全岩巷综掘面综合防尘技术及应用

为了解决全岩巷综掘面高浓度粉尘危害问题,提出了构建以降尘泡沫、除尘风机为主,以分级净化水幕、个体防护为辅的综合控(除)尘体系,并在张集矿1123(3)~1124(3)瓦斯底抽巷综掘现场进行应用,结果表明:司机处测得的总粉尘和呼吸性粉尘的降尘率分别为92.5%和96%,配合个体防护及净化水幕,有效地治理了掘进巷道粉尘危害。

The Comprehensive Dust Control Technology and Application for Fully Mechanized Excavation Face of Whole Rock Tunnel

Abstract: To solve the problem of high dust concentration hazard caused by whole rock tunnel excavation，aiming at the rock dust hazards of Zhangji coal mine working face，the paper put forward to create a combined system which gives priority to froth dedusting，dust exhausting fan，assits with the grade purified water curtain and individual protection，and put it into application at the 1123(3)~1124(3) gas drainage lane. The results show that the average dust-settling effect is 92.5% and 96% for the total dust and respirable dust. Cooperating with individual protection and the water curtain，the combined system has achieved a good effect of controlling dust.
