Embodiment Construction

[0033] An ecological restoration method for reclamation of tailings ponds after the closure of the present invention, comprising: a water storage system, dredging, excavation and expansion of the catchment area of ​​the tailings ponds before transformation, sandbag slope protection, and geomembrane formation transformation The water area of ​​the rear tailings reservoir and the construction of multi-stage reservoirs for water storage, as much water as possible under the premise of controlling the length of the dry beach; the elevation of the multi-stage reservoirs should be higher than the water level of the modified tailings reservoir, The size and quantity of the pools are determined according to the irrigation needs. The water in the multi-stage reservoirs is used for irrigation, and the water is extracted from the tailings pond water area or river and well water after the transformation by the water pump. The maximum water level of the tailings pond water area after the tran...

Abstract

The invention discloses an ecological restoration method for tailing depot reclamation after tailing depot closure. According to the ecological restoration method, a water storage system, a water drainage system and an irrigation system are designed; construction restoration measures adopted by each system accord with environmentally friendly ecological restoration; an interrelated overall system can be formed through the water storage system, the water drainage system and the irrigation system; much water can be impounded in dry seasons so as to be used for irrigation, and floodwaters can be rapidly drained in flooding in rainy seasons, and therefore, the safety of a tailing depot can be ensured, and gravity irrigation can be realized; and regulation can be performed according to the needs of crops, water level in the tailing depot, and weather conditions. The ecological restoration method of the invention can be applied to reclamation ecological restoration and effective utilization of tailing depots after tailing depot closure in various kinds of mines.

Description

technical field [0001] The invention belongs to tailings ponds after mine closures. Specifically, it is an ecological restoration method for reclamation of tailings ponds after closure. It ensures the greening and ecological restoration of the tailings pond reclamation after the closure of the reservoir. Background technique [0002] At present, due to large-scale mining, a large amount of sandy soil waste is piled up in the valleys between mountains to form tailings ponds. Tailings ponds are a major source of danger. If they are not properly managed and disposed of, debris flows are likely to form under the action of storms, floods or earthquakes, causing devastating damage to downstream villages and towns. The main reason for the formation of mudslides is that the heavy rain caused the water level in the reservoir to rise, the drainage system failed, and the flood flooded the top. At present, the conventional practice is to drain the water level in the reservoir, which ...
