摘　　要：对常规平地型干式堆存尾矿库的排洪系统进行了分析,认为平地型防渗干式堆存尾矿库传统的排洪系统存在HDPE土工膜与混凝土结构连接不牢固、排水管易断裂坍塌等问题。为解决这些问题,提出了一种创新的平地型防渗干式堆存尾矿库排洪系统设置方式,通过引入透水堆石坝段和污水溢流管,使尾矿库防渗结构层保持完整,降低了污染扩散的风险,提高了尾矿库的防洪安全稳定性能。The flood drainage system of a conventional flat dry-stacked tailings pond is analyzed,and it is concluded that the system has problems such as HDPE geomembrane is not firmly connected to the concrete structure,and the drainage pipe is prone to fracture and collapse.In order to solve these problems,an innovative design of flood drainage system for flat impermeable dry-stacked tailings pond is proposed,which keeps the impermeable structural layer of tailings pond intact through the introduction of permeable rockfill dam and overflow pipe,reduces the risk of pollution diffusion,and improves the stable performance of the tailings pond in terms of flood protection and safety.
