摘要
泰宁某尾矿库初期坝（主坝）建于侵蚀剥蚀丘陵沟谷地形较窄处，经十年的生产运营，尾矿渣堆积厚度12-26m，库内已形成七级堆积子坝（坝高1．5-4．5m），其中第七级子坝坝高程371．0m，目前已超过设计一期堆高6．0m。本文通过对普遍存在的尾矿库堆渣坝的环境地质条件及坝址稳定性分析，主要针对地下水的影响情况进行相应的计算论证，得出地下水渗透力作用时的安全系数及其相应稳定的库岸条件机理。
Taining the beginning of a tailings dam （main dam） was built in erosion of denuded hilly terrain narrow valley Department,After 10 years of production operation, tailing piled up 12 - 26 m thickness, Register accumulation has formed seven sub -Pa （long and 1. 5 - 4.5m）, with the seventh - grade Dam Dam - 371.0 m, has now exceeded design a reactor 6.0 m high. Based on the prevalence of the tailings dam slag heap environment and geological conditions dam stability analysis, mainly aimed at the impact of groundwater for the corresponding calculation verification, draw groundwater infiltration role of the safety factor and the corresponding conditions for a stable mechanism of the bank.
