Embodiment 1

[0036] This embodiment provides an ecological restoration system for abandoned mines, the restoration system comprising:

[0037] (1) Topography reconstruction project: including clearing the hard soil of the mine and filling it on the spot, collecting the gravel from the mine for recycling, demolishing the buildings to be rectified and transporting brick slag, land plowing, land leveling and piling up slopes.

[0038] (2) Drainage works: including the excavation of drainage ditches and the reinforcement of pit and pond slopes. The drainage ditches are dug by backhoe excavators, and the excavation points are dug from the downstream to the upstream of the drainage ditches , set water storage tanks at certain distances, and use submersible pumps to discharge water into the pits and ponds; when digging at the design level, personnel should be arranged in time to remove the remaining soil and dredge the accumulated water in the trenches to facilitate drainage. For trenches with po...

Embodiment 2

[0052] This embodiment provides an ecological restoration system for abandoned mines. On the basis of Embodiment 1, this embodiment also provides a new type of spraying material, which includes a natural adhesive layer, a porous substrate and Seed layer, the natural bonding layer includes 11 parts of common clay and 10 parts of starch, the porous substrate includes 30 parts of foamed silicic acid hydrogel, and the seed layer includes 20 parts of humus, 10 parts of organic fertilizer 2 parts, 2 parts of microbial agent and 15 parts of grass seeds.

[0053] The preparation method of the foamed silicic acid hydrogel is:

[0054] (1) Wash and dry the gravel collected in the mine, pulverize it in a pulverizer at 100°C and 700 r / min, and pass through a 60-mesh sieve to obtain gravel powder;

[0055] (2) Mix the crushed stone powder with 2mol / L NaOH solution, stir and react for 30min, filter and take the filtrate for later use;

[0056] (3) Mix the filtrate with 1mol / L sulfuric aci...

Embodiment 3

[0060] This embodiment provides an ecological restoration system for abandoned mines. On the basis of Embodiment 1, this embodiment is also provided with a drainage ditch 1, and the drainage ditch 1 is vertically arranged on the slope of the mine. The two sides are connected and alternately provided with a plurality of water storage tanks 2, the bottom surface of the water storage tanks 2 is 0.8m lower than the drainage ditch 1, and the bottom of the drainage ditch 1 is provided with a diversion groove 4, and the diversion groove 4 is formed by drainage The center of the bottom of the ditch 1 extends toward the water storage tank 2, and the first filter screen 5 and the second filter screen 6 are arranged side by side in the water storage tank 2, and the first filter screen 5 is close to the drainage ditch 1 and contains the barbed whiskers 7, so The mesh number of the second filter screen 6 is greater than that of the first filter screen 5, and the mesh numbers of the first fi...

Abstract

The invention discloses an abandoned mine ecological restoration system and its application method. The restoration system includes: (1) landform remodeling project: including clearing the hard soil of the mine and filling it on the spot, collecting the gravel of the mine for recycling, demolition Buildings to be rectified and brick slag transported abroad, land plowing, land leveling, and soil grading; (2) Drainage works: including excavation of drainage ditches and reinforcement of pits and ponds; (3) Landscape ecological restoration works: sowing grass seeds , Spraying grass seeds and green plant enclosures; (4) Other projects, signs and later management and protection. The abandoned mine ecological restoration system and restoration method provided by the present invention can effectively solve the problem of mine restoration through comprehensive restoration engineering design.

Description

technical field [0001] The invention belongs to the technical field of mine ecological restoration, and more specifically relates to an abandoned mine ecological restoration system and an application method thereof. Background technique [0002] In the process of urbanization, abandoned mines (quarries) have brought serious landscape ecological problems to the city, such as soil erosion, threats to urban flood control, reduction of biological diversity, damage to the surface, etc. , The sustainable development of the economy has a certain impact. In recent years, with the enhancement of my country's economic strength and the improvement of awareness of ecological environment protection, people are paying more and more attention to the ecological restoration and transformation of urban abandoned quarries, and to tap their hidden value. [0003] Mine ecological restoration is centered on the restoration of the ecological environment. It studies how to implement the restoratio...
