Integrated flood discharging system for tailing pond flood-sewage diversion and ore pulp conveying

Abstract

The invention discloses an integrated flood discharging system for tailing pond flood-sewage diversion and ore pulp conveying and belongs to the technical field of tailing ponds. The integrated flood discharging system aims at solving the problems that flood-sewage diversion of existing engineering is poor, and a tailing conveying pipeline is difficult to repair and maintain. The integrated flood discharging system comprises a flood-discharging main tunnel, the upstream side of the flood-discharging main tunnel communicates with a flood-discharging branch tunnel and a tailing conveying branch tunnel, a cutoff wall is arranged in the flood-discharging main tunnel, a water return canal is defined by the cutoff wall and the side wall of one side of the flood-discharging main tunnel, a cover plate is arranged on the position, in the flood-discharging main tunnel, of the upper part of the water return canal, a tailing conveying pipeline is arranged on the cover plate, a clear water channel is formed by the cutoff wall and the side wall of the other side of the flood-discharging main tunnel, the downstream side of the clear water channel communicates with a force dissipating pool, the downstream side of the water return canal communicates with a water return pool, a flood blocking dam, a tailing initial dam and a tailing accumulation dam are further included, and a seepage discharging blind ditch is arranged between the flood blocking dam and the tailing initial dam and communicates with the clear water channel side of the flood-discharging branch tunnel. The integrated flood discharging system is suitable for tailing pond flood-sewage diversion and ore pulp conveying.

Description

technical field [0001] The invention belongs to the technical field of tailings ponds, and in particular relates to an integrated flood discharge system for flood and sewage diversion and slurry transportation of tailings ponds. Background technique [0002] According to the natural geological conditions of our country, most of the tailings ponds built on the ground exist in valleys. The construction investment of the tailings pond project is mainly concentrated in two parts: the tailings dam body and the flood drainage system. At present, the common forms of flood drainage system are flood dam + chute + culvert flood discharge system and overflow well + tunnel flood discharge system. The purpose of setting up the flood drainage system in the tailings pond is twofold: one is to remove the heavy rain in the pond in time; the other is to recover the clarified water in the pond. In the past few decades, due to the lack of formal design and insufficient environmental protectio...
