Embodiment 1

[0058] Such as figure 1 As shown, an ecological restoration method for an abandoned slope of an acidic metal mine, the first nutrient base and the second nutrient base are sprayed to the slope 100, and the first nutrient base forms the first substrate layer 200 in contact with the slope 100, the first The dinutrient forms the second matrix layer 300 above the first matrix layer 200, and the thickness of the first matrix layer is 1.5-2 times the thickness of the second matrix layer.

[0059] In actual use, the first nutrient base includes the following raw materials in parts by mass:

[0060] 5.5-6.5 parts of sediment or tailings in the mining area

[0061] 4.5-5.5 parts of peat soil or humic acid organic fertilizer;

[0062] 3.5 to 4.5 parts of plant fiber;

[0063] 0.28 to 0.32 parts of soil micro-ecological improvement solution;

[0064] 0.025-0.035 parts of slow-release compound fertilizer;

[0065] 2.8 to 3.2 parts of low-alkali sulphoaluminate cement;

[0066] 0.28-...

Embodiment 2

[0100] Such as Figure 4-9 As shown, the present embodiment discloses a spraying device of vegetation nutrient base, which can be used in embodiment 1, and the spraying device includes:

[0101] The first profile 13 is used for laying at the bottom of the slope;

[0102] The second profile 14 is used for laying on the top of the slope;

[0103] The base 15 is slidably arranged on the first profile 13;

[0104] The first driving mechanism 16 is arranged on the first profile 13 and is used to drive the base 15 to move left and right;

[0105] The top seat 17 is slidably arranged on the second profile 14;

[0106] The second driving mechanism 18 is arranged on the second profile 14 and is used to drive the top seat 17 to move left and right, and the top seat 17 and the base 15 move synchronously;

[0107] Two steel wire ropes 19 arranged in parallel, one end of the two steel wire ropes 19 is relatively fixed to the base 15, and the other end is relatively fixed to the top sea...

Abstract

The invention discloses an ecological restoration method of an acid metal mine waste slope. The ecological restoration method comprises the following steps of spraying a first nutrient medium and a second nutrient medium to a slope, forming a first matrix layer in contact with the slope by the first nutrient medium, forming a second matrix layer positioned above the first matrix layer by the second nutrient medium, and ensuring that the thickness of the first matrix layer is 1.5-2 times that of the second matrix layer, wherein the second nutrient medium comprises seeds. The first matrix layer is free of sulfur powder and relatively high in alkalinity; the thickness of the first matrix layer is 1.5-2 times that of the second matrix layer; and the relatively thick first matrix layer can be reliably connected with a slope and conduct neutralization reaction, and enough depth can be provided for reliable growth of seeds of the second matrix layer.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to an ecological restoration method for abandoned slopes of acidic metal mines. Background technique [0002] For the abandoned slopes of acidic metal mines, the geology of the mines is extremely acidic, and the surface runoff water (about PH3.0) generated after rainfall contacts the slopes of the mines will not grow any grass, and the leached water will accelerate the erosion of the slopes of the mines. increase the risk of geological disasters. For the abandoned slopes of acidic metal mines, the existing repair methods are mainly not good for repairing. Contents of the invention [0003] Aiming at the above problems, the present invention proposes an ecological restoration method for the abandoned slopes of acidic metal mines. [0004] The technical scheme that the present invention takes is as follows: [0005] An ecological restoration method for an abandoned slope of ...
