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

FIELD: mining.

SUBSTANCE: invention relates in particular to development of deposits by an open method and restoration of territories disturbed by open mining. For implementation of the method of formation of the reclaimed watered rock dump with an environmentally friendly orientation the lower base of the dump body is aligned along the terrain. The outer slopes of the tiers of the reclaimed rock dump are formed with reclamation along the perimeter under the tiers of 5-7 m and with slope angles in the range of 18-22°, with a slope of horizontal platforms towards the body of the dump, the slopes are then covered with a fertile layer. The upper base of the dump surface is made with mining and biological reclamation. Top base of the dump body is made in form of a basing, the lowest point of which is located in the geometric centre of the planned dump. The upper base is divided into radial strips for seedlings such as pine, birch, willow and is made with alternating stripes of meadow areas towards the bottom of the basin. Around the lower point of the basing a platform for the lake is left. Grooves for biological reclamation in form of planting seedlings, are made along horizontal looped lines of the basin, grooves in the dump are laid with a plough at the lower point of the basin. To irrigate seedlings, water is supplied to the outermost groove and then the water flows into the next groove from the opposite side of the basin via the bypass channel groove in the dump to saturate the following grooves with moisture towards the lower point of the basin of the upper base of the dump body.

EFFECT: increasing the environmental efficiency of the reclaimed watered rock dump.
