Problems solved by technology

Under rainfall conditions, rainwater infiltrates into the covered soil or transformed soil. Generally, the soil cover layer is thin, and the interface between the exposed surface and the soil cover layer or the permeability coefficient of the dump site is large. At the same time, due to the leaching effect of rainwater, the nutrients in the soil are taken away, which cannot meet the needs of plant growth

Embodiment 1

[0031] A method for ecological restoration of mine engineering wounds, comprising the steps of:

[0032] a. Configure the nutrient soil in the room according to the specified ratio, add water and stir evenly, then fill the nutrient soil into the plant planting base plate, and plant the tree seedlings into the nutrient soil, cover the anti-evaporation plate, and plant the planting base After the plate is made, place it in a cool place for later use;

[0033] b. According to the climate characteristics of different regions, choose the appropriate season to place the plant planting base;

[0034] c. Before planting the arbor base plate, the base trench should be excavated in the mine restoration area;

[0035] d. Place the arbor planting base plate in the foundation groove, use water pipes to irrigate the base plate, stop after the water storage layer of the base plate is saturated, and then fill the gaps around the base plate with on-site soil;

[0036] e. After the on-site pl...

Embodiment 2

[0048] The invention is suitable for ecological restoration projects of engineering wounds such as exposed areas of mines and dumps, and can play the role of "water conservation and solidification" and reduction of heavy metal enrichment through the arbor planting base plate.

[0049] By constructing the arbor planting base plate, the soil is water-retained and solidified, and the arbor seedlings are given sufficient nutrients. The root system of surviving trees can improve the mine soil, promote the growth of soil microorganisms and the enrichment of mineral nutrients, and provide growth space for shrubs and grasses. -shrub-grass" mode transition.

[0050] Arbor planting base plate ( figure 1 , figure 2) consists of an outer structure 1, an evaporation pan 2, a nutrient soil 3, and tree seedlings 4.

[0051] The outer structure 1 is cylindrical and made of degradable anti-seepage material, with a diameter of 0.8-1.5m, a height of 0.8-1.2m, and a wall thickness of 3-5cm. ...

Abstract

The invention discloses a method for ecological restoration of mine engineering wounds, comprising the following steps: configuring nutrient soil, adding water and stirring evenly, layering and compacting the nutrient soil into a plant planting base plate, and planting arbor seedlings into the nutrient soil , cover the evaporation plate; according to the climate characteristics of different regions, choose the appropriate season to place the planting base plate; before planting the arbor base plate, dig the foundation groove in the mine restoration area; Use water pipes to irrigate the base plate, stop when the water storage layer of the base plate is saturated, and then fill the gaps around the base plate with on-site soil; after the site placement of the arbor planting base plate is completed, on-site observation and maintenance should be carried out every other month in the first year . The improved mine rock and soil in the present invention gradually changes to a nutrient-rich soil environment for plant growth. As time goes by, shrubs and grasses grow in the surrounding area, which further expands the improvement area of ​​the mine rock and soil, forming a virtuous cycle of the natural environment .

Description

technical field [0001] The invention relates to a method for ecological restoration of mine engineering wounds, which is used for ecological restoration of engineering wounds such as exposed mine areas and dumps, and belongs to the field of mine ecological restoration engineering. Background technique [0002] According to the 2014 national mine survey and monitoring, mine development covers an area of ​​2.2042 million hm 2 , accounting for about 0.22% of the country's land area. Mining occupies land resources, reduces land area, reduces soil quality, accelerates rocky desertification of mines, increases the risk of geological disasters, seriously pollutes groundwater, and has a great impact on natural resources and society. At present, the whole country is strengthening the construction of ecological civilization, and the ecological restoration of mines is in full swing. Among them, engineering wounds such as exposed mining surfaces and discharge sites are the main body of...
