A tailings pond separation dam structure and its construction technology

Abstract

The invention discloses a separating dam structure of a tailings pond and a construction process for the separating dam structure. The structure comprises an initial-stage separating dam and a separating dam body which are arranged in waste residues, wherein the separating dam body is arranged on the top of the initial-stage separating dam; a tailing pond inner seepage-proofing system is arranged among the initial-stage separating dam, each side of the separating dam body and the waste residues; the part from a tailings pond bottom to the side slopes at the two sides of the initial-stage separating dam is paved with the tailing pond inner seepage-proofing system; and paving and heaping elevation of each tailing pond inner seepage-proofing system and the separating dam body is higher than or equal to height of the waste residues. The separating dam is built between two different kinds of waste residues for isolating the two kinds of waste residues; and by virtue of the seepage-proofing systems at the two sides of the dam body, exudate of the waste residues at the two sides is not mixed with each other, so that damming engineering quantity is greatly reduced. According to the construction process, balance force of the waste residues at the two sides of the dam body is utilized for perpendicularly ascending a uniform section of the dam body, so that engineering quantity of a dam body material is reduced while waste residue separating requirements are met, and engineering investment is also reduced while a construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of tailings pond engineering, and in particular relates to a tailings pond separation dam structure and a construction process thereof. Background technique [0002] At present, most of the tailings ponds that have been built are piled up with a single type of waste slag, and no tailings separation dam is required. However, with the development and construction of industrial parks in various regions of the country, in order to facilitate the operation and management of tailings ponds and implement environmental protection regulations According to the policy, the state vigorously promotes the construction of public slag storage, so there are two or more industrial solid wastes stored in one tailings storage. If different types of waste slags are mixed and stored, it will lead to the synthesis of slag in the later stage. It is difficult to separate and collect different types of slag during recycling, and even...

Problems solved by technology

[0002] At present, most of the tailings ponds that have been built are piled up with a single type of waste slag, and there is no need to set up tailings separation dams. However, with the development and construction of industrial parks in various regions of the country, in order to facilitate the operation and management of tailings ponds and implement environmental protection According to the policy, the state vigorously promotes the construction of public slag storage, so there are two or more types of industrial solid wastes stored in one tailings storage. If different types of waste slags are mixed and stored, it will lead to the synthesis of slag in the later stage. It is difficult to separate and collect different types of slag during recycling, and even the mixing of different types of slag will produce toxic substances and cause environmental pollution
