| 摘 要： | 以郑兴矿为研究背景,通过实验室压缩试验和现场变形监测分析,得到了软岩巷道变形特征并验证了支护的合理性.结果表明,围岩变形具有明显的非对称、非均匀性,深部变形量逐步减小;支护初期围岩收敛较大,后期变形速率逐渐减小;"锚网索喷"联合支护能够有效控制围岩变形,保证巷道安全.

| Abstract: | Taking Zhengxing Mine as the research background,through laboratory compression test and field deformation monitoring analysis,the deformation characteristics of soft rock roadway are obtained,and the rationality of support is verified.The research results show that the deformation of soft rock show obvious asymmetry and non-uniformity.The amount of deep deformation decreases gradually,the convergence of surrounding rock in the initial stage of support is large,and the deformation rate decreases gradually in the later stage.The combined support of"Anchor net cable spray"can effectively control the deformation of surrounding rock and ensure the safety of roadway. |
