摘要:
基于赵家坝煤矿3964巷道围岩稳定性控制,采用地质雷达现场探测和理论分析结合的手段确定了巷道围岩的松动圈范围,并对多次重复采动条件下急倾斜煤层软岩巷道围岩失稳破坏机理进行分析。结果表明:复杂的地质力学环境、重复采动影响和支护方式及参数不合理是造成巷道呈“底板隆起,顶板下挫”相互错动的非对称性变形破坏的主要原因。在此基础上,提出了以高强高预应力扭矩应力锚杆、高强度让压均压锚索为基础的非对称性多介质结构耦合支护对策,并在生产实践中取得了良好的技术经济效益。
Abstract:
For the surrounding rock stability control of roadway of the No.3964 working face at Zhaojiaba coal mine,the broken rock zone of roadway are determined by geological radar detection and elasticity mechanics theory,and the mechanism of deformation and failure of surrounding rock are studied in steep coal seam during repeat mining.The results show that the asymmetric mutual rupture deformation characteristics with “bottom uplift,roof decline”is caused by complex geological and mechanical conditions,repeat mining influence,the unreasonable support design,the irrational support parameters etc.The asymmetric multi-media structure coupling support technology with high-strength yielding anchor bolt and anchor is proposed to control the surrounding rock stability,and good technical and economic benefits have been obtained.
