Mine ecological remediation and slope vegetation fast restoring method suitable for arid region

Abstract

The invention discloses a mine ecological remediation and slope vegetation fast restoring method suitable for the arid region. The method comprises a slope protection method and the steps that water collecting devices are arranged; soil improvement is carried out; vegetation configuration is carried out. Firstly, according to the through slope arrangement, mining slide slopes needing to be restored are subjected to step type slope cutting to be stabilized, an ecological catchwater is arranged on the inner side of each stage of a platform, and the steps are continuously provided with desilting basins and water collecting pits every other certain distance. Water collecting devices are mounted in the water collecting pits and connected with the desilting basins and the catchwaters, the other ends of the water collecting devices are provided with controllable drainage ports, the water collecting devices are connected with a slope irrigation system and used for collecting and fully and reasonably utilizing slope runoff, a dry season irrigation water source is provided, meanwhile, slope scouring is avoided, and water and soil losses are reduced. The platform and the slopes are all covered with earth, a planting pit is dug in each stage of the platform, the mode of ecological bags and ecological blankets is adopted in each stage of the slopes, a soil conditioner and foreign soil from other places are mixed, the planting pits, the ecological bags and the ecological blankets are filled with the mixture, and good water and fertilizer conditions are provided for plant growth. Proper trees brushes and grasses are selected to be distributed. The ground conditions of the side slopes are comprehensively improved, and side slope vegetations are restored to the natural ecological state.

Description

technical field [0001] The invention relates to an ecological restoration technology, in particular to a rapid vegetation restoration method suitable for ecological restoration of mine slopes in arid areas. Background technique [0002] With mining, especially open-pit mining, a large amount of land resources are occupied and destroyed, which seriously affects the health of the regional ecological environment. A large number of abandoned slopes are generated in mine pits, dumps, and tailings ponds. The slopes are unstable, the surface is exposed, and the vegetation is lacking. Causing serious geological disasters such as subsidence, collapse, landslide, environmental pollution such as air, water, soil, and other environmental problems such as soil erosion and biodiversity degradation, leading to the imbalance of the mining area ecosystem and seriously restricting the sustainable development of regional ecological society and economy . [0003] Aiming at the ecological probl...

Problems solved by technology

[0004] The current patents and research results are complex and diverse, aiming at some problems of ecological restoration of mine slopes in arid areas, but the purpose is too single, the restoration effect is not comprehensive, and there are problems such as poor ecology, low restoration rate, and short-term effect, which cannot be fundamentally solved Ecological Problems of Mine Slopes in Arid Areas
