大断面锚网巷道36U复合支护技术在常村煤矿的应用

Large Section Roadway Anchor Net 36U Compound Supporting Technology Application in Changcun Mine

针对常村煤矿12220工作面上巷围岩条件和巷道变形破坏特征,运用煤巷支护技术方面的经验及工程类比法提出了巷道支护设计并应用于现场。同时对已施工巷道进行矿压观测,结果表明该支护有效的阻止了巷道围岩的变形,取得了理想的支护效果。

Based on Changcun Mine 12220 working face upper roadway surrounding conditions and roadway deformation and failure characteristics, coal roadway supporting technology experience and engineering analogy method were applied to put forward roadway support design, with application on site.Meanwhile, mining pressure observation was done to constructed roadway, the result showed that the support effectively prevented the deformation of roadway surrounding rock and the ideal supporting effect was obtained.
