Abandoned mine soil remediation method

Abstract

The invention discloses an abandoned mine soil remediation method. The abandoned mine soil remediation method comprises the following steps of trimming a mine waste disposal site, trimming the top ofthe mine waste disposal site to be a flat region, and trimming the slope of the sloping surface of the mine waste disposal site until the slope is smaller than or equal to 45 degrees; performing deepploughing and drying on the flat region twice; plowing the plat region twice; every 31-41 days, repeatedly plowing the plat region twice until the covering rate of earth surface plant covers in the plat region exceeds 40%, plowing the flat region once again, and during plowing, burying biomass strip bags to soil once again; spraying soil which is thoroughly decomposed after being fermented, with grass seeds to the sloping surface of the mine waste disposal site; enabling a transition plant cover hanging device to be arranged at the jointed part of the flat region and the sloping surface; enabling a plurality of water storing plant cover blocks to be hung below a plant cover zone in rows; transplanting bushes on vacant lots between the water storing plant cover blocks in rows on the slopingsurface, and transplanting bushes on the flat region in rows. According to the abandoned mine soil remediation method, plant covering of the mine waste disposal site can be rapidly repaired, water and soil can be effectively held, and generation of natural disasters can be avoided.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation and ecological restoration, in particular to a soil restoration method for abandoned mines. Background technique [0002] The development and utilization of mine mineral resources has effectively promoted the development of the national and local economy and society, but the mining of the mine has caused serious damage to the environment near the mine, and the ecological effect is very poor, and the rock face of the mine itself is steep and completely exposed. If the local area is relatively unstable, there are hidden dangers of geological disasters such as collapses and landslides, and it is not in harmony with the surrounding landscape and natural mountains. The deterioration of the environment has also seriously affected the safety, life and work of local people. Due to the complex landform of the abandoned mine, which is dominated by exposed steep slopes and gravel beaches,...

[0002] The development and utilization of mine mineral resources has effectively promoted the development of the national and local economy and society, but the mining of the mine has caused serious damage to the environment near the mine, and the ecological effect is very poor, and the rock face of the mine itself is steep and completely exposed. If the local area is relatively unstable, there are hidden dangers of geological disasters such as collapses and landslides, and it is not in harmony with the surrounding landscape and natural mountains. The deterioration of the environment has also seriously affected the safety, life and work of local people.

Due to the complex landform of the abandoned mine, which is dominated by exposed steep slopes and gravel beaches, the cultivation substrate artificially attached to the rocks will be gradually lost due to the erosion of rainwater on the cultivation substrate, which eventually leads to the failure of the greening project
