摘要
在查明会东矿露天西边坡的工程地质条件及地质构造的基础上分析了影响边坡稳定性的各种因素,用地质力学方法对西边坡的整体稳定性进行了评价。认为,由于“地堑式”断块形成的岩体断陷以及寨武系岩层中的构造作用形成的黑色破碎带,其特性软弱而易变形,是影响边坡稳定性的重要因素。因而,为确定合理的最终边坡角和安全生产及边坡维护提供了可靠依据。
On the basis of knowing the engineering geologic conditions and geologic structures through investigation, the influence factors on the slope stability were analyzed and, with the geomechanics method, the west-slope integral stability at the mine is also evaluated.The authors consider that the rock fault depression, formed by the graben fault block, and the black fracture zone, formed from the structure action of the Cambrian system formation, are characterized by weakness and easy deformation, which are the important factors to influence the slope stability.Thus, this study has provided strong assurance for the determination of final pit slope angle, slope protection and safety production.
