Problems solved by technology

At present, the measure to prevent the initial dam from running muddy is to set up a clay inclined wall within a certain height range at the bottom of the upstream surface of the initial dam. Setting up a clay inclined wall will increase the project investment on the one hand, and on the other hand will weaken the drainage of the tailings accumulation dam to a certain extent.

Abstract

The invention discloses a modified mixed dam applicable to tailings ponds. The dam comprises a dam body, an upstream face impermeable layer, an impermeable tooth groove, a drainage piled rock prism body, an upstream face drainage layer, an upstream face inverted filter layer, an inverted filter tooth groove, a dam outer slope impermeable layer, a dam lower inverted filter layer, a dam lower drainage layer, a drainage pipe, a seepage collection pipe, a dam body and mountain contact surface impermeable layer, and a dam body and mountain contact surface drainage layer, wherein the upstream face impermeable layer is positioned among the dam body, the drainage piled rock prism body and the upstream face drainage layer; the upstream face drainage layer and the drainage piled rock prism body are positioned between the upstream face impermeable layer and the upstream face inverted filter layer; the drainage piled rock prism body is positioned below the upstream face drainage layer; the dam lower inverted filter layer is positioned between the dam body and the dam lower drainage layer; the drainage pipe is positioned in the dam lower drainage layer; the inlet of the drainage pipe is connected with the seepage collection pipe; a gate valve is arranged at the outlet of the drainage pipe; the seepage collection pipe is positioned in the drainage piled rock prism body. The dam has the advantages that local material can be adopted for damming, the damming cost is low, the running is reliable, the maintenance is convenient, and the function is comprehensive.

Description

technical field [0001] The invention relates to an improved mixing dam suitable for tailing ponds. Background technique [0002] At present, there are more than 12,000 tailing ponds in my country, with a storage capacity of more than 10 billion tons. The safety of tailings ponds is related to the safety of life and property of downstream residents and the pollution of the land environment. Especially in recent years, the frequent safety accidents of tailings ponds have brought great economic losses to the country, and the casualties caused by safety accidents have affected the society. harmony and stability. [0003] The safety problem of tailings pond is prominent, and the investment in safety facilities is also very large. The proportion of tailings pond construction investment in the entire mine construction investment is gradually increasing. How to reduce the engineering investment as much as possible while improving the safety factor of the tailings dam has become a...
