RECTANGULAR 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 rectangular 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 rectangular pyramids, 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 rectangular stripes for seedlings in the form of pine, birch, talin, which are executed with alternation to the side tops of inverted rectangular pyramid with stripes of meadow areas. Around the top of the inverted rectangular pyramid abandoned rectangular platform for artificial pond. Closed rectangular strips are made with the location of the short side of the base of the rectangular pyramid 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 rectangular pyramid. Dumps of the ditch are laid with a plow towards the top of an inverted rectangular pyramid.

EFFECT: increased environmental efficiency of the rock dump.
