Ecological restoration method for abandoned mine

Abstract

The invention discloses a waste mine ecological restoration method, and belongs to the technical field of ecological restoration, the waste mine ecological restoration method comprises the following steps: S1, supplementing a soil source, searching a high-quality soil source nearby, and laying the soil source on the surface of a mine in a strip manner, S2, eliminating metal toxins, preparing solutions of calcium, magnesium, selenium, zinc and the like, uniformly spraying the solutions on the soil source, and carrying out soil restoration. The method comprises the following steps: S1, carrying out fertilization at regular intervals, and frequently using nitrogen, phosphorus, potassium and other fertilizers to supplement the fertility of soil; S4, culturing plants, and culturing and planting boston ivy, commeline communis and other plants on the surface of a soil source; S5, adding animals, and releasing a plurality of groups of earthworms in the soil source; S6, covering a mulching film, and covering the surface of the soil source with the mulching film by using a laying frame; the soil activity can be improved, the mine remediation period is shortened, plant growth is promoted, meanwhile, use of redundant equipment is reduced, the remediation cost is reduced, and the life safety of workers is protected.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, and more particularly, to a method for ecological restoration of abandoned mines. Background technique [0002] At present, my country is in the period of industrialization, and mineral resources have become an important material basis for my country's economic development. However, with the development of the mining industry, the ecological environment of mines, soil matrix, soil structure, groundwater and biodiversity have all been severely damaged. Therefore, ecological restoration of abandoned mines is an important measure to optimize the ecological environment. [0003] The traditional ecological environment restoration is to first detect the mine soil and judge its internal conditions, and then use drones or other equipment to spray a special solution on a large area of ​​the abandoned mines to restore the abandoned mines to their original state as much as possible, and finall...

[0003] The traditional restoration of the ecological environment is to first detect the mine soil, judge its internal conditions, and then use drones or other equipment to spray a special solution on a large area of ​​the abandoned mine, so that the abandoned mine can be restored to its original state as much as possible, and finally by transplanting animals and plants To restore the ecological environment of the mine, but this method has a long repair period, and uses more equipment and a large amount of work, which leads to continuous increase in repair costs. If you do not pay long-term attention to it, it is easy to make the repaired mine abandoned again.
