针对龙都尾矿库混合式堆积尾矿坝的渗流场和稳定性开展了计算分析。结果表明，龙都尾矿库采用混合式堆坝，改善了坝体渗流场，有利坝体稳定；当坝顶标高达到＋700．0 m （堆积坝高150 m）时，尾矿坝的最小稳定系数为1．065，满足国家规范要求，采用混合式筑坝是合理可行的。
針對龍都尾礦庫混閤式堆積尾礦壩的滲流場和穩定性開展瞭計算分析。結果錶明，龍都尾礦庫採用混閤式堆壩，改善瞭壩體滲流場，有利壩體穩定；噹壩頂標高達到＋700．0 m （堆積壩高150 m）時，尾礦壩的最小穩定繫數為1．065，滿足國傢規範要求，採用混閤式築壩是閤理可行的。

The calculation analysis on the seepage field and stability for Longdu tailings damming by hybrid stac-king was conducted .The results shown that through using hybrid stacking method , the seepage field of the tail-ings dam can be improved in favor of the dam stability , and when the dam elevation reaches up +700 .0 m ( dam height 150 m ), the minimal stability factor is 1.065, which can meet the requirements of the national regula-tion.The damming by hybrid stacking method is reasonable and feasible .
