Problems solved by technology

[0002] According to incomplete statistics, as of 2016, the number of abandoned mines in my country exceeded 12,000, and the stockpiled stripped objects exceeded 12 billion tons. Due to various reasons, the dumps formed by these stripped objects were not completely piled up according to the design requirements. On the one hand, it occupies a large amount of land, destroying the ecological environment and further deepening the desertification phenomenon; on the other hand, with the erosion of rainwater throughout the year, it has caused many natural disasters such as soil erosion and mudslides.
Although there are many technologies for slope reforestation, including hanging net spraying technology, fish scale pit excavation technology, planting trough technology, etc., most of them ar

Embodiment 1

[0024] Such as figure 1 As shown, a method for ecological slope protection of an abandoned mine dump in the present embodiment comprises the following steps:

[0025] (1) Slope finishing: conduct stability analysis and evaluation on the slope of the dump site through the calculation method of slope stability, and determine the area with potential landslide tendency, and carry out preliminary finishing on the slope form by cutting the slope and pressing the foot , the raw materials at the presser foot use geonet to add waste rocks and tailings from abandoned mining areas, and then remove dirt, waste, weeds, stones, tree roots and other sundries on the slope surface, and fill cracks and cavities exceeding 3.0mm After filling and compacting, it is necessary to ensure that the road surface is flat and free of cracks, so as not to hinder the bonding of the pavement and damage the geotextile;

[0026] (2) Base construction: Spray asphalt concrete evenly on the slope with a thicknes...

Embodiment 2

[0031] Such as figure 1 As shown, a method for ecological slope protection of an abandoned mine dump in the present embodiment comprises the following steps:

[0032] (1) Slope finishing: conduct stability analysis and evaluation on the slope of the dump site through the calculation method of slope stability, and determine the area with potential landslide tendency, and carry out preliminary finishing on the slope form by cutting the slope and pressing the foot , the raw material at the presser foot is to use geonet to add waste rock and tailings from the abandoned mining area, and then remove the dirt, waste, weeds, stones, tree roots and other sundries on the slope surface, and fill the cracks and cavities exceeding 1cm with filler Well and compacted, it is necessary to ensure that the road surface is flat and free of cracks, so as not to hinder the bonding of the pavement and damage the geotextile;

Abstract

The invention provides a method for ecological slope protection of an abandoned mine waste dump. The method comprises the steps of slope surface arrangement, base layer construction, film paving and net hanging spray-seeding. A spray-seeding matrix is mainly prepared from following raw materials including 100 parts of countryside soil, 20 parts of plant ash, 10 parts of humic acid, 8 parts of sawdust, 50 parts of drying sludge, 5 parts of cement and 2 parts of plant fibers. According to the method, bituminous concrete is paved on the slope surface, sinking of loosen soil in a side slope is weakened, and the strength of a rock-soil body of the slope surface is improved; by means of multiple layers of waterproof barriers, rainwater permeation is effectively stopped, meanwhile, a large quantity of tailings, waste stone and urban sludge can be consumed, and the region ecological environment is improved; and the engineering cost is low, and good social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of slope protection for mine dumps, in particular to an ecological slope protection method for abandoned mine dumps.
