Abstract: Fibrous-type dust filters are used in the mining industry to capture dust particles from the active mining faces. They are used in the flooded-bed dust scrubbers to clean dust-laden air. However, the fibrous filters get clogged rapidly due to dust accumulation. Enhanced resistance due to clogging lowers the airflow rate through the scrubber and elevates the miners’ exposure. A general-purpose impingement-type dust filter was developed based on the particle impaction principle. Computer models, laboratory testing, and field experiments established its particle cleaning efficacies. The non-clogging nature of the filter allows it to operate for long periods with minimal maintenance.
