Abstract

The invention discloses a tailing piling and storing system and method for reducing environment pollution. The tailing piling and storing system comprises a tailing concentration pool, a concentration tailing conveying pipeline and a tailing piling and storing yard, wherein the concentration tailing conveying pipeline comprises an ore feeding pipe, an overflow ore discharging pipe and a bottom flow ore discharging pipe; an ore feeding pipe of the tailing concentration pool is communicated with a tailing discharging pipe of a mine dressing plant; an overflow discharging pipe of the tailing concentration pool is communicated with a circulation water pipeline; a bottom flow ore discharging pipe of the tailing concentration pool is communicated with the tailing piling and storing yard; the bottom of the tailing piling and storing yard is provided with a waterproof compaction clay layer; a geotextile anti-seepage film is arranged on the compaction clay layer of the tailing piling and storing yard; a seeping and filtering water collecting system formed by a broken stone layer and a seepage discharging pattern pipe is arranged on the geotextile anti-seepage film; the lower side of the tailing piling and storing yard is provided with a water collecting pool. The system is reasonable, safe and reliable, the use is convenient, the zero discharge of tailing water is realized, the environment pollution of the tailing is reduced, and the stability loss or the dam breaking hidden danger of a tailing pond is reduced.

Description

technical field [0001] The invention relates to a tailings stockpiling system and method for reducing environmental pollution, which is suitable for the tailings processing field of a mine dressing plant, in particular to the tailings storage of the tailings of the dressing plant. Background technique [0002] As a by-product of mine beneficiation, tailings are a kind of solid waste with high moisture content that has no strength, contains pollutants, and is easy to liquefy and flow. At present, a large number of tailings in my country are mainly placed in tailings ponds. The environmental pollution of tailings ponds is mainly manifested in the harm to the environment caused by tailings wastewater, toxic and harmful substances, and the more serious harm to the environment caused by the dam failure of tailings ponds, mainly including surface water pollution and groundwater pollution caused by tailings wastewater , soil pollution, air pollution, radioactive pollution and other...
