Oct 01, 2014 Outcome: Laboratory testing on a longwall shearer fan-powered, flooded bed scrubber designed by the University of Kentucky's Mining Engineering Department was conducted by NIOSH at the Pittsburgh Mining Research Division (PMRD) longwall dust gallery. Results showed that the scrubber reduced respirable dust by 56% in return airways and by 74% in

Oct 01, 2019 Flooded-bed scrubbers and water sprays are used to control respirable dust in the underground environment. Both the Mine Safety and Health Administration (MSHA) and the National Institute for Occupational Safety and Health (NIOSH) have identified instances of poor dust control due to inadequate spray operation and loss of flooded-bed scrubber airflow on continuous mining machines
