Control of the dust produced by continuous mining machines in coal mines is generally obtained by water sprays from fixed nozzles mounted on the frame of the machine in back of the cutting head. Mounting the nozzles on the rotating head of the machine closer to the coal cutting bits may improve the efficiency of dust suppression. In this study (Contract No. 0232061) to test the concept, respirable dust measurements were made during 39 regular production shifts in an underground mine using a Joy 11 cm continuous miner. The equipment used, difficulties encountered, and measurements obtained are described.
