摘　　要：介绍湖南某金矿尾矿库采用中线式废石筑坝法扩容的设计实例。采用瑞典圆弧法计算分析现状与设计最终堆积标高工况下的坝体稳定性,采用图解试算法、径流分配系数法、水量平衡法及水力计算公式计算分析现状与设计最终堆积标高工况下的防洪安全性。分析表明,该尾矿库采用中线式废石筑坝法扩容至+296.5 m标高可行,扩容后的尾矿库安全储备大,安全性提升。The design of one-step constructed tailings pond of a gold mine in Hunan with centerline embankment method by waste rock is introduced. The stability of the dam of the present situation and the design accumulation elevation is calculated and analyzed by Sweden arc method. The flood control safety of the present situation and the design accumulation elevation is calculated and analyzed by graphic algorithm trying,distribution of runoff coefficient method,water balance method and hydraulic calculation formula. It is showed by analysis results that the expansion of the tailings pond to ＋ 296. 5 m elevation with waste rock by using the centerline embankment method is feasible,the tailings safety reserve capacity and the tailings pond security are increased after the expansion.
