| 摘 要： | 为了确保巷道合理支护,对工作面回采前后锚固性能进行了测试,并进行了锚固性能对比分析,对原有巷道断面支护参数进行了优化,煤巷顶板支护采用锚网索支护,帮部采用锚网支护;岩巷采用锚网索支护,直墙采用锚网支护。研究为类似工程条件下巷道支护提供了借鉴。

| Abstract: | In order to ensure the reasonable supporting of roadway,the anchoring performance before and after mining was tested,and the anchoring performance was compared and analyzed.The original roadway cross-section supporting parameters were optimized.The roof supporting of coal drift was supported by bolt mesh cable,the sides were supported by bolt mesh;the rock drift was supported by bolt mesh cable,and the vertical wall was supported by bolt mesh supporting.The research provided a reference for roadway supporting under similar engineering conditions. |
