Application of High Pressure Spray and Dust Reduction with Wetting Agent in Fully Mechanized Heading Face of Outburst Coal Seam
摘要
Abstract
In order to deal with the problems of high dust concentration in mine,unusable dust removal fan and the difficulties in controlling mine dust for fully mechanized heading face in outburst coal seam,this paper carried out relative research on the dust control technology of high-pressure spraying with wetting agent by choosing the fully mechanized heading face in the F15-20130 air way of Pingdingshan No.8 Coal Mine as the study object.This paper analyzed the mechanism of high-pressure spraying dust reduction.Then the composition and working principle of high pressure spray system with wetting agent were introduced.In addition,filed application was also carried out in F15-20130 air way.The results show that high-pressure spraying with wetting agent can improve the average dust suppression efficiency for mine dust by 20％ and 10％ respectively compared to low pressure spray and ordinary high-pressure spray technology.关键词
