中文摘要：

以安太堡露天矿排土场为例,采用基底承载力分析与极限平衡分析相结合的方法,研究了背斜构造影响下增高扩容方案的可行性。通过优化分析,排土场一般平盘宽度进一步缩小至65m,总体边坡角进一步增大至17°,剩余排土空间增加至33480万m~3,有效缓解了安太堡矿过背斜期间内排不能及时跟进、排土空间严重不足等问题,保证了超前剥离工作的正常进行,研究方法与成果可供借鉴。

英文摘要：

Taking a waste dump of Antaibao Open-Pit Coal Mine as a case,the feasibility was analyzed for capacity increase and heightening of the dump under anticline structure,using basal bearing capacity analysis and limit equilibrium analysis. Through the optimization analysis,the generally flat width narrowed to 65 m,the overall slope angle increased to17°and the residual displacement space increased to 334. 8 million m~3. The optimization could effectively alleviate the problems of waste dump deficiency and insufficient dumping space,ensure the normal proceeding of advance stripping.
