According to natural geological conditions of China, most tailings ponds constructed on the ground exist in valleys. The construction investment of the tailing pond engineering is mainly concentrated on two parts of a tailing dam body and a flood drainage system. At present, the common forms of the flood drainage system comprise a flood dam, a chute, a culvert flood discharge system, an overflow well and a tunnel flood discharge system. The purpose that the tailing storehouse set up flood discharge system has two: firstly, the rainstorm in the warehouse is eliminated in time; second, clear water in the recycling bin. In the past decades, due to the lack of a regular design and insufficient environmental awareness, flood water and tailing backwater of a flood discharge system of most tailing ponds in China are mixed and discharged in a set of flood discharge system in the actual operation process. The tailing water containing toxic and harmful chemicals such as cyanide, chloride, sulfide and the like is discharged arbitrarily, and water resources in various regions are polluted to a certain extent.
In recent years, the consequences caused by environmental protection problems are highlighted, and a plurality of environmental protection policies are correspondingly issued in China. The requirement of flood and sewage diversion is already included in the approval range of environmental protection of a tailing pond, and the tailing clarified water is required to reach the recovery rate of 100 percent. Therefore, a flood discharge system which has low investment and can realize flood and sewage diversion and thoroughly solve the environmental pollution becomes the necessary choice for mine enterprises.
Pipelines of a tailings pond conveying system in China are generally arranged on the ground or in a ditch-buried manner. The ground surface layout must cause a land acquisition problem, and the pipelines are exposed to the outside and are easy to age along with the change of climate, thereby reducing the service life.
