Problems solved by technology

However, in this method, the spraying base material is sprayed on the slope rock surface, which is not easy to fix. Although there is galvanized wire mesh, plants can only grow in the thinner soil layer bonded to the rock surface, and cannot grow. Into the rock, it is very easy to fall off, which reduces the effect of mine environmental restoration and treatment, resulting in a shorter maintenance time after restoration and treatment

Embodiment 1

[0042] The mine geological environment recovery management method of the present invention comprises the following steps:

[0043] 1) Topographic survey

[0044] Topographic survey, field investigation and statistical analysis were carried out on the NGZ area to be treated on the side of the expressway in BSK Town, GY City, Henan Province. According to the measurement and analysis results, the area to be treated in the NGZ is 0.133km 2 , the area to be treated is about 8.505hm 2 , including 10 pits with a total area of ​​79000m 2 ; There are 8 dangerous rock masses formed on the wall of the mining pit, with a total volume of about 3854m 3 ; There are 33 slag piles accumulated in various places in the mining pit, occupying an area of ​​6918m 2 , with a total volume of 24103m 3 ; There are 11 abandoned adit openings, all of which are left over from the mining of Ordovician limestone. The opening heights range from 3-15m, widths range from 4-6m, and depths range from 2-7m, o...

Embodiment 2

[0077] The difference between this embodiment and Embodiment 1 is that the irrigation pipelines are no longer buried, but the irrigation pipelines are arranged in drainage ditches and gutters. Specifically, the main pipeline is laid in the outer drainage channel of the flat land, and the branch pipes are laid in the inner drainage channel of the flat land, the slope drainage channel and the platform drainage channel, which greatly reduces the construction amount and facilitates the prevention of blockage. pipeline for repair.

[0078] The DFC area to be treated on the side of the highway in BSK Town, GY City, Henan Province is treated by the method of this embodiment. The area of ​​the governance area is 0.12km 2 , the main mine geological environment problem is that there are 10 mining pits with a total area of ​​20900m 2 , there are 18 large slag piles accumulated in various places in the mining pit, most of which are irregular in shape, with a total occupied area of ​​351...

Embodiment 3

[0081] The difference between this embodiment and Embodiment 1 is that for a slope with a slope angle not greater than 30°, fish scale planting pits are excavated on the slope, and the plant spacing of the fish scale planting pits is 2.0m, and the row spacing is 3.0m. Fill the fish scale planting pit with cover soil to form a cover soil layer, and then plant shrubs or trees on the cover soil layer.

[0082] The DFC area to be treated on the side of the highway in BSK Town, GY City, Henan Province is treated by the method of this embodiment. The area of ​​this governance area is 0.167km 2 , there are 22 mining pits with a total area of ​​92100m2 2 , 26 dangerous rock masses formed on the pit wall, with a total volume of 18642m 3 , 10 large slag piles accumulated everywhere in the pit.

[0083] After using the method of this embodiment to treat, 26 dangerous rocks were cleaned up, 10 waste residue piles were cleaned up, 22 pits were treated, and the land leveled 6.547hm 2 , ...

Abstract

The invention discloses a mine geological environment recovery treatment method and belongs to the technical field of geological environment restoration. The mine geological environment recovery treatment method comprises the following steps that slope cutting treatment is carried out on a side slope with the slope angle being greater than 30 degrees of a mining pit in a treatment area, slope cutting platforms are formed on the side slope, and stone obtained by the slope cutting treatment is collected; the stone collected in the step S1 is used as a filler for backfilling of the bottom of themining pit in the treatment area, and level block ground is formed; and soil dressing filling is carried out on the level block ground and the slope cutting platforms, a soil covering layer is formed,and greening plants are planted on the soil covering layer. According to the mine geological environment recovery treatment method, a side slope cutting and mining pit backfilling mode is adopted forthe mining pit of the treatment area, the slope cutting platforms are formed on the side slope, the level block ground is formed at the bottom of the mining pit, then the slope cutting platforms andthe level block ground are utilized, the greening plates are planted, the rock wall of the side slope can be shielded, and the greening area can be obtained to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of geological environment restoration, and more specifically, relates to a method for restoring and controlling the geological environment of mines. Background technique [0002] After mining, many pits or mining faces will be left, which will lead to problems such as unstable slopes, exposed rock mass, and lack of vegetation, which will lead to soil erosion and biodiversity degradation. lead to a serious imbalance in the ecosystem. At present, the method of covering vegetation is generally adopted for the restoration of mine geological environment. [0003] The Chinese invention patent with application publication number CN103422509A discloses a mine environment management method, including steps: slope cutting treatment: survey geological hazards, carry out slope cutting treatment on unstable slopes, and keep the slope angle less than 70°; risk removal: clear Hidden dangers of geological disasters, and c...
