METHOD FOR RECLAMATION OF DISTURBED LANDS Russian patent published in 2009 - IPC E21C41/32 

FIELD: mining.

SUBSTANCE: invention is related to mining, mostly to open mining works, and may find application in reclamation of shallow borrow cuts after performance of open mining works. Method includes separate excavation, movement and stacking of soil layer and overburdens into separate band dumps, excavation of mine pit, filling of excavated space with construction wastes, composition of which is close to natural materials, layerwise, with compaction of each layer of construction wastes by compactor machines and mechanisms. At the same time soil layer and overburdens are transported into temporary band dumps located near mine pit borders on its inoperable sides. After mine pit excavation, construction wastes are laid at its bottom, starting from its centre. Then overburdens are dumped onto the last compacted layer of construction wastes, with preservation of hill surface of dump. After complete filling of excavated space of mine pit field, upper part of overburden dump combs are cut, and soil layer is placed into depressions between them, besides surfaces of cut combs are treated with binding material, and tree saplings are manually planted.

EFFECT: reduced distance of soil layer and overburdens transportation, synchronisation of processes on performance of getting and reclamation works, reduced area of lands alienation for development.
