A kind of tailings pond mould bag dam grid storage structure and grid storage method

Abstract

The invention discloses a grid storage structure of a tailings pond mould bag dam and a grid storage method. The grid storage structure comprises a sub-dam, a first mould bag retaining dam and a second mould bag retaining dam which are arranged in sequence. . A tailings dry beach area is formed between the sub dam and the first mold bag retaining dam, and the tailings dry beach area is used to store graded tailings. A tailings discharge area is formed between the first mold bag blocking dam and the second mold bag blocking dam, and the tailings discharge area is used to store full tailings. A tail water clarification area is formed between the second mold bag retaining dam and the mountain, and a drainage structure is provided in the tail water clarification area. In the invention, a grid frame is formed by the first mould bag retaining dam and the second mould bag retaining dam, and the grid frame can guide the tailings relatively directionally and restrict the flow of the tailings, thereby reducing the tailings of fine particles entering the tail water with the water flow. Sand, as much as possible to keep the tail water as clear as possible to meet the requirements of environmental protection or to meet the requirements of safely raising the drainage elevation in the reservoir area. At the same time, the grid frame can improve the overall strength of the storage structure and reduce the risk of dam failure.

Description

technical field [0001] The invention relates to the technical field of tailings storage in wet discharge tailings pond, in particular to a grid storage structure and a grid storage method for a tailings pond mould bag dam. Background technique [0002] A tailings pond is a place used to store tailings or other industrial wastes discharged from metal or non-metallic mines after ore sorting. In traditional tailings ponds, tailings are generally discharged in front of the dam, and the tail water is stored and clarified at the tail of the dam, without grid setting. When the tailings entering the storage are ultra-fine, the rainwater will bring the surface tailings into the tail water, resulting in turbid tail water, and the clarification area cannot be clarified in time. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a tailings pond mold bag dam grid storage structure and grid storage method, which are used to avoid the tail water being m...

AI Technical Summary

Problems solved by technology

When the tailings in the storage are ultra-fine, the rainwater will bring the tailings on the surface into the tail water, resulting in turbidity of the tail water. The clarification area cannot be clarified in time, and the discharge of the tail water cannot meet the environmental protection requirements and cannot meet the discharge standards.
