堆积型尾矿坝坝体颗粒级配情况因尾砂排放和堆积的形式而千变万化，因此仅仅采用海森经验公式估算其毛细水上升情况会造成很大的偏差。为此，以湖南某尾矿坝坝体尾砂为原料，采用均匀设计方案设计并配比了8种尾矿砂，随后对该8种尾矿砂中的毛细水上升情况进行了长达10个月的监测，系统地研究了颗粒级配的差异对毛细水上升过程的影响。研究表明，毛细水初期阶段上升速度与尾矿砂中粗粒颗粒含量成正比，其最终上升高度则由细粒含量所决定。进一步地，还得出了由颗粒级配估算毛细水上升高度的方法，为毛细水上升高度计算理论提供了一种新思路和新方法。

The grain composition of stacking tailings dam varies greatly with the forms of tailings discharge and heap, so only applying the Hazen formula to calculate the height of capillary water rise may cause large error .Tak-ing the tailings sand sampled from a tailings dam in Hunan Province as raw material , eight kinds of grain composi-tions are programmed by the uniform design .The processes of capillary water rise were monitored over ten months , and a systematic research was carried out to find out the influence of different grain composition on the capillary wa -ter rise.The results showed that the speed of capillary water rise is proportional to the coarse particle content in the early stage, but the final rise height is determined by the fine particles content .Furthermore, a method for estima-ting the height of capillary water in tailings dam was established .It provides a new idea and enriches the theory on calculating the rising height of capillary water .
