摘　　要：安太堡露天矿背斜东翼向下延深无法跟进内排,外排空间紧缺,剥离运距、高差大成为制约安全高效生产的主要问题。采用数值分析方法对斜坡内排与背斜轴以西加高排弃应力分布进行分析,结果证明:背斜影响区排弃不可行,背斜轴以西加高扩容排弃更有利于安全生产。The anticline east wing downward continuation cannot follow internal dumping,external dumping space is lack,stripping distance is large,which are the main problems of restricting the safe and efficient production.The article adopts the numerical analysis method to analyze the stress distribution of dumping in the anticline axis to west.The results show that the discarding of the anticline influence area is not feasible,and the expansion and discarding of the anticline axis to the west is more beneficial to the safety of production.
