Abstract

The invention discloses an ecological restoration method for a high and steep slope in an open pit of a metal mine and an application thereof. The ecological restoration method comprises the followingsteps of: performing stabilizing treatment on the high and steep slope, constructing intercepting ditches and drainage ditches on the platform and edges of the slope, laying ecological rods and chainlink fences on the slope surface in sequence, constructing flexible V-shaped planting troughs on the slope surface by adopting the ecological rods, spraying light mixed slurry to form a light mixed substrate layer which completely covers the chain link fences, filling and levelling up the flexible V-shaped planting troughs by adopting planting substrates, spraying on the surface of the light mixed substrate layer to form a seed-erosion resistance integrated layer, and planting woody plants and/or vines in the flexible V-shaped planting troughs. The ecological restoration method can ensure thestability of plant growth media, creates acid-base conditions for normal growth of the plants, constructs good plant growth environments, a diversified vegetation restoration model, and a three-dimensional community structure of trees, shrubs and grass, and has great environmental benefits and social benefits; and the process is simple, is easy to implement, and has a good effect and great significance of large-scale promotion.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and relates to an ecological restoration of an open-pit stope of a metal mine, in particular to an ecological restoration method for a high and steep slope of an open-air stope of a metal mine and an application thereof. Background technique [0002] Metal mines have a large proportion of sulfides in minerals, especially metal deposits such as copper, lead and zinc, accounting for about 75% of the total amount of various minerals. [0003] Affected by mining activities, the topsoil of the open-pit stope has been stripped, the surface morphology has been changed, the original surface has lost its original characteristics, and there are still many extreme physical and chemical properties that endanger the environment. [0004] Specifically, the main characteristics of the open-pit stope include: large slopes, most of which are between 70-90°, and even inverted rocks, and the slope he...
