Problems solved by technology

However, due to the incomplete environmental protection measures for tailings ponds constructed in the early stage, there are relatively large hidden dangers of environmental pollution. With the continuous improvement of environmental protection needs, the environmental pollution problems of tailings ponds left over from histor

Abstract

The invention provides an environmental risk prevention and control integrated system and method for a historical remaining tailing pond, and relates to the technical field of environmental risk prevention and control of tailing ponds. The environmental risk prevention and control integrated system for the historical remaining tailing pond comprises a flood intercepting ditch, a blocking and anti-seepage layer group and a vertical anti-seepage wall, wherein the flood intercepting ditch is arranged around the tailing pond and is used for preventing rainwater outside the pond from scouring the tailing pond; the blocking and anti-seepage layer group is laid on the pond surface of the tailing pond and is used for blocking the rainwater from vertically seeping into the tailing pond; and the vertical anti-seepage wall is arranged at an underground water leakage path of the tailing pond and is used for blocking underground water from leaking. According to the environmental risk prevention andcontrol integrated system for the historical remaining tailing pond, a flood intercepting ditch structure around the pond, a vertical anti-seepage structure and a horizontal blocking structure are combined, the concentration of cyanide in the anti-seepage wall does not exceed the standard concentration after treatment, the rainwater outside the pond cannot scour the tailing pond, underground water pollutants are blocked on the inner side of the vertical anti-seepage wall, and the water quality of the underground water at the downstream of the tailing pond can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of tailings pond environmental risk prevention and control, in particular to an integrated system and method for environmental risk prevention and control of historical tailings ponds. Background technique [0002] The ore mined by metal or non-metal mines is called tailings, and the waste residue produced after mineral processing and selection of valuable concentrate products is called tailings, and the tailings disposal site is called tailings pool. According to different terrain conditions, tailings ponds can be divided into valley type, mountainside type, flat land type and river cut-off type tailings ponds. Among them, the valley type tailings ponds have the largest number due to their large storage capacity and low cost. [0003] At present, there are more than 12,655 tailings ponds in the country. Tailings pond enterprises are relatively concentrated along with the distribution of mineral resources, a...
