Problems solved by technology

[0002] With the development of the mining industry, the mine ecological environment, soil matrix, soil structure, groundwater, and biodiversity have been severely damaged. Many countries have also conducted research on the restoration of minerals. In the 1970s, the coal mines in the eastern plains of my country The ecological restoration work of some abandoned mines has been carried out sporadically. The traditional mine ecological restoration method has a relatively long restoration period and the restoration effect is not very great. The restored mines are easy to be abandoned again.

Embodiment 1

[0027] The present invention provides a technical solution: an ecological restoration method for abandoned mines, comprising the following steps:

[0028] S1: Sampling and testing the mine soil, and testing the soil in the abandoned mine to determine its pH, which can enable targeted restoration in the later stage;

[0029] S2: Find the soil source for restoration. In order to save money, you can find the soil source nearby. The type of soil source to be searched is strip-type covering soil or comprehensive soil covering. The soil source is spread on the surface of the mine, and the covering soil thickness of the restoration soil source is 5~10cm;

[0030] S3: Detect the soil source, and detect the pH and calcium ion content of the soil in the soil source;

[0031] S4: Acid mine restoration, preparing powder and solution of quicklime and carbonate, crushing and mixing the quicklime and carbonate in a pulverizer, and taking part of the quicklime and carbonate powder and water-d...

Embodiment 2

[0040] The present invention provides a technical solution: an ecological restoration method for abandoned mines, comprising the following steps:

[0041] S1: Sampling and testing the mine soil, and testing the soil in the abandoned mine to determine its pH, which can enable targeted restoration in the later stage;

[0042] S2: Find the soil source for restoration. In order to save money, you can find the soil source nearby. The type of soil source to be searched is strip-type covering soil or comprehensive soil covering. The soil source is spread on the surface of the mine, and the covering soil thickness of the restoration soil source is 2cm;

[0043] S3: Detect the soil source, and detect the pH and calcium ion content of the soil in the soil source;

[0044] S4: Acid mine restoration, preparing powder and solution of quicklime and carbonate, crushing and mixing the quicklime and carbonate in a pulverizer, and taking part of the quicklime and carbonate powder and water-diss...

Abstract

The invention discloses an ecological restoration method for an abandoned mine. The method comprises the following steps of S1, sampling and testing soil of the mine; S2, searching for a restoration soil source; S3, detecting the soil source, the pH of soil of the soil source and the content of calcium ions; S4, conducting acid mine restoration; S5, conducting alkaline mine restoration; S6, preparing a calcium ion solution; S7, conducting fertilization at regular time, wherein N fertilizer, P fertilizer, K fertilizer and other kinds of fertilizer can be applied at regular time to improve the soil fertility; S8, planting plants; S9, inoculating rhizobia, wherein the rhizobia are inoculated to the leguminous plants during planting; S10, introducing animals, wherein several groups of earthworms are freed in the soil source in the early stage; S11, observing restoration conditions. The restoration method is more scientific and reasonable, the soil activity is improved, improvement is accelerated, the mine restoration cycle is shortened, heavy metal ions in the mine can be enriched, germination and growth of the planted plants can also be promoted, and the structure, water permeabilityand ventilation of the soil can be improved.

Description

technical field [0001] The invention relates to the field of ecological restoration of abandoned mines, in particular to a method for ecological restoration of abandoned mines. Background technique [0002] With the development of the mining industry, the ecological environment of mines, soil matrix, soil structure, groundwater, biodiversity, etc. have been seriously damaged. Many countries have also conducted research on the restoration of minerals. In the 1970s, the eastern plains coal mining area of ​​my country Some ecological restoration work in abandoned mines has been carried out sporadically. Traditional mine ecological restoration methods have a relatively long restoration period, and the restoration effect is not very large. The restored mines are easy to be abandoned again. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an ecological restoration method for abandoned mines to solve the problems raised in the above background a...
