Problems solved by technology

If a new tailings pond is built, there will be problems such as large investment, difficult land acquisition, large environmental impact, and long construction period; The dam, the built sub-dam body contains multi-layered clay interlayers, the dam body has a high soaking line, low structural strength, and poor dam body stability. If the upstream method is used to increase the height and expand capacity, it will be difficult, and the dam cannot be built high, and the expansion capacity is limited. And there is a hidden danger of dam instability

Embodiment Construction

[0008] Taking the tailings pond of Tongban Stone Mining Company as an example, the tailings pond is currently dammed by the upstream method, and it is currently at the end of its storage capacity and service life. The warehouse is heightened and expanded to solve the problem of continuous storage of tailings. With the uppermost sub-dam in the current production state as the fixed axis 1, the dam is built vertically in layers, and the tailings slurry is classified into coarse and fine particles by a hydrocyclone, and the coarse-grained tailings are discharged outside the dam to form a tailings sink. The sand accumulation body 2 and the fine-grained overflow tailings are filled into the reservoir to form a sedimentary body 3, thereby increasing the height of the original tailings reservoir. A water filtration rockfill dam 5 is built downstream of the dam 210m away from the fixed axis of the dam to protect the stability of the slope toe of the final dam body. In order to ensure ...

Abstract

A technology for increasing the capacity of tailing site for metal mine features that the dam of the said tailing site is further built upward vertically along the axis of upper sub-dam and a hydraulic cyclone is used to discharge the coarse particles outside the damp and stack the fine particles inside the dam. Its advantages include high effect, and high safety.

Description

[0001] Field [0002] The invention relates to the field of tailings stacking, in particular to a process for increasing the height and expanding the capacity of metal ore tailings storage. Background technique [0003] At present, most of the domestic metal ore tailings pools are in the middle and late stages of storage capacity and service life. In order to maintain the continuous production of mines, they are all looking for the best solution for the later storage of tailings to solve the problem of continuous storage of tailings. The solution: one is to build a new tailings pond, and the other is to transform the existing tailings pond. If a new tailings pond is built, there will be problems such as large investment, difficult land acquisition, large environmental impact, and long construction period; Dam, the sub-dam body contains multi-layered clay interlayers, the dam body has a high soaking line, low structural strength, and poor stability of the dam body. If you cont...
