ELLIPTICAL ROCK DUMP EXTINGUISHED WITH AN ENVIRONMENTAL 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 ellipsoidal rock dump includes the lower base of the dump body along the terrain, the outer slopes of the tiers of the rock dump, formed by 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 elliptical 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 elliptical stripes for seedlings in the form of pine, birch, talin, which are executed with alternation to the side tops of inverted elliptical cone with stripes of meadow areas. Around the top of the inverted elliptical cone abandoned an elliptical platform for an artificial reservoir. Closed elliptical strips are made with the location of the short axis of the base of the elliptical cone parallel to the vector axis with the maximum value of the wind rose of the wind regime at a given location according to long-term observations in time intervals with negative temperatures. Ditches for biological reclamation in the form of planting seedlings are made along horizontal closed lines of the side surface of an inverted elliptical cone, ditches are laid with a plow towards the top of the inverted elliptical cone.

EFFECT: increased environmental efficiency of the rock dump.
