Molybdenum ore tailing sand reinforcing and anti-seepage method and building structure

Abstract

The invention relates to a molybdenum ore tailing sand reinforcing and anti-seepage method and a building structure. Molybdenum ore tailing sand is stacked along a canyon slope by using a canyon formed by a mine mountain body and a side mountain body, a tailing dam is built at the downstream of the canyon, and the tailing sand is divided into a powder surface layer and a powder base layer; a spiral drilling machine is used for drilling on the surface layer of the powder, the drilling depth reaches the interior of the powder base layer, a spiral conveying mechanism of the spiral drilling machine is used for filling curing agent slurry while outputting excavated tailing powder, a drilling track is of a latticed structure, and a latticed mineral powder curing wall is formed after the curing agent slurry is solidified; and then, a mineral powder curing roof is laid at the top of each unit grid of the latticed mineral powder curing wall, and a gap of 5-10 cm is formed between every two adjacent mineral powder curing roofs. The risk of dam breaking of the tailing dam can be greatly reduced, the safety of the tailing dam body is effectively ensured, and heavy metal pollutants of accumulated liquid obtained after tailing soaking on water and soil on the downstream portion of the tailing dam are remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of reinforcement and anti-leakage of tailings, in particular to a method for reinforcement and anti-leakage of molybdenum ore tailings and a building structure thereof. Background technique [0002] my country is a country with a large amount of molybdenum resources, its reserves rank second in the world, and a large amount of waste residue is produced every year. The tailings produced during the flotation process of molybdenum ore are tailings sand. Its main components are related to the origin and beneficiation process, and the chemical composition is complex and cannot be determined exactly. However, most of them contain metal minerals such as molybdenum minerals and iron ore, and non-metallic minerals such as albite, potassium feldspar, quartz and mica. In today's increasingly scarce resources, molybdenum ore "waste" is a potential secondary resource, but also an important strategic resource, which is ...

AI Technical Summary

Problems solved by technology

To sum up, there are two problems with the tailings dams that have been built at present: one is the high risk of dam failure; the other is that the risk of heavy metal pollution cannot be eliminated or reduced
