Tailings pond flood drainage system for draining in advance efficiently and prolonging clarification distance

Abstract

The invention discloses a tailings pond flood drainage system for draining in advance efficiently and prolonging a clarification distance. The tailings pond flood drainage system comprises a draining well and a flood drainage pipe, wherein the draining well comprises a well base, a headframe and an arched cover plate, the well base is provided with a casing pipe, a water inlet is formed in the headframe, the casing pipe is connected to the flood drainage pipe, a water inlet hole is formed in the top part of the flood drainage pipe, and non-woven geotechnical cloth wrapped concrete plug is used for blocking, so that inflow elevation of the water inlet hole of the flood drainage pipe is improved. The flood drainage system has the advantages as follows: 1) water drainage can be done in advance through a prepared hole of the flood drainage pipe based on a demand in the early period of the operation of the tailings pond, so that the purpose of accelerating solidification of tailings of a fill dam is realized; 2) water drainage can be done through the prepared hole of the flood drainage pipe based on a demand in the middle and later periods of the operation of the tailings pond, so that the purpose of prolonging the clarification distance of drained water outside the tailings pond, improving the clarification effects and reducing the environmental pollution is realized; 3) the blocking construction of the prepared hole of the flood drainage pipe is convenient, fast and economic.

Description

technical field [0001] The invention relates to a tailings pond flood discharge system, in particular to a tailings pond flood discharge system which can effectively discharge water in advance and prolong the clarification distance. Background technique [0002] Tailings pond is a special industrial building and one of the three mine control projects. Its operation is not only related to the economic benefits and production safety of mining enterprises, but also threatens the life and property of the downstream residents in the reservoir area and the surrounding areas. environment. [0003] The flood discharge system of the tailings pond is of great significance to the overall safety of the tailings pond. The flood discharge system must not only ensure the safe and timely discharge of clarified water and floods in the reservoir area, but also ensure that the tailings are not discharged from the flood discharge system. , that is, drainage does not discharge sand.
