某沟谷型尾矿库回水系统布置方案探讨

Discussion on scheme arrangement of backwater system in a valley tailings pond

针对国内某沟谷型尾矿库地形陡峭的特点,提出了两种回水系统的布置方案,分别为浮船泵站一级回水和缆车泵站+岸坡泵站二级回水,开展了方案技术经济对比分析。研究结果表明,对于多雨地区采用水量平衡法计算回水量更符合实际,两种布置方案均可行,但采用浮船泵站一级回水,技术成熟度高,更易于管理。研究可为类似工程提供参考。

Given the steep terrain characteristics of valley tailings pond inland, two different return water systems are proposed, the one-stage return water system of floating ship pumping station and the two-stage return water system of cable car pumping station+bank slope pumping station, techno-economic comparison, comparing it′s technical and economic.Research shows that the water balance method is more suitable for the calculation of return water in rainy areas.Both schemes are feasible, however, the technology of the one-stage return water system of the floating ship pumping station is more mature and easier to manage.The research can provide a reference for similar projects.
