摘要
为了解决巷道底鼓变形严重的问题,以薛虎沟矿10102工作面为工程背景,采用数值模拟软件对原有支护及无支护条件下巷道围岩情况进行分析,给出原有支护方案的不足,提出锚网索+底锚的支护方案对巷道底鼓进行控制,有效控制了巷道底鼓变形,为日后巷道支护提供参考。
In order to solve the problem of serious floor heave deformation,taking the 10102 working face of Xuehugou Coal Mine as the engineering background,this paper used the numerical simulation software to analyze the surrounding rock of the roadway under the conditions of the original support and no support,gave the shortcomings of the original support scheme,put forward the support scheme of anchor mesh cable+bottom anchor to control the floor heave of the roadway,effectively controlled the floor heave deformation of the roadway,and provided reference for the support of the roadway.
