某铜矿尾矿库扩容方案研究

Research on Capacity Expansion Scheme of a Copper Mine Tailings Pond

某铜矿尾矿库位于高寒地区,运行过程存在冰冻层,且浸润线高。综合分析尾矿库所在区域气候、地形、周边土石料等特点,提出了具体的解决措施,如利用排土场边坡作为部分坝体,按冰冻期及非冰冻期选择不同放矿工艺,将北侧西支沟设置为库外回水调节库等,为该尾矿库加高扩容提供了一个综合解决方案,可供类似尾矿库扩容借鉴。

The subject copper mine tailings pondis located in the alpine region. Dangers during its operation, theere is frozen layer and the seepage lineis high. The paper analyzes climate, topography, surrounding soil and rock and other characteristics of the location for the tailings pond and proposes to make use of the waste disposal dump slope to form a part of the dam body, choose different tailings disposal methods in freezing and non-freezing periods, and set the west branch ditch in the north side as the backwater regulation pond outside the railings pond, so as to provide a comprehensive solution for expansion of the tailings pond and thus a reference for expansion of similar tailings ponds.
