Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art such as high cost, long period and poor acid control effect. Based on the biological repair method, the acid-base balance is adjusted through lime, and the production of acid is blocked by physical isolation, so as to build a stable vegetation community and provide An ecological restoration method for copper mine oxidized ore waste rock stockpile with low cost, simple operation and stable effect

Embodiment Construction

[0027] In order to make the purpose and technical solution of the present invention clearer, the following will further clarify the present invention through the detailed description of specific embodiments, but it is not intended to limit the present invention, but only for illustration. In the following, the present invention will be further described in detail in conjunction with an example of ecological restoration of the waste rock field of Chengmenshan Copper Mine, Jiujiang County, Jiangxi Province.

[0028] The slope of the Chengmenshan Copper Mine waste rock site is about 60°, the soil is sandy and strongly acidic, the steep slope is severely scoured, the water retention capacity is poor, and there is almost no plant growth on the slope, and the soil contains copper, lead, zinc, and cadmium Many other heavy metals exceeded the standard. The ecological restoration project that the present invention implements, concrete steps are as follows:

[0029] (1) Clean up the sl...

Abstract

The invention discloses a copper mine waste oxidized ore hillock ecological restoration method. The method comprises the first step of land preparation, the second step of first layer grating laying, the third step of ecological bag slope protection, the fourth step of lime layer spraying, the fifth step of physical isolation layer laying, the sixth step of ecological bar erecting, the seventh step of second layer grating laying, the eighth step of soil matrix improvement layer spraying, the ninth step of seed layer spray-sowing, the tenth step of straw curtain covering and fixing and the eleventh step of water intercepting and drainage facility arranging. By means of the ecological restoration method, acid can be effectively isolated and controlled, and the effect of heavy metal and other pollutants on the surroundings can be controlled from a source.

Description

technical field [0001] The invention belongs to the field of soil ecological restoration, and in particular relates to a method for restoring vegetation in oxidized ore waste rock fields. Background technique [0002] Sulfide-containing ores interact with the hydrosphere, atmosphere and microorganisms under supergene conditions to produce acid mine water, which is an important source of environmental pollution in copper mines. Through the comprehensive use of physical, chemical and biological measures, building a stable vegetation community and preventing the generation and migration of acid mine water from the source are fundamental measures to solve the pollution of copper mine waste rock sites. It is very difficult to carry out ecological restoration in view of poor soil, extreme pH, and excessive copper in copper mine oxidized ore waste rock dumps, etc., and it is necessary to meet the barren-resistant, acid-resistant, and heavy metal-resistant treatment technologies at ...
