| 摘 要： | 露天矿边帮巷道的变形破坏与边坡稳定性、巷道的空间位置和围岩性质等因素直接相关.针对鞍钢集团大孤山露天铁矿边帮巷道衬砌开裂的现象,利用地质雷达对裂缝开裂处的巷道围岩进行了破坏深度的探测,获得了巷道衬砌裂缝开裂处围岩破坏程度.分析了巷道的空间位置和边坡稳定性对巷道变形破坏的影响程度.结果表明:大孤山露天铁矿巷道衬砌开裂的机理主要是巷道围岩病害所致,而非整体边坡的滑动所致,为巷道的治理提供了科学依据. |

| Abstract: | The deformation and failure of the slope tunnel is directly related to the slope stability,the spatial location of the tunnel,and the mechanical parameters of surrounding rock mass.Based on the cracks of the transportation tunnel in Dagushan Iron Mine,the failure depth of cracks in the surrounding rock mass was measured by geological radar in this paper.The failure level of the surrounding rock mass in every crack is obtained,and the spatial location of the tunnel and slope stability on the influence of def... |
