摘要：
FIELD: mining.SUBSTANCE: invention relates to mining, mainly to open-pit mining, and can be used in reclamation pit openings after open mining. Proposed method comprises separate excavation, transfer and storage of soil layer and overburden in separate belt dumps, and mining of open-pit field. After the quarry is formed, at first, the trench is made with flattening the pit openings to slopes steepness, device of water-flooded pits is created for creation of water reservoirs, for this purpose at first there is flattening of pit edges to slopes steepness of not more than 12 degrees with further planning and strengthening of pit slopes along its entire perimeter by means of device of stepped terraces of various width and length, in the form of sites with insignificant inclination towards career slope, layer of stripping rocks with thickness of at least 30 cm is laid on each of terraces, its layer is compacted, then a layer of fertile soil together with mineral fertilizers is poured thereon and seeds of perennial grasses are sown, wherein each terrace along its perimeter is cased with low-growing bushes and connecting them between each other, starting from below upwards by laying stone tracks on a pre-arranged base from a layer of compacted drainage material with thickness of not less than 15 cm and a layer of sand with thickness of not less than 7 cm, wherein the tracks themselves are laid so that each subsequent track is directed in the opposite direction from the previous one, and shore strip of water reservoir is strengthened by layer of thickness of not less than 0.6 m of construction waste in form of broken burnt brick, concrete, reinforced concrete, ceramic tiles with subsequent compaction and laying sand-gravel layer with thickness of not less than 15 cm, then sand strip is poured, besides, pointwise, in places of connection of pit slope and sand strip trees are planted along the whole perimeter of water reservoir, and free sections of the open pit are filled wi
