METHOD FOR FORMING A RECTANGULAR WASTE DUMP WITH AN ENVIRONMENTALLY FRIENDLY ORIENTATION Russian patent published in 2023 - IPC E21C41/32 

FIELD: mining.

SUBSTANCE: invention relates to mining, in particular to the development of deposits by an open method and the restoration of areas disturbed by open mining, and can be used in the extraction of minerals and the reclamation of rectangular rock dumps. A method for forming a rectangular waste dump with an environmentally friendly orientation, including the implementation of a pioneer dump embankment within the boundaries of a rectangular dump, formed bifurcated along the dump boundary to the left and right towards each other to the full design height of the tier, with simultaneous formation of reclamation along the perimeter of the outer slope of the rectangular rock dump under the tiers 5-7 m with slope angles in the range of 18-22°, with a slope of horizontal platforms towards the body of the dump, covered with a fertile soil layer, overburden intake of the quarry. When connecting the opposite boundary dump fronts of the tier, a dump embankment is performed with the development of the front of dump operations to the center of the designed dump body. The process is repeated when forming the next tiers of the dump up. A pioneer dump embankment within the boundaries of a rectangular dump is formed bifurcated along the dump boundary on the left and right to meet each other at the full design height of the tier. A dump embankment is performed with the development of the front of dump operations to the center of the dump body with the location of the short side of the rectangular dump front parallel to the axis of the wind rose vectors with the maximum value of the wind regime in this place according to long-term observations, as well as with the location of the axis of the entrance embankment of the rectangular dump parallel to the axis of the wind rose vectors with the maximum value of the wind regime and in the middle of the long side of the rectangular moldboard front. Reception of overburden rocks of a quarry is carried out in the mode of passing dumping in the direction of the wind at the current moment with the development of sectors of the front of dump operations to the center of a rectangular dump in the directions of the wind rose vectors in proportion to their length. A settling and quenching turbulent component of the dusting flow is formed inside the dumped slope of the tier of the rectangular dump front.

EFFECT: increasing the environmental efficiency of the dumped rock rectangular dump.
