以建新煤矿1115高位巷＂一巷两用＂的应用实践为背景,总结＂一巷两用＂在实际应用过程中存在的弊端。实践证明,采用高位巷及下向穿层钻孔条带预抽技术,虽然可以消除煤巷掘进时的突出危险性,但开采下一工作面时由于受压力影响,高抽巷与上一工作面采空区之间煤墙会产生裂隙将两者导通,给防止煤体自燃带来较大隐患。
以建新煤礦1115高位巷＂一巷兩用＂的應用實踐為揹景,總結＂一巷兩用＂在實際應用過程中存在的弊耑。實踐證明,採用高位巷及下嚮穿層鑽孔條帶預抽技術,雖然可以消除煤巷掘進時的突齣危險性,但開採下一工作麵時由于受壓力影響,高抽巷與上一工作麵採空區之間煤牆會產生裂隙將兩者導通,給防止煤體自燃帶來較大隱患。

Based on the application of ＂One Road Two Usage＂ of 1115 Elevated Lane in Jiangxin Colliery,the paper has summarized and analyzed the existing disadvantages of ＂One Road Two Usage＂ in practical application.Practice proves that using elevated lane and downward wear layer drilling strip beforehand drainage techniques can eliminate outburst danger in heading excavation,but while mining on the next face,the fissure between the coal walls of high level suction roadway and the goaf of last face will conduct both because of pressure,which brings hidden danger to coal spontaneous combustion prevention.
