Repairing method for side slope of mine dump

Abstract

The invention relates to a repairing method for a side slope of a mine dump and belongs to the technical field of side slope repair. The repairing method comprises the following steps of: planting trees, shrubs and herbaceous plants on the side slope of the mine dump; and planting the trees and the shrubs in the bottom layer, planting leguminous plants in the middle layer, and planting the herbaceous plants in the surface layer. By the adoption of the repairing method, the arbors, the shrubs and the herbaceous plants are combined, deep and shallow root systems are combined, herbs and woody plants are combined, legumes and gramineae are combined, pioneer species, auxiliary species, occasional species, constructive species and dominant species are combined, layered sowing is adopted, so thatgrowth and development nodes of different species are different, the growth and development nodes of biology are stagger, and competition of plants on nitrogen, phosphorus, potassium, other trace elements, space, sunlight and water is retarded; multi-species mixed sowing is adopted, so that intra-species competition and the inter-species competition are reduced and a survival rate is improved; seed size and sowing depth are different, so that the seedling emergence time is different, the seedling emergence time is prolonged, and the risk of large-area death of a seedling group caused by short-time drought in a seedling stage is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of slope repair, and in particular to a method for repairing a slope of a mine dump. Background technique [0002] Dump site, also known as waste rock site, refers to the place where mining waste is discharged intensively. The dump site is a huge artificial loose cushion body, which has serious safety problems. The instability of the dump site will lead to mine soil disasters and major engineering accidents, which will not only affect the normal production of the mine, but also cause the mine to suffer huge losses. Economic losses. [0003] At present, the main disadvantages of dump site restoration are as follows: [0004] The green restoration effect is not ideal or the natural recovery is slow; after restoration, there are many gullies and deep gullies in the slope area; a large area of ​​trees is planted, and the survival rate is low; there are many bald spots and a large area of ​​bald spots; the wate...

Problems solved by technology

[0004] The green restoration effect is not ideal or the natural recovery is slow; after restoration, there are many gullies and deep gullies in the slope area; a large area of ​​trees is planted, and the survival rate is low; there are many bald spots and a large area of ​​bald spots; the water demand is large after planting, and it is easy to degrade
