| 摘 要： | 王村煤矿属于"三软"复合顶板,巷道支护是一个长久探索的课题。为了解决这一问题,在13503工作面进行高强高预应力让均压锚网支护实验,并采用FLAC2D软件数值模拟优化让压均压支护系统,实践表明该支护系统能有效控制"三软"复合顶板巷道围岩变形问题,确实提高支护质量。该技术对解决本矿及类似地质条件的矿井巷道支护难题有重要的指导和借鉴意义。

| Abstract: | Wangcun coal mine belongs to the ＂three soft＂ compound roof, Its roadway support is a serious problem that should be permanently explored. In order to solve this problem, we conduct an experiment with high strength and high prestress that yielding pressure anchor nets supporting on 13503 working face, optimize yielding voltage-sharing supporting system, so as to solve the problems such as validation control the deformation of roadway wall rock, improve the quality of the support. |
