摘要： 针对安太堡露天煤矿南寺沟排土场的增高扩容问题，分析了影响该排土场稳定性的主要因素及可能的滑坡模式，介绍了排土参数的优化方法及工作程序。通过优化分析，使南寺沟排土场最小工作平盘宽度由65m缩小至60m，总体边坡角由17°增大至19°，增加排土容量约5000万m3，在保证露天矿生产安全、增加排土场容量、缓解排土压力等方面具有借鉴意义。

Abstract: Aiming at higher capacity problem of Nansigou waste dump in Antaibao open-pit coal mine，Combined with the actual situation，the main factors which influence the stability and the landslide model of this dump were analyzed，drainage rock parameters optimization method and work procedures were introduced.At last.Through the optimization analysis,the minimum working flat width narrowed from 65 m to 60 m, the overall slope Angle increased by 17 ° to 19 °,and the displacement capacity increased by 50 million m3.the practical significance of this method in ensuring the safety of production、increasing the dump capacity and alleviating the dump pressure,etc. were instructed.
