尾矿库排洪系统水力计算研究

尾矿库的排洪系统具有进水口多,水流流态复杂等特点,其水流形态与常见的水利工程泄水建筑物过流有较大的差别.本文采用传统的水力学方法对某工程尾矿库的排洪系统的泄洪能力进行计算,确定尾矿库的水位与下泄流量关系曲线,然后根据水量平衡方程进行调洪演算,确定排洪系统所需的调洪库容和调洪水位,从而为尾矿排洪系统设计提供可靠的依据.

Hydraulic calculation of drainage system of tailing ponds

Tailing pond drainage system has characteristics of many infalls,complicated current form which has greater difference from the familiar water conservancy discharge constructions ,and so on. The text adopts traditional hydraulics method to calculate the flood discharge capacity of certain tailing pond drainage system, fix on the relationship curve between the water level of the tailing pond and the discharge, then process reservoir flood routing according to the water-balance equation, at last choose the appropriate flood regulating capacity and level which drainage system needs. All the above provide dependable basis for the design of tailing pond drainage system..
