摘要：
摘 要：为了解决全岩巷综掘面高浓度粉尘危害问题，并针对张集矿工作面岩尘危害的现状，提出了构建以降尘泡沫、除尘风机为主，辅助分级净化水幕、个体防护的综合控、除尘体系。通过在张集矿1123（3）~1124（3）瓦斯底抽巷现场应用，结果表明：对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，有效地防治了粉尘的危害。

Abstract:
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.
Key words: whole rock tunnel, fully mechanized excavation face, dust hazards, comprehensive dust control
