from predicted values by an average of %, %, and % for samples containing 20%, 91%, and 95% limestone dust, respectively.
Each cassette is supplied with a mine data card for the weight of the filter capsule to be recorded and sent in a mailing carton addressed to MSHA. Preweighed filter cassette with 5µ pore size PVC filter and Mine Data CardCoal Dust Sampling . 803462 . GeneralPurpose Cassette . 711361
The final rule only addresses the approval of coal mine dust sampling devices. As stated previously, this rule does not address their particular use in coal mines. Therefore, the final rule does not affect coal mines, nor does it have a significant energy action that adversely affects energy supply, distribution, or .
SKC Diesel Particulate Matter Cassettes are designed for sampling in atmospheres where it is necessary to separate DPM from other respirable dust (such as coal dust). Singleuse SKC DPM Cassettes are tamperevident sealed to ensure sample integrity. Each streamlined plastic cassette comprises an impactor plate, impaction substrate, and two heat ...
Since isokinetic sampling is conventionally used to determine total dust concentration, and isokinetic sampling made a difference in collected masses, the results suggest when sampling for coarse coal dust the IOMMOD may improve airborne coarse dust assessments over "offtheshelf" sampling cassettes.
The mass fractions of the total quartz sample on the internal cassette surface are significantly different between polystyrene and staticdissipative cassettes for all cyclones (p < ). No consistent relationship between quartz mass on cassette internal surface and coal dust filter mass was observed.
About 99 percent were in compliance. These results correspond to the respirable dust samples collected from Aug. 1, 2014, through Jan. 2016, during Phase I, when 87,000 dust samples were collected from surface and underground coal mines by MSHA and coal mine operators. Nearly 99 percent of those samples met the dust concentration limit.
