摘要
以祁东煤矿南部采区集中运输上山为研究对象,通过对巷道各段围岩变形进行监测,结合巷道所处的工程地质条件,初步确定DF8断层是巷道破坏的主要原因;并对巷道破坏的影响因素进行详细分析,提出了巷道修复的支护方案,现场施工取得较好效果,巷道围岩变形得到了有效控制。
In this paper, taking concentrated transportation uphill as the research object, through monitoring the deformation of surrounding rock in every section of roadway, combined with the engineering geological conditions of the roadway, it was preliminarily determined that DF8 fault is the main reason for the failure of roadway, the influencing factors of roadway damage were also analyzed in detail, relevant roadway supporting scheme was also proposed in this paper.Good effect has been achieved in field construction, and the deformation of surrounding rock of roadway has been effectively controlled.
