A treatment method for the geological environment of abandoned mines with steep walls and deep pits

Abstract

The invention provides a geological environment treatment method suitable for a steep wall and deep pit type abandoned mine. The method comprises the steps of geological environment exploration, slope clearing treatment, mine pit backfilling, reinforced soil slope filling, retaining wall arrangement, rainwater drainage, slope crest water resistance, vegetation recovery, water storage preservation, deformation monitoring and the like. The specific environment conditions and the topographic features are effectively combined, artificial treatment is conducted on mine terrains formed by mining according to local conditions, and the good effect of recovering the geological environment of the abandoned mine is achieved. An artificial soil slope attaching steep wall which is filled with dump slag and local loess removes the potential geological hazards of collapse, slide and the like existing in steep wall and deep pit landforms, solves the problem that the land is occupied by mining wastes, and also facilitates vegetational cover and land restoration; mountains which recover green are fused together with surrounding natural mountains, the mountains recovering green and the surrounding natural mountains are synchronized in the four seasons, plants grow naturally, natural mountain appearance is recovered, and a contribution is made for national geological disaster control and ecological environment restoration.

Description

technical field [0001] The invention relates to a mine environment treatment method, in particular to a geological environment treatment method suitable for steep wall and deep pit type abandoned mines. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine scale (also known as production capacity) is usually expressed by annual output or daily output. Annual output refers to the amount of ore produced by a mine every year. According to the size of output, it is divided into three types: large, medium and small. The size of the mine should be compatible with the economically reasonable service life of the mine. Only in this way can we save infrastructure costs and reduce costs. In the mine production process, the mining operation not only consumes the most manpower, material resources, occupies the most funds, but also is the production link with the greatest potential to reduce mining c...

AI Technical Summary

Problems solved by technology

[0003] Due to the mining of the mine, the environment near the mine has been seriously damaged, and the ecological effect is very poor. However, the rock surface of the mine itself is steep, all exposed, and locally unstable, so there are hidden dangers of geological disasters such as collapses and landslides. The natural mountain is very uncoordinated, and the deterioration of the environment has also seriously affected the safety, life and work of local people.
