Embodiment Construction

[0034] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the implementation manners of the present invention will be further described in detail below.

[0035] The present invention provides a kind of open-pit mining gravel soil slope regreening technology of green mine, comprising the following steps:

[0036] The first step: slope shaping;

[0037] Slope cutting treatment is carried out on the convex or steep part of the slope after open-pit mining, and finally the slope ratio of the slope is controlled between 0.6 and 0.8, and a horizontal platform in the middle of the slope and a horizontal platform on the top of the slope are set in the middle of the slope. The width of the horizontal platform in the middle of the slope and the horizontal platform at the top of the slope is 5 meters to 8 meters, and the large pieces of gravel and dangerous stones within a certain depth from the surface of the slope surface are c...

Abstract

The invention relates to the technical field of mine ecological management, and particularly discloses a gravelly soil side slope regreening technology for green mine open-pit mining. The gravelly soil side slope regreening technology involves the steps of side slope shaping, side slope overall reinforcement, soil replacement backfilling and laying, water storage and drainage irrigation system building, maintenance, recording and the like. According to the side slope regreening technology, the plant survival rate is high, water and soil loss of a mine side slope is small, the ecological environment of a mine is effectively improved, geological disaster hidden dangers such as mine side slope landslide are eliminated, and certain ecological benefits and social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of open-pit mining in mines, and in particular relates to a technology for regreening gravel soil slopes in open-pit mining in green mines. Background technique [0002] The country's economic situation is constantly developing, and the demand for natural resources is increasing, especially for mineral resources such as coal, iron ore, and decorative stone. Open-pit mining, also known as open-pit mining, is a process of removing the covering on the ore body, obtaining the required minerals, and extracting useful minerals from the open-surface mining field. Compared with underground mining, open-pit mining has the advantages of full resource utilization, high recovery rate, low dilution rate, suitable for large-scale machinery construction, fast mine construction, large output, high labor productivity, low cost, good working conditions, and safe production . [0003] The waste rocks and gravel soil edges le...
