摘　　要：文中对闭库尾矿库的排洪系统整治方式进行归纳总结,并以河南省头道沟赤泥库为例,阐述了最常见的新建溢洪道式排洪的整治方法,通过洪水计算、泄流能力计算、消能防冲计算,对排洪设施的安全性进行论证。结果表明,溢洪道式排洪系统可以保证尾矿库闭库后的防洪安全,研究可为今后的尾矿库排洪系统整治提供参考借鉴。This paper summarizes the remediation methods of the flood discharge system of the closed tailings pond,and takes the Chini Reservoir of Tongdaogou in Henan Province as an example to expound the most common remediation methods of the newly built spillway flood discharge.Through flood calculation,discharge capacity calculation,energy dissipation calculation and antiimpact calculation,the safety of flood discharge facilities is demonstrated.The results show that the spillway drainage system can guarantee the flood control safety after the closure of tailings pond.The research can provide reference for the future regulation of tailings pond flood drainage system.
