Respirable Dust Rule: A Historic Step Forward in MSHA

MSHA’s final rule to lower miners' exposure to respirable coal mine dust is a historic step forward in the effort to end black lung disease The rule reduces overall dust standards in coal mines, improves the dust sampling technology and methodology, and expands the medical surveillance program to improve early detection of the disease

MSHA finds nearly all respirable coal dust samplings

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

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

MSHA Implements Respirable Dust Rule | Coal Age

04/08/2014· The final rule lowers miners’ exposure to coal dust, substantially increases operator sampling for respirable coal mine dust, and requires immediate corrective action when an operator’s sample shows excessive concentrations While the frequency of sampling by MSHA inspectors does not change, the final rule authorizes MSHA to cite an operator based on a single MSHA sample showing

Comparison of coarse coal dust sampling techniques in a

ABSTRACTAirborne coal dust generated during mining can deposit and accumulate on mine surfaces, presenting a dust explosion hazard When assessing dust hazard mitigation strategies for airborne dust reduction, sampling is done in highvelocity 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
