Abstract
This article discusses methods of improving airborne capture by conventional dust suppression systems. The work was performed in a full-scale plywood model of a mine entry with a wooden mockup of a Joy 12 CM continuous miner. Dust was introduced at the front of the entry, and water sprays knocked down part of the dust cloud. Sampling in the return air determined the percentage dust reduction. Based on the results, guidelines are offered for continuous miner spray systems to control dust. Empirical relations have been developed to determine the effect of changes in water spray pressure on air movement, dust knockdown, and pollutant concentrations in the face return. Nozzle selection and arrangement are discussed for high dust knockdown efficiencies.
