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.
