METHOD FOR MODIFICATION OF PIT RESERVES WITH A HIGH VERTICAL LEDGE Russian patent published in 2019 - IPC E21C41/26 E21C47/02 B65B1/30 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used for development of pit reserves limited in terms of steeply falling deposits of solid minerals. Method includes production of rock by means of continuous extraction process with development of mineral by mining complex by layer-strip method, periodic supply of rock mass into soft containers through hopper, delivery of soft containers from face surface to intermediate horizon of pit by cable system with lifting mechanism. Development of reserves is carried out remotely by means of automated control system with sensors of control. Cartridges with soft containers are supplied by means of lifting mechanism to the platform of production complex. Turning device of lifting mechanism positions gripping device with cartridge at angle of orientation of mining complex. Cassette is lowered to the platform and moved to the working position to ensure continuous supply of soft containers during operation of the production complex. Lifting mechanism with gripper moves into zone of soft container with rock mass and is positioned by rotary device of lifting mechanism to grip and move soft container to intermediate pit horizon.

EFFECT: higher efficiency, safety of mining operations, reliability, expansion of technological efficiency and reduction of environmental load on environment in area of mining operations by providing remote control of operation of production complex.
