This research (Contract No. H0232060) compared the dust suppression of a 120 m Jeffrey continuous mining machine using (1) water through the drum (wet head) or (2) conventional sprays. This objective was accomplished by collecting respirable dust samples at various locations of an operating mine production section. Twenty-eight valid samples were collected; eight used the conventional spray system and twenty used the wet-head technique. Statistical analysis of the data indicates that the wet-head technique reduces dust by about 10 percent over the conventional water sprays on the continuous miner.
