深部巷道围岩锚网耦合支护技术

Anchor Network Coupling Support Technology in Deep Roadway Wall Rock

摘要: 通过介绍巷道围岩与锚网索耦合支护技术，得到在深部复合顶板煤层巷道实现耦合支护的基本特征在于巷道围岩与支护体在变形量、强度、刚度及结构上的耦合。通过在平煤十矿戊₉-21210风巷施工200 m的监测结果发现，巷道实施围岩与锚网耦合支护方式后，巷道顶板、两帮和底鼓均属于正常变形量，实现了一次成巷。

Abstract: Through introducing the wall rock and anchor network coupling support technology, the basic characteristics of achieving coupling support in deep compound roof seam is rest with the coupling of deflection, intensity, rigidity and structure. According to the monitoring results of 200 m at Wu₉-21210 airway in No.10 coal mine of Pingmei Shares which uses the wall rock and anchor network coupling support technology,roof of roadway,both sides and floor heave are normal. These makes roadway for a time into a lane.
