Problems solved by technology

[0004] The surface layer of the acid metal mine solid waste dump is mostly gravel and slag, with loose structure and poor stability, it is difficult to store soil and water, plants cannot grow, and the ecological environment is difficult to recover naturally
In addition, due to weathering and rainfall leaching, toxic substances in solid waste can easily enter rivers and groundwater with precipitation, causing large-scale environmental pollution and ecological deterioration

Embodiment 1

[0034] 1. Stabilization of the storage yard. According to the management design of the solid waste storage yard, the stability of the solid waste storage yard is evaluated, and the necessary stabilization measures are implemented.

[0035] (1) Carry out slope cutting and load reduction for the accumulation body according to the steps with a slope length of 8m, and the width of the slope cutting platform is 1.5m.

[0036] (2) After the slope shaping treatment is carried out, the slope cutting platform shall be compacted to enhance the stability of the slope.

[0037] (3) Construction of slope drainage system: construction of slope drainage facilities, construction of intercepting ditches on the outer edge of slopes, laying of horizontal and vertical drainage ditches on slope cutting platforms and slopes. Considering the self-sinking status of the accumulation body, the cut-off ditch needs to be made of flexible materials, mainly ecological cut-off ditch and open / dark corrugated...

Embodiment 2

[0054] 1. Stabilization of the storage yard. According to the management design of the solid waste storage yard, the stability of the solid waste storage yard is evaluated, and the necessary stabilization measures are implemented.

[0055] (1) Slope cutting and load reduction are carried out on the accumulation body according to the steps with a slope length of 6m, and the width of the slope cutting platform is 2m.

[0056] (2) After the slope shaping treatment is carried out, the slope cutting platform shall be compacted to enhance the stability of the slope.

[0057] (3) Construction of slope drainage system: construction of slope drainage facilities, construction of intercepting drainage ditches on the outer edge of the slope, and laying of horizontal and vertical drainage ditches on the slope cutting platforms and slopes. Considering the self-sinking status of the accumulation body, flexible materials should be used for the intercepting drainage ditch, mainly ecological dr...

Embodiment 3

[0074] 1. Stabilization of the storage yard. According to the management design of the solid waste storage yard, the stability of the solid waste storage yard is evaluated, and the necessary stabilization measures are implemented.

[0075] (1) Carry out slope cutting and load reduction for the accumulation body according to the steps with a slope length of 5m, and the width of the slope cutting platform is 1m.

[0076] (2) After the slope shaping treatment is carried out, the slope cutting platform shall be compacted to enhance the stability of the slope.

[0077] (3) Construction of slope drainage system: construction of slope drainage facilities, construction of intercepting drainage ditches on the outer edge of the slope, and laying of longitudinal drainage ditches on the slope. Considering the self-sinking status of the accumulation body, flexible materials should be used for the intercepting drainage ditch, mainly ecological drainage ditch and open / dark bellows intercepti...

Abstract

The invention provides a vegetation recovery method for an acid metal mine solid waste stock dump, comprising the following steps of: stabilizing the stock dump; building a slope-surface water supply and drain system; carrying out anti-seepage isolation on a surface layer; filling and sealing the surface layer of the stock dump, so as to form a filling layer, and spraying and adsorbing a flexible anti-seepage isolation material, so as to form an anti-seepage isolation layer; paving vegetation cushions, and fixing in an anchoring way; paving bi-way geogrids, and fixing the geogrids and the vegetation cushions on the slope surface together by rivets; sequentially spraying plant-growing matrixes and seed layers; and covering vegetation carpets on the surface. According to the vegetation recovery method for the acid metal mine solid waste stock dump, the problem of environment pollution caused by various pollutants on the acid metal mine solid waste stock dump can be effectively reduced, a stock dump vegetation system can be recovered, the green vegetation area can be enlarged, and a good environment can be built.

Description

technical field [0001] The invention belongs to the field of ecological restoration, and relates to the ecological restoration of non-ferrous metal mine dumps, tailing ponds, mining faces and other special site conditions, in particular to a vegetation restoration method for acidic metal mine solid waste storage yards. Background technique [0002] Incidents such as "arsenic poisoning", "blood lead", and "cadmium rice" have occurred frequently, making heavy metal pollution one of the most concerned public events. At present, due to the mining, smelting, and processing of heavy metals in our country, many heavy metals such as lead, mercury, cadmium, and cobalt enter the atmosphere, water, and soil, causing serious environmental pollution. Environmental pollution caused by heavy metals or their compounds is extremely harmful to the environment and organisms. At the same time, it is easy to accumulate through the food chain, which has attracted great attention from scientists a...
