扎哈淖尔露天矿南帮横采内排边坡形态的确定

Determination of south slope cross mining internal dumping slope shape in Zhahanao'er Open-pit Mine

针对扎哈淖尔露天矿南帮受到顺倾地层和岩体力学性质差的影响[1-3],对初设纵采南帮到界边坡进行稳定性分析,通过建立边坡三维模型分析横采内排条件下边坡开挖位置、开挖角、追踪距离对边坡稳定性的影响,确定了横采内排条件下满足稳定性要求的南帮边坡形态。

Aiming at the effect of layered dip rocky and poor rock mechanics in south slope of Zhahanao＇er Open-pit Mine, the article carries out stability analysis on longitudinal mining to the south slope. Through the establishment of slope 3D model, the article analyzes the effect of slope excavation position, excavation angle and tracking distance to the slope stability under the condition of cross mining internal dumping, determines the south slope shape satisfying stability requirement under the condition of cross mining internal dumping.
