Through modeling analysis,theoreticalresearchandthesummaryofpracticalexperiences,thecalculationexpressionoroptimalmatching range of thefour parameters. Four parameters were applied for the optimization of the spraying dust-removal system in 20106 fully mechanized caving face in Wangjialing Mine, and the application results showed that the dust removal efficiency respectively reached97.18% and96.08% a
