METHOD FOR FORMATION OF ROCK DUMP OF A ROUND SHAPE WITH AN ECOLOGICAL FOCUS Russian patent published in 2023 - IPC E21C41/32 A01B79/02 

FIELD: mining.

SUBSTANCE: development of deposits by an open method and restoration of areas disturbed by open mining, used in the construction of rock dumps. An eco-friendly round rock dump includes the preparation of lower base of the dump body along the terrain, dumping of the body, the outer slopes of the tiers of the rock dump, formed by simultaneous reclamation along the perimeter in subtiers of 5-7 m and with slope angles in the range of 18-22°, with a slope of the sites towards the dump body, covered with a fertile layer, the upper base of the dump surface is made by mining and biological reclamation. The upper base of the dump body is made in the form of lateral surface of inverted round cone, the top of which is located in the geometric center of the designed rock dump. The upper base of the dump body is divided into closed strips, in the form of segments of the lateral surface of the cone. For seedlings in the form of pine, birch, talina, seedlings are planted in closed lanes in a checkerboard pattern, which are performed with alternation to the sideof vertice of an inverted coneby stripes of meadow conical sites . Around the top of the inverted cone abandoned a cone platform for an artificial reservoir. Ditches for biological reclamation in the form of planting seedlings are made along horizontal closed lines of the side surface of an inverted round cone. Dumps of the groove are laid with a plow towards the top of the inverted cone. On the strips of meadow areas, a bumpy surface is made for snow retention in the form of ditches along the horizontal closed lines of the side surface of an inverted round cone, the dumps of which are laid with a plow towards the top of the cone.

EFFECT: increased environmental efficiency of the rock dump.
