摘要
针对石嘴山一矿深井软岩巷道锚网喷支护中存在的问题,以岩石物理及力学特性实验为基础,现场破坏情况为依据,从地质条件、围岩性质、支护结构、施工管理等方面分析了巷道围岩变形、破坏的原因,提出了控制围岩稳定性建议,对巷道支护实践有一定的参考价值。
There are some problems on the support of shotcreting and bloting mesh for deep weak rock roadway in NO. 1 Mine of Shizuishan. Based on experiment of physical and mechanical characters and analysis of minerals composition of weak rocks, and destroy condition of roadway, analyzed the reason for deformation and failure of surrounding rocks from some aspects on arrangement of roadway, design of support, properties of surrounding rocks, management of construction and so on, and provided suggestions of controlling surrounding rocks of roadway stability, which has a certain reference value of practicing to support roadway.
