Abstract

The invention discloses a device and a method for upstream flood interception and drainage of a tailing pond. According to the method for upstream flood interception and drainage of the tailing pond, flood dams, flood guide and drainage tunnels and overflow facilities are constructed on an upstream side of the tailing pond to intercept most of flood under design standards and all daily surface runoff in an upstream drainage basin of the tailing pond by the flood dams and drain the same through the flood guide and drainage tunnels, a small part of flood beyond flood interception and drainage capacity in a flood peak time overflows to the tailing pond through the overflow facilities, and peak elimination is reduced by flood regulation storage capacity control of the tailing pond. By the method for upstream flood interception and drainage of the tailing pond, damming project amount of the flood dams is decreased, sections of the flood guide and drainage tunnels are reduced, project amounts of the flood guide and drainage tunnels is decreased as well, and accordingly investment is saved; in addition, sewage removal and flow distribution can be realized to protect the environment and water resources.

Description

technical field [0001] The invention relates to the technical field of mining, and more particularly, to a method and device for intercepting and draining flood upstream of a tailings pond. Background technique [0002] The flood interception and drainage method in the related art is to build a flood retaining dam upstream of the tailings pond to intercept all floods up to the design flood control standard of the upstream basin and drain them through flood diversion tunnels. The disadvantages of this method are that the amount of construction of the flood retaining dam is large, the section of the flood diversion tunnel is large, the investment is high, and the safety risk is large. Contents of the invention [0003] The present invention solves one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a flood interception and drainage method upstream of the tailings pond, which can reduce the amount of ...
