CDC Mining Coarse Coal Dust Sampling NIOSH

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 IOM-MOD may improve airborne coarse dust assessments over “off-the-shelf” sampling cassettes.

Components for the analysis of dust sampling cassettes

2020-3-26  There are 8 available parts in this model: one cradle for a 4-piece-cassette, one filter holder composed of three parts to be used for the coal dust sampling cassette, and four stands for four different FTIR analyzers. The cradle and the filter holder can be used with each stand.

Standard, Mini, and Micro Cassettes for Dust Sampling

The most common design of an air sampling cassette (further “cassette”) is a 37mm cassette. They are considered to be the industry standard and are listed in multiple NIOSH and OSHA standards. The cassettes are best suitable for compliance testing where the hygienist must follow the precise instructions of a standard method. 25mm cassette

Sampling and analysis method for measuring airborne coal

2018-6-13  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.

When assessing dust hazard mitigation strategies for airborne dust reduction, sampling is done in high-velocity ventilation air, which is used to purge the mining face and gallery tunnel. In this environment, the sampler inlet velocity should be matched to the air
