上游法细颗粒尾矿高坝筑坝技术措施设计探讨

Discussion on Design of Technical Measure for High Dam Construction with Fine Grained Tailings by Upstream Method

上游法筑坝方式因为工艺简单,成本低而被我国矿山广泛采用,但是对于细粒级的尾矿而言,传统的上游法筑坝遇到了经济性和安全性相冲突的矛盾,对于高坝而言,这一矛盾更为突出。本文结合云南省某尾矿库实例,提出一些上游法细颗粒尾矿高坝筑坝技术的措施设计方法,以供探讨。

Upstream dam construction method is widely adopted by domestic mine due to simple process and low costs, but up- stream dam construction method for fine grained railings has the conflict contradictions between economy and safety, this contradiction is more outstanding to high dam. Some design methods for technical measures of high dam construction with fine grained tailings by upstream method is proposed according to a living example of a railings pond in Yunnan province.
