Embodiment Construction

[0020] Such as figure 1 Shown, the invention provides a kind of improvement method of mine soil matrix, comprises the following steps:

[0021] S1: The soil in the mine reclamation area is leveled mechanically;

[0022] S2: Dig a number of trenches with a depth of 20-25cm on the soil surface of the reclamation area, and the distance between the trenches is 35-40cm;

[0023] S3: In the ditch according to 170-180g / m 2 The amount of soil conditioner applied;

[0024] S4: Apply 20-25g / m on the surface of the soil conditioner 2 The amount of application of microbial agents;

[0025] S5: Cover topsoil and plant vegetation on topsoil.

[0026] In the specific implementation of the present invention, the soil conditioner in the S3 step comprises 50-80 parts of guaronic acid mother liquor (100 times dilution), 120-170 parts of activated sludge, 5-8 parts of ammonium chloride, chlorine Potassium chloride 8-10 parts, fly ash 20-40 parts.

[0027] In another embodiment, the soil co...

Abstract

The invention discloses a method for improving the mine soil matrix. The method comprises the following steps: leveling the soil in a mine reclamation area through a machine; digging a plurality of ditches with the depth of 20-25cm in the soil surface of the reclamation area at the spacing of 35-40cm; applying a soil amendment to the ditches according to the amount of 170-180g / m<2>; applying a microbial agent to the surface layer of the soil amendment according to the amount of 20-25g / m<2>; and covering with surface soil and sowing vegetation on the surface soil. According to the method, the industrial waste source amendment and the microbial agent are applied to the soil, so that the content of organic matters, total nitrogen, alkali-hydrolyzable nitrogen, rapidly available potassium and available phosphorus in the soil of the mine reclamation area can be effectively increased, the purpose of improving the soil matrix is achieved, and ecological greening of the mine soil is achieved.

Description

technical field [0001] The invention belongs to the technical field of mine ecological restoration, in particular to a method for improving mine soil matrix. Background technique [0002] my country is rich in mineral resources, but coal mining has caused huge damage to land, vegetation, ecology and human settlements, resulting in a large number of subsidence areas and abandoned land. Although the land reclamation work in my country's mining areas was carried out earlier, the current land reclamation rate in my country is still significantly lower than that of developed countries in Europe and the United States. At present, the amount of coal mining in China continues to increase, and mining has caused serious damage to vegetation, soil and local ecosystems. At this stage, the problem of environmental management of mines has become very serious. How to successfully solve the problems of excessive damage to mines and further achieve the ultimate goal of a win-win situation i...
