REMOVAL OF ROCK BY LIGHT VEHICLES OF INCREASED CARRYING CAPACITY AND FAN SPREADING THEREOF TO DUMPS FROM OPEN-PIT ROADS BY MEANS OF SPREADERS Russian patent published in 2025 - IPC E21C41/26 E21C47/00 

FIELD: mining.

SUBSTANCE: group of inventions relates to mining. Disclosed is a method for removal to dumps of rock with light vehicles of increased carrying capacity, in which, in order to increase the efficiency of the used vehicle, the body tilter is excluded from its design with its replacement with a stationary mechanism mounted on the spreader, and also eliminated weighting caused by operation of vehicle at a distance from maintenance bases, and to increase vehicle speed, prepared tracks of dumpers are used. Also disclosed is a method of dumping rock into dumps from open pit roads, in which when the spreader has an unloading console, the support base of the mechanism is moved away from the upper edge of the dumped tier. This makes it possible to form high dump tiers with a corresponding reduction in the area of new routes, and the monitored fan dumping of rock enables to level the surface and select the appropriate rock for the surface layer, with reduction in the cost of reclamation and road construction by this method; at the same time, higher safety of dumping operations.

EFFECT: simplification of dumping process due to increase in height of dumped tier and increase in width of dumping entry, reducing the volume of planning and road works and increasing the efficiency of stripping excavators of the pit due to regular supply of vehicles.
