Embodiment Construction

[0035] Below in conjunction with each accompanying drawing, the present invention is described in detail.

[0036] Such as figure 1 Shown, a kind of non-ferrous metal mine waste rock yard ecological environment management method, comprises the following steps:

[0037] (1) Spray the slurry-like neutralizing and improving material onto the outer surface of the waste rock yard 1 through a mud spraying machine to form a neutralizing and improving layer 2;

[0038] (2) Spray the slurry-like buffering and insulating material onto the outer surface of the neutralization improvement layer 2 through a mud spraying machine to form a buffering and insulating layer 3;

[0039] (3) The slurry-like vegetation restoration material is sprayed onto the outer surface of the buffer isolation layer to form the vegetation restoration layer 4 by means of a mud spraying machine.

[0040] This method is a wet spraying method, using a slurry sprayer to spray high-concentration mixed materials onto ...

Abstract

The invention discloses a nonferrous mine waste rock storage yard ecological environmental management method. The method comprises the following steps that 1, by means of a slurry spraying machine, apasty neutralization and improvement material is sprayed to the outer surface of a waste rock storage yard, and a neutralization and improvement layer is formed; 2, by means of the slurry spraying machine, a pasty buffer isolation material is sprayed to the outer surface of the neutralization and improvement layer, and a buffer isolation layer is formed; 3, a vegetation recovery layer is formed onthe outer surface of the buffer isolation layer. Accordingly, wet spraying is adopted, a high-concentration mixed material is sprayed by adopting the slurry spaying machine to the waste rock storageyard, and specially for the neutralization and improvement layer, the pasty neutralization and improvement material is better embedded into a gap of an outer surface layer of the waste rock storage yard; compared with existing dry spraying machine spraying, the neutralization and improvement material can be sufficiently embedded, the problem that a large number of gaps are formed does not exist, and therefore due to sufficient embedding, even though the waste rock storage yard deforms slightly, a packing layer is not likely to fail.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a method for treating the ecological environment of waste rock storage yards in nonferrous metal mines. Background technique [0002] Non-ferrous metals are essential basic materials and important strategic materials for national economy, people's daily life, national defense industry, scientific and technological development. One of the characteristics of China's non-ferrous metal resources is that there are many composite ores, and some of them are of low grade. During the mining, smelting and processing of non-ferrous metal ores, a large amount of waste rocks, tailings, slag and other solid wastes are produced. [0003] Non-ferrous metal mine waste rock containing sulfur compounds and various associated metal minerals are easily oxidized and weathered after long-term exposure, which will cause collapse and other accidents. Alkaline, it is difficult to restore vegetation,...
