RECULTIVATION METHOD OF COMPARTMENT OF INWASH STORAGE UNIT, WHICH IS FILLED WITH WASTES Russian patent published in 2011 - IPC E21C41/32 E02B7/06 

FIELD: mining.

SUBSTANCE: method involves formation above the filled compartment of recultivation body from wastes with external surface of the specified convex shape and necessary for water flow and increase of the compartment capacity, and coating of external surface of recultivation body with layer of earth. At least lower part of recultivation body is formed in tiers, each of which is inwashed under protection of enclosing element installed along the tier perimetre by means of distributed outlet of pulp from pulp line so that sediment pond is formed in central part of tier and beach, which is specified on the basis of safety condition of width near the enclosing element providing the specified shape of external surface of recultivation body within the limits of the tier height. On wastes of beach zone of the compartment or tier of recultivation body there made is at least one water intake chamber in the form of the channel formed with dams and connecting the water intake facility to sediment pond. During tier-by-tier formation of recultivation body the dam crests of channels are maintained above water level in sediment pond, and water is supplied from channel by means of water intake facility to the water conduit of the water supply system of waste hydraulic transport. Length of channel section, which changes at inwash of wastes, from inlet threshold formed with wastes to water receiver of water intake facility 1k is brought into line with the following condition: L_channel≥(h_s-h_t)/i_underwater, where h_s - the specified water depth before water receiver of water intake facility; h_t - water depth at inlet threshold of the channel; i_underwater - average slope of the projection of underwater inwash of wastes.

EFFECT: simplifying the erection of water intake facility, its operation and inwash of sediment pond with wastes at final stage of recultivation, increasing the storage unit volume and improving the quality of water clarification before water intake facility.
