Control of dust produced by a longwall mining machine is generally accomplished by use of fixed sprays mounted on the machine housing and by sprays mounted on the drum but not directed at the cutting bits. Mounting nozzles on the drum so that each bit is flushed by a jet of water may improve the efficiency of dust suppression. To test this concept, respirable dust measurements were made during 94 regular production shifts on a longwall section, using an eickhoff model ew-170-l ranging drum shearer. The equipment used, difficulties encountered, and measurements obtained are described.
