跨采巷道围岩变形分析

Deformation Analysis of Surrounding Rock in Crossing Roadway

针对某矿21盘区辅助巷道变形量大的问题,介绍巷道支护,分析现有巷道在使用过程中出现的问题以及跨采动压巷道围岩稳定性的影响因素。结合巷道围岩及矿上地质材料分析可知,巷道变形量大与巷道围岩应力大、锚杆锚索支护选择不合理及围岩遇水膨胀有关,为巷道支护优化提供参考。

In order to optimize the support of roadway and solve the problem of large deformation of roadway, this paper analyzes the present situation of roadway support, and analyzes the problems that appear in the course of using existing roadway, in order to optimize the roadway support and solve the problem of large amount of deformation of roadway. Based on the analysis of the surrounding rock and geological materials of the roadway, it can be seen that the large deformation of the roadway is related to the large stress of the surrounding rock of the roadway, the unreasonable selection of the bolting cable support and the water expansion of the surrounding rock, which provides a reference for the optimization of the roadway support.
