摘　　要：某矿山选矿厂配套两座尾矿库,排产规模分别为300万t/a。由于其中一座尾矿库未完成建设,需要约1年时间将全部600万t/a尾矿排入正运行尾矿库。由于排产规模扩大,现运行尾矿坝上升速率由12m/a将增加至23m/a。本文重点研究由于排产规模变大,上游式尾矿库尾矿坝上升速率超过常规时,渗流固结特性变化规律。并通过合适的排渗措施方案,使尾矿坝满足高速上升时渗流控制要求。A mine concentrator is equipped with two tailing ponds,with a capacity of 3 million t/a respectively.As one of the tailings pond has not been completed,it will take about 1 year to discharge all 6 million t/a tailings into the tailings pond in operation.Due to the expansion of the discharge scale,the rising rate of the current operating tailings dam will increase from 12m/a to 23m/a.This paper focuses on the study of seepage consolidation characteristics when the rising rate of upstream tailings dam is higher than that of conventional tailing dam due to the larger discharge scale.And through the appropriate drainage measures,the tailings dam can meet the seepage control requirements of high-speed rise.

关 键 词：上升速率 渗流固结 渗流稳定
