FIELD: mining.
SUBSTANCE: flattening of quarry sides is done bottom-up by means of their filling by application of stronger rocks taken from the bottom of the quarry. Filling may be carried out up to various vertical elevations at the board of the quarry depending on mine technical conditions of deposit bedding.
EFFECT: accelerated process of damaged lands recovery by increasing stability of flattened boards of the quarry to erosion processes, by arrangement of water reservoirs in the mined area with parameters favourable for recovery of their biological productivity.
