Tailing pond duty synergy system and method before pond closing

Abstract

The invention discloses a tailing pond duty synergy system and method before pond closing, and belongs to the field of tailing ponds. The tailing pond duty synergy system before pond closing comprisesa tailing pond and an in-pond sub-dike, a dry beach face is formed in the tailing pond, the in-pond sub-dike is built on the dry beach face so that an ore drawing area can be formed in the space between the in-pond sub-dike and a tailing dam of the tailing pond in the tailing pond, a drainage area can be formed in the space between the in-pond sub-dike and the pond tail of the tailing pond, the ore drawing area is used for storing tailings, and the drainage area is used for storing water. According to the disclosed tailing pond duty synergy system and method before pond closing, the empty storage capacity above the dry beach face in the tailing pond can be fully occupied, the maximum utilization of the storage capacity of the tailing pond is achieved, and favorable terrain conditions canbe created for pond closing engineering.

Description

technical field [0001] The invention relates to the field of tailings ponds, in particular to a system and method for increasing the efficiency of tailings ponds before closing the ponds. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. [0003] There are tens of thousands of tailings ponds in my country, and many tailings ponds have been in service in the middle and late stages. According to relevant national laws, regulations and norms, closed projects need to be carried out. Conventional tailings pond closure projects are covered with soil and greened according to the existing topographic conditions of the tailings pond, and flood drainage systems such as spillways are usually set up for flood discharge. [0004] In order to maintain the continuous development of mining ente...

AI Technical Summary

Problems solved by technology

[0005] The embodiment of the present application solves the technical problem in the prior art that the storage capacity of the tailings pond is not fully utilized and the tailings pond needs to be built after the tailings pond is closed by providing a system and method for increasing the efficiency of the tailings pond before the closure, and realizes In order to tap the potential and expand the capacity of the tailings pond from the service to the later stage, it can meet the stockpiling of tailings in the later stage. For mines in the later stage with a small ore surplus, it can avoid the problems of land acquisition, construction, and construction period caused by the new tailings pond. Can create favorable terrain conditions for closed warehouse engineering
