Analysis on Test of Windwater Spraying Dropdust of Fully Mechanized Caving Workface in ShiGeJie Coal Mine

This papee designs test of windwater spraying dropclust of 2307 fully-mechanized caving workface,evaluates effect of dropdust analyzes source and distribution of coal clust when shearer is mining discusses principle and main cause of windwater spraying dropdust,and gives a good measure;this method is very good through tentative test on-the-spot,it improves work condition of fully-mechanized caving workface,structare of this combined mechinery is rational and easy to use,pressure wine raises kinetic energy of sprayor head improves atomizing of result.It can take effect of dropping dust.
