Ecological restoration method for tailing warehouse

Abstract

The invention provides an ecological restoration method for a tailing warehouse, and relates to the technical field of tailing warehouse restoration. The repairing method comprises the following steps; soil on the surface layer of the tailing reservoir dam face is renovated, the renovated soil is smashed evenly, a soil conditioner is added in the smashed soil, and the soil conditioner and the renovated soil are evenly mixed; the dam face of the tailing warehouse is corrected, and the surface of the renovated soil is kept flat; laying pollution-free soil on the surface of the leveled tailing reservoir to form a planting soil layer, wherein the thickness of the planting soil layer is far smaller than that of a renovated soil layer on the surface layer of the renovated tailing reservoir; plant seedlings which grow robustly and are free of plant diseases and insect pests, developed in root system and free of mechanical damage are selected, the selected plant seedlings are planted on the planting soil layer, a plurality of planting seedlings are evenly distributed on the planting soil layer, and irrigation and fertilization are conducted on the planted plant seedlings; and regularly carrying out maintenance management on the planted seedlings. According to the method, the ecological environment of the tailing warehouse can be rapidly improved.

Description

technical field [0001] The invention relates to the technical field of tailings silo restoration, in particular to a method for ecological restoration of tailings silo. Background technique [0002] A tailings pond is a place composed of dams to intercept valley mouths or enclosures and used to store metal or non-metal mines for ore sorting and discharge tailings or other industrial waste. The tailings pond is a dangerous source of artificial debris flow with high potential energy, and there is a danger of dam failure. Once it crashes, it is easy to cause serious accidents. [0003] As a type of mining wasteland, tailings wasteland not only occupies a large amount of land, but also damages a large area of ​​vegetation and landscape, resulting in the disappearance of a large number of species, a sharp decline in biodiversity and ecosystem degradation. In addition, tailings contain a large amount of toxic and harmful substances, such as heavy metals, which are easy to pollute...

AI Technical Summary

Problems solved by technology

[0004] In the tailing dam of the mining area, through artificial reclamation and ecological reconstruction, traditional artificial reclamation and guest soil are used to transform the surface soil, which is time-consuming and labor-intensive, and the cost is extremely high. However, direct planting is difficult to survive and the cost of post-planting management is high. The investment in ecological restoration of the tailing dam in the mining area remains high, which seriously restricts the process of artificially promoting the ecological restoration project of the tailing dam in the mining area
