preparation example Construction

[0033] In the present invention, the preparation method of the ecological restoration matrix in the mining area preferably includes the following steps:

[0034] The mountain soil, tailings sand, straw and organic fertilizer are mixed to obtain the ecological restoration matrix of the mining area.

[0035] In the present invention, the mixing of the mountain soil, tailings sand, straw and organic fertilizer is preferably specifically:

[0036] Mix mountain soil and tailings sand to obtain the main ingredient;

[0037] The main material is mixed with straw and organic fertilizer to obtain a mineral ecological restoration matrix.

[0038] In the present invention, there is no special limitation on the mixing process, and the mixing method well known to those skilled in the art can be used for mixing.

[0039] In the present invention, when the mining area ecological restoration matrix is ​​used for the mining area ecological restoration, it is preferable to add the mining area...

Embodiment 1

[0042] The mountain soil in the iron ore dump, the tailing sand in the tailings pond, and the decomposed chicken manure collected in the living area of ​​the mining village were air-dried and passed through a 5mm sieve, and the corn stalks collected in the living area of ​​the mining village were dried and pulverized. 3mm sieve;

[0043] Mix 75 parts by weight of sieved mountain skin soil with 25 parts by weight of sieved tailing sand, add 1 part by weight of sieved corn stalk and 3 parts by weight of sieved decomposed chicken manure, and mix to obtain Ecological Restoration Matrix in Mining Area.

Embodiment 2

[0045] The mountain soil in the iron ore dump, the tailing sand in the tailings pond, and the decomposed chicken manure collected in the living area of ​​the mining village were air-dried and passed through a 5mm sieve, and the corn stalks collected in the living area of ​​the mining village were dried and pulverized. 3mm sieve;

[0046] Mix 75 parts by weight of sieved mountain skin soil with 25 parts by weight of sieved tailing sand, add 3 parts by weight of sieved corn stalks and 3 parts by weight of sieved decomposed chicken manure, and mix to obtain Ecological Restoration Matrix in Mining Area.

Abstract

The invention provides a matrix for ecological restoration of a mining area. The matrix comprises the following components in parts by weight: 100 parts of main materials and 4-8 parts of auxiliary materials, wherein the main materials include hill-skill soil and mine tailing sand; and the auxiliary materials include straws and an organic fertilizer. According to the matrix, the mine tailing sand,the hill-skill soil, the straws and the organic fertilizer are used as the raw materials of the matrix for ecological restoration of the mining area, so that the recycle of production and domestic wastes in the mining area can be realized while the reclamation of the mining area is finished; the raw materials are not needed to be input from the outside of the mining area, so that the project amount and economic expense can be effectively reduced, and the higher environmental and social benefits are achieved. Known from a record of an embodiment that the matrix provided by the invention is used for a potted plant experiment, a tailing matrix is remarkably improved on the aspects such as field moisture capacity, volume and nutrients, and plants grow well.

Description

technical field [0001] The invention relates to mining area ecological restoration technology, in particular to a mining area ecological restoration matrix. Background technique [0002] my country is a big mining country in the world, and currently there are more than 200,000 various mines in our country. Mining activities have caused serious damage to the ecological environment of the mining area, and the ecological environment of the mining area needs to be repaired urgently. At the same time, the overall feature of my country's mineral resources is that they are rich but not rich, and 97% of them belong to lean ore or even ultra-lean ore. During the mining process, a large amount of mountain soil and tailings are accumulated, causing many environmental problems, and also posing a serious threat to the safety of life and property of the people in the mining area. In 2006, the reserves of tailings discharged by my country's mining production exceeded 10 billion tons, and...
