Float dust reductions of >90% can be achieved by adding an in-line wetted scrubber to an auxiliary section fan. Coal mine operators can use this combination to reduce the possibility of a coal dust explosion in the return.
For Spanish speakers, download the same infographic with text in Spanish.
Photo of scrubber system as installed in an underground coal mine return entry shown. The photo is taken from a perspective to represent the entire assembly. From left to right, there is a labeled wetted scrubber section, then a flexible duct that connects to the auxiliary fan that pulls air through the scrubber, then a labeled auxiliary fan. The rib and floor of the mine workings are also visible and most everything is coated in gray rock dust. There is a labeled arrow beneath the scrubber system pointing to the right to represent the airflow direction.Reference - March 2019
