Sampling and analysis method for measuring airborne coal

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 0.5%, 0.2%, and 0.1% for samples containing 20%, 91%, and 95% limestone dust, respectively.

Comparison of coarse coal dust sampling techniques in a

2017-5-1  The Zefon coal dust sampling cassette (ZCD, inlet size of 5.05 mm) is the industry standard for respirable coal dust sampling to meet compliance requirements (when using a size-selective cyclone on the inlet). The cassette is equipped with a 5-μm pore size PVC filter with a

Deposition Uniformity of Coal Dust on Filters and Its

Three types of 37-mm plastic sample cassettes were chosen; 3-piece, 2-piece, and the approved (MSA/Zefon) tamper-proof cassettes used for respirable dust sampling in coal mines. Using standard convention, the flow rate for the 2- and 3-piece cassettes was 1.7 lpm, and for the MSA cassettes 2.0 lpm.
