Application of Tailings Consolidation-Storage Process in a Mine Production
In an iron mine in Huoqiu County,Anhui Province,land are collected for the construction of the tailings pond in the early stage of construction.In the subsequent construction,the external conditions for the construction of the tailings pond are no longer available,leading to part of the land has been idle,re-sulting in a serious waste of land.In order to solve the problem of idle land and difficult disposal of mine tail-ings in the proposed tailings pond,the tailings are mixed with a certain amount of cementitious materials and dehydrated by using the tailings consolidation storage process,and then backfilled to the idle land for consolidation storage.According to the progressive storage method of'stage division and layered segmenta-tion',backfilling,soil covering and greening operations are carried out in small areas according to the plan to reduce the exposure time of stored tailings,which can reduce the environmental impact of the storage site,and at the same time alleviate the pressure of tailings disposal,the reuse of idle land and the promotion and demonstration of tailings disposal technology.
