Embodiment 1

[0032] A reinforcement and anti-leakage method for molybdenum ore tailings, which uses the canyon formed by the mine mountain and side mountains to stack the molybdenum ore tailings along the slope of the canyon, and a tailings dam for blocking the tailings is built in the downstream of the canyon. Enclose the entire tailings, and open a drainage hole on the tailings dam, divide the tailings sand into two parts: the powder surface layer and the powder base layer, and use an auger drilling machine to drill on the powder surface layer, and the drilling depth reaches the powder In the body base, the screw conveying mechanism of the auger drilling machine outputs the excavated tailings powder, and at the same time fills the drilled gap with curing agent slurry through the curing agent slurry delivery pipe at the rear end of the screw conveying mechanism. It has a grid structure, and the grid-like mineral powder solidification wall is formed after the curing agent slurry is solidifi...

Abstract

The invention relates to a method for strengthening and preventing leakage of molybdenum ore tailings and a building structure. The molybdenum ore tailings are stacked along the slope of the canyon by using the canyon formed by the mine mountain and the side mountains, and a tailings dam is built downstream of the canyon. Divide the tailings sand into two parts: the powder surface layer and the powder base layer, and use the auger drilling machine to drill on the powder surface layer until the drilling depth reaches the powder base layer. When the tailings powder is output, the curing agent slurry is filled on one side, and the drilling track is in a grid structure. After the curing agent slurry is solidified, a grid-shaped mineral powder solidification wall is formed; A slag solidified roof is laid on the top of a unit grid, and a gap of 5-10cm is provided between adjacent slag solidified roofs. The invention can greatly reduce the risk of the tailings dam breaking, effectively ensure the safety of the tailings dam body, and significantly reduce the heavy metal pollutants of the tailings soaked fluid on the water body and soil downstream of the tailings dam.

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 ...
