Embodiment

[0028] Embodiment: A method for reclamation and greening of tailings slopes comprises the following steps:

[0029] (1) Investigation of tailings slag: Retrieve samples of tailings slag for analysis of physical and chemical properties;

[0030] (2) Ratio of main matrix materials: According to the physical and chemical properties of tailings slag, biochar and organic fertilizer are selected as matrix improvement materials, and the ratio of the three materials is adjusted by orthogonal design, and the optimal mass ratio of matrix materials is M 尾矿渣 :M 生物炭 :M 有机肥 =65:2:1, use this substrate to carry out reclamation and greening in the abandoned mining area;

[0031] (3) Select matrix additives: add 10g / m2 to the matrix according to the application amount 2 water retaining agent and 10g / m 2 the adhesive;

[0032] (4) Select seeds: select Amorpha fruticosa, seabuckthorn, purple fescue, cosmos, and Kochia with full granules and complete germs as planting plants, and the applica...

Abstract

The invention relates to a reclamation greening method for a tailing side slope. Tailing side slope tailing residues are selected as main substrate materials, charcoal and organic fertilizer are addedas an improving agent, and additives such as a water retaining agent and adhesives are added, the substrate is adopted for performing reclamation greening on the tailing side slope, amorpha fruticosa, red fescue, sea-buckthorn, coreopsis and kochia scoparia are adopted as target plants, the plant growth speed is high, resistance is high, the better ecologic repair greening effect is achieved, theslope protecting function can be enhanced, construction is convenient, maintenance is convenient, and the substrate adopted in the method is a soilless greening substrate, the cost is low, the repaired side slope soil environment quality meets the requirement for the secondary standard value of national environment quality standards (GB15618 1995), and the parallel effects of ecologic repair andslope protection are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection for ecological restoration of slopes in mining areas, in particular to a reclamation and greening method for tailings slopes. Background technique [0002] my country is a big country with extremely rich metal mine resources. It has a long history of mining, and the intensity of development and utilization of mines is high. A huge amount of tailings will be produced every year. During the long-term development and utilization of mineral resources, mine ecological damage and environmental pollution, etc. The problem is becoming more and more serious and has become an important restrictive factor affecting economic development and social stability. Tailings is a by-product of mine beneficiation. It is a solid waste with high moisture content that has no strength, contains pollutants, and is easy to liquefy and flow. According to statistics, the amount of existing tailings in my coun...
