Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The invention provides a method for reducing the wetting surface of the dam slope of a mud-containing interlayer tailings dam, comprising the following steps:

[0025] Step 1, such as figure 1 As shown, according to the length of the dam body, the area of ​​the reservoir and the distribution of the mud interlayer 2 with a thickness of 1 m in the dam body, the position of the drilling hole is determined according to the elevation of the infiltration line 4 and the overflow position, and the drilling is carried out in the vertical direction on the dam slope. hole, the hole diameter of the drilled hole is The drilling depth extends to the drainage lens body 3 at the bottom of the dam body, and connects with the drainage lens body 3 to realize natural drainage. The drilling arrangement is based on the shortest distance from the wetting lin...

Abstract

According to the method for reducing the wetted surface of the dam slope of the mud-containing interlayer tailing dam, the drill holes are vertically formed in the dam body, penetrate through the mud interlayer and extend to the drainage lens body at the bottom of the dam body, and the non-fine concrete water permeable pipes are installed and wrapped with the anti-corrosion inverted filter geotechnical cloth to prevent the water permeable holes from being blocked; the non-fine concrete permeable pipe penetrating through the mud interlayer can quickly drain water in the mud interlayer to the bottom of the dam body, and the water is discharged into a confluence area under the dam through the drainage lens body. Water in the mud interlayer can rapidly infiltrate downwards through the non-fine concrete permeable pipe, so that the infiltration line of the dam body is effectively reduced, and the stability of the dam body is improved.

Description

technical field [0001] The invention belongs to the technical field of tailings pond engineering, in particular to a method for reducing the wetting surface of a tailings dam slope in a mud-containing interlayer. Background technique [0002] A tailings pond refers to a facility that intercepts the mouth of a valley by building a dam, and is used to accumulate and store the tailings slag produced in the mining, excavation and beneficiation process of metal or non-metallic mines, as well as the waste generated in the smelting process or other industrial waste slag. The construction of tailings ponds in my country mostly adopts the wet drainage method, which leads to the excessively high wetting line of the dam body and is prone to vibration liquefaction, which affects the stability of the dam body. When the tailings are discharged from the tailings pond, the tailings in the slurry are deposited in sequence according to their particle size: coarse, medium, fine, and mud. The ...
