Waste mine restoration method based on biological habitat restoration

Abstract

The invention discloses a waste mine remediation method based on biological habitat remediation. The waste mine remediation method comprises the following steps: S1, investigating of the current situation of a waste mine: a step of checking the damage and pollution degree of the mine, collecting some soil for detection at the same time, and checking the polluted degree of the soil so as to distinguish which part of the soil is severely polluted and which part of the soil is not severely polluted. The waste mine remediation method provided by the invention has the following beneficial effects:the soil can be remediated; meanwhile, plants can be planted according to soil conditions; the survival rate of the plants is greatly improved; large-area coverage of a large amount of nutrient soil is avoided; through drainage ditch construction, surface water flowing through a mining area is discharged to a downstream, so the length and the contact time of rainwater flowing through polluted soilof the mining area are reduced; the planted plants can effectively maintain the erosion resistance of water, soil and the ground surface, so the remediation effect of the mine is greatly improved; meanwhile, the remediation time is shortened, and great convenience is brought to users.

Description

technical field [0001] The invention relates to the technical field of abandoned mine restoration, in particular to an abandoned mine restoration method based on biological habitat restoration. Background technique [0002] With the development of mineral resources, especially the unreasonable development and utilization, serious ecological problems have been caused. These problems have seriously affected the ecological security of the country and directly threatened the production and life of the people in the mining areas. In the mining or mining area and a large amount of solid waste, the heavy metal content is too high. The solid waste residue of the mine is washed and leached by rainwater, and the toxic and harmful components in it are easily infiltrated into the soil, causing soil acidification, and it is concealed and long-term. , leading to soil environment deterioration, vegetation degradation, and biodiversity imbalance. Because many abandoned metal mines contain ...

Problems solved by technology

In the mining or mining area and a large amount of solid waste, the heavy metal content is too high. The solid waste residue of the mine is washed and leached by rainwater, and the toxic and harmful components in it are easily infiltrated into the soil, causing soil acidification, and it is concealed and long-term. , leading to soil environment deterioration, vegetation degradation, and biodiversity imbalance

Many abandoned metal mines contain a large amount of sulfur minerals, and the soil acidification and heavy metal pollution of long-term exposed abandoned mines have greatly increased the cost of ecological restoration and seriously restricted the sustainable development of the local economy and society.

At present, the ecological restoration of the exposed wasteland of metal mines is a worldwide problem. It is a huge challenge to establish a safe, stable and self-sustaining vegetation. However, the traditional ecological restoration methods of mines have a relatively long restoration cycle and the restoration effect is not good. It is very large, and covers a large area with a large amount of nutrient soil, which not only increases the cost, but also increases the repair time, which brings great inconvenience to users. For this reason, we provide an abandoned mine restoration method based on biological habitat restoration
