specific Embodiment approach

[0040] As a specific implementation of the design method for reducing the structure of the wet discharge tailings pool infiltration line provided by the present invention, please refer to figure 1 , including the following steps:

[0041] (1) Determine the design position of the infiltration line 7 according to the characteristics of the tailings pond;

[0042] (2) Referring to the design position of the wetting line 7, calculate and determine the angle θ between the equivalent bottom slope line 8 formed at the front end of the anti-seepage layer 3 and the horizontal direction;

[0043] (3) Determine the number of laying anti-seepage layers 3 and the position interval of each anti-seepage layer 3 .

[0044] In this embodiment, first, according to the characteristics of tailings ponds, combined with the requirements of the "Tailings Pond Safety Technical Regulations" and "Tailings Facilities Design Specifications", the design position of the infiltration line 7 is determined; ...

Abstract

The invention provides a structure and a design method for reducing the infiltration line of a wet-discharge tailings pond, belonging to the technical field of tailings pond design and structure, and the structure for reducing the wet-discharge tailings pond includes a dam body and a Seepage layer, the dam body is set on the ground; there are several anti-seepage layers, the anti-seepage layer is set in the dam body and closely fits with the dam body, several anti-seepage layers are arranged at intervals, and the anti-seepage layer is horizontal or parallel to Laying on the dry beach surface, one end of several anti-seepage layers is connected to the ground, and the other end of several anti-seepage layers is located on the same oblique line, and the oblique line passes through the intersection of the inner slope surface on the side of the initial dam near the anti-seepage layer and the bottom surface of the initial dam. The structure provided by the present invention for reducing the infiltration line of the wet discharge tailings pond is provided with an anti-seepage layer to form an equivalent bottom slope line, which increases the bottom slope of the tailings pond, thereby reducing the infiltration line. The design method for reducing the infiltration line of the wet discharge tailings pond facilitates the determination of the parameters of the structure for reducing the wet discharge tailings pond's infiltration line, and ensures the accuracy of construction.

Description

technical field [0001] The invention belongs to the technical field of tailings pond design and structure, and more specifically relates to a structure and a design method for reducing the infiltration line of wet discharge tailings pond. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. Most of the existing tailings facilities at home and abroad are traditional wet-discharge tailings ponds. In my country, wet-discharge tailings ponds account for more than 95%. The free liquid surface in the seepage field of the tailings pond is called the "wetting line". The stability of the tailings dam is the main measure of the safety of the tailings pond, and the infiltration line of the tailings pond is buried shallowly, which is prone to dam failure. Contents of the invention [0003] ...
