Description

Technical Field

[0002] A tailings pond refers to a place constructed by building a dam to block the valley mouth or enclosing land, used to store tailings or other industrial waste discharged from metal or non-metallic mines after ore sorting. The water in the tailings pond continuously penetrates along the pores between the tailings particles toward the downstream of the dam body to form seepage. The free water surface line of stable seepage is called the infiltration line. The higher the infiltration line is, the worse the stability of the pond body and the greater the possibility of pond collapse, which can easily cause serious accidents. By setting up seepage facilities in the tailings pond, it is possible to eliminate seepage in the tailings pond body, lower the infiltration line and enhance the stability of the pond body.

[0003] The tailings pond drainage device in the prior art is not easy to discharge the silt that enters the drainage well, and the silt is not easy to be discharged along the pipeline after being deposited, which affects the drainage effect. In addition, the practicality and durability of the tailings pond drainage device need to be improved. At the same time, the utility model patent with publication number CN208472698U discloses a tailings pond drainage device, including a vertical drainage shaft, a multi-layer drainage horizontal pipe radiating along the wall of the drainage shaft, and a water pipe drawn from the bottom of the drainage shaft and extending outside the tailings pond. The water pipe is connected to a drainage pool outside the tailings pond for collecting seepage water. A water pump for externally extracting seepage water is arranged at the end of the water guide pipe; radial holes penetrating the well wall are arranged on the drainage vertical shaft, and the drainage horizontal pipe is connected with the drainage vertical shaft through the radial holes, and the drainage horizontal pipe comprises a filter screen, an external skeleton, a water-permeable pipe and an internal skeleton from the outside to the inside; the water-permeable pipe is a corrugated seepage pipe, and the water-permeable pipe is composed of wave crests and wave troughs connected in sequence to form corrugations, and evenly distributed through water-permeable holes are arranged on the wave troughs, so it is not easy to discharge the mud and sand entering the drainage well, and it is difficult to filter completely by the filtering effect of the drainage horizontal pipe alone, and it is easy to block the drainage horizontal pipe, thereby affecting the drainage effect.
