METHOD FOR RECULTIVATION OF NON-WORKING SIDE OF QUARRY Russian patent published in 2022 - IPC E21C41/32 A01B79/02 

FIELD: mining.

SUBSTANCE: invention relates to mining, in particular to the development of open-pit deposits and the restoration of territories disturbed by open-pit mining operations; it can be used in the extraction of minerals and the reclamation of a non-working side of a quarry. A method for the reclamation of the non-working side of the quarry includes the terracing of the side with the formation of inter-ledge platforms with a reverse slope towards the side of the quarry and the application of a reclamation mixture on them. The formation of a reclamation layer is carried out from top to bottom by stages of reclamation by multiple transshipment of the reclamation mixture according to the principle from the upper platform to the lower one within the optimal group of ledges of the stage of reclamation of the non-working side of the quarry. Reclamation works are carried out in the following sequence: a bulldozer feeds rocks of quaternary deposits into the slope of the first ledge of the quarry in the direction of the center of the quarry, then, an excavator mounted on the formed bulk moves the bulk to the next inter-ledge platform from the surface while simultaneously forming a reclamation layer on each inter-ledge platform. For next stages of reclamation, the reclamation mixture is imported and stored in the form of quaternary deposits to the first inter-ledge expanded platform according to a transport scheme, then, the reclamation mixture is multiply transshipped from the upper platform to the lower one within the group of ledges of the next stage of reclamation with the simultaneous formation of a reclamation layer on each inter-ledge platform.

EFFECT: reduction in reclamation work on applying a reclamation layer to inter-ledge platforms.
