摘要
主要研究了元宝山露天煤矿内排土场的工程地质特征,分析了内排土场滑坡的破坏模式,确定了满足河流通过的内排土场稳定系数,利用刚体极限平衡法对不同排弃平盘宽度的内排土场稳定性进行分析,确定了最优排弃平盘宽度为55 m。
The article studies the engineering geological characteristics of inner dump in Yuanbaoshan Open-pit Coal Mine,analyzes the failure mode of dump landslide, and determines the stability coefficient of the inner dump satisfying the river pass.The author analyzes the stability of inner dump with rigid body limit equilibrium method under the different width of the berm, and determines the optimal abandoned berm width with 55 m.
