Problems solved by technology

[0007] Patent No. 200910273478.0, the name is tailings pond surface purification and S. japonica ecological restoration method. The disadvantage is that the shallow surface is purified, covered with clay and then planted with vegetation. In this way, the labor intensity of workers is very high and the efficiency is very low, so it can only be operated manually. , it cannot be applied to factory production. For example, during the restoration process or just after restoration, the vegetation and very shallow clay will be washed away by heavy rain, making the vegetation survival rate very low and the covering effect very poor

Embodiment Construction

[0033] The mining area of ​​the present invention matches vegetation felt and the method for recovering ecology, and its steps are as follows:

[0034] ①Investigate the status quo of tailings pollution;

[0035] ② Factory production of vegetation felt;

[0036] ③ Tailing pond vegetation felt plant cultivation.

[0037] The investigation of the status quo of tailings pollution is to determine the oil pollution, acidity and alkalinity of the tailings and to determine the plants that can grow in this state:

[0038] Firstly, sampling tests were carried out on different plots in the tailings area, and the samples were divided into 10 small samples with the same shape and thickness of 700mm×700mm, and plants were selected for experimental planting on each small sample. The steps are as follows:

[0039] a. On-site reconnaissance and zonal testing, shallow sampling analysis of tailings ponds, testing the amount of oil, toxins and acidity in tailings;

[0040] b. Determine the for...

Abstract

The invention provides a method for ecological restoration by vegetation felts suitable for mining areas. The method is characterized by comprising the steps of A, investigating pollution situations of tailings, B, producing the vegetation felts in an industrialized manner, and C, performing plant cultivation on tailings pond vegetation felts. The method has the advantages that industrial and large-scale production can be performed at any time according to various situations of tailings ponds in the mining areas, labor intensity of workers during laying is low, and the whole process is high in production efficiency; and when the tailings ponds are reused for extracting minerals, only plants of the vegetation felts need to be removed, and the plants of the vegetation felts can be reused for covering tailings remainders with the minerals extracted.

Description

technical field [0001] The invention relates to the technical field of tailings treatment, in particular to a method for restoring ecology by selecting and configuring suitable vegetation felts according to the characteristics of mining areas and tailings ponds. Background technique [0002] On the one hand, the accumulation of tailings in my country is huge, which has also brought negative impacts on environmental protection; on the other hand, the comprehensive average recovery rate of mineral resources is less than 50%, only about 20%, while the average utilization rate of metal tailings It is less than 10%, which fully shows that the development of comprehensive utilization industry of tailings in our country is urgent, and comprehensive utilization is still needed for treatment. By creating a low-carbon life, developing a low-carbon economy, cultivating a low-carbon cultural concept of sustainable development, green environmental protection, and civilization, and forming...
