摘要
旗山矿-1000m水平北翼联络轨道大巷在初期掘进过程中,在断层附近巷道顶板上方出现了一定规模的冒落带。通过对巷道工程地质条件的分析和围岩特性的研究,确定了巷道围岩的类型及其变形力学机制,提出了巷道修复支护技术,在现场应用取得了成功。
During the initial excavation process of the north connection rail line roadway at - 1000 m level of Qishan Mine, a certain large roof falling zone occurred in the roof of the mine roadway with a fault. With the analysis on the engineering geological conditions of the mine roadway and the research on the surrounding rock features, the type of the roadway surrounding rock and the deformation mechanics mechanism were set up. The paper provided the repair and support technology of the mien roadway and the site application of the technology obtained the successful results.
