Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] like figure 1 As shown, the regulation and ecological restoration method of the mine dump includes the following steps:

[0024] 1. Slope cutting and grading treatment:

[0025] First, according to the type of mine and the actual situation of the dump, the slope, slope length, and flat width of the dump that need to be remediated are determined empirically, and then the safety check is performed by calculation methods such as the limit equilibrium meth...

Abstract

The invention proposes a method for remediation and ecological restoration of a mine dump, which comprises: cutting the mine dump into three levels, the slope height of each level is 8m, the width of the horizontal step is 4m, and the slope ratio is 1:1.9 for the first level respectively. ~2.2, the second level 1:1.6~1.8, the third level 1:1.4~1.5; the surface of the horizontal step is subjected to local foreign soil, and the thickness of the foreign soil is 30cm; the slope surface is grouted and covered with soil; The slope adopts the mortar masonry arch frame, the slope bottom skirt, the drainage ditches on both sides of the slope, and the slope edge; 15cm horizontal planting ditch; sow herbs and native shrubs in the ditch, keep the soil 2-3cm on the surface moist, and maintain and manage it in time; plant cloves on the horizontal step surface of the slope. The invention adopts biological measures and assists certain engineering measures to comprehensively control the soil dump, and the cost is low.

Description

technical field [0001] The invention relates to an environmental protection method, in particular to a method for regulating and ecological restoration of a mine dump. Background technique [0002] The development of mineral resources has caused a large number of ecological and environmental problems. The environmental problems, safety problems, and occupation of cultivated land and forest land caused by the large amount of abandoned land generated by mine development have always been widely concerned and valued by the international community. Mine dumps, also known as waste rock dumps, refer to places where mining wastes are discharged intensively. As a place where mines receive large amounts of waste rock, the dump site is one of the basic processes of open-pit mining and an indispensable permanent engineering building for the organization of mine production. When the dump site is infiltrated by heavy rainfall or surface water, the stability of the accumulated materials i...
