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 mine engineering wound surface ecological restoration method. The method comprises the following steps that nutrient soil is prepared, water is added to be stirred to be uniform, then, the nutrient soil is layered and compacted, a plant planting base disc is filled with the nutrient soil, meanwhile, arbor seedlings are transplanted into the nutrient soil, and the nutrientsoil is covered with an anti-evaporation disc; for climate characteristics of different regions, a proper season is selected for placing the plant planting base disc; before an arbor base disc is planted, a base groove is excavated at a mine restoration region; the arbor planting base disc is arranged inside the base groove, a water pipe is adopted for watering the base disc, and watering is stopped after a base disc water storage layer is saturated, then, on-site soil is adopted for enabling peripheral seams of the base disc to be filled with the soil; after the arbor planting base disc is placed on site, on-site observation and maintenance can be performed every other one month at the first year. The improved mine rock soil body is changed gradually towards nutrient soil for plant growth, along with time passing, surrounding shrubs and thick grass grow, then, the mine rock soil body improving area is increased, and the virtuous circle of the natural environment is formed.

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...
