摘要
告成煤矿-110 m大巷围岩松软,巷道变形严重,通过对巷道围岩破坏机理的分析,确定了一套36U型钢+壁后注浆+结构补偿支护技术,实践表明,该技术有效解决了松软围岩巷道变形难题。
Aimed at soft 110 big roadway encircling rock and strongly deformed roadway, the authors have analyzed the destroyed mechanism of roadway encircling rock and defined a set of supporting technology with 36U-- shaped steel ＋ grout with wall back ＋ structural compensation, which has proved to solve the problem of soft encircling rock deformation.
