Dry heap sealing and storing and pollution preventing method of heavy metal tailings
The invention discloses a dry heap sealing and storing and pollution preventing method of heavy metal tailings. The basic technology of the method is characterized in that an operation support of a dry tailing heap is formed through a support structure, a center tower and a bottom channel; the tailing heap is thoroughly separated from underground water by laying anti-seepage and waterproof bottom plates; the tailing water is circularly utilized through an infiltration water drainage method in the dry heap process, and waste water containing heavy metal is not drained outwards; and after the dry heap production is finished, the full surface of the tailing heap is sealed and greened, the penetration and exchange actions of surface water to the tailing heap are prevented, and therefore the tailing heap can be stored in the full-sealed and non-pollution state for a long term.
