TUNNELLING EXPLODING-LOADING COMPLEX Russian patent published in 2012 - IPC E21D9/10 E21C27/20 E21D9/12 E21D13/04 

FIELD: mining.

SUBSTANCE: complex comprises a receiving wedge part with a loading module, a hopper for exploding and loading, an unloading scraper part, a self-movement mechanism, a pump station, a control panel, a hydraulic manipulator with a drilling machine on a portal trolley moving along a loader column, a safety support moving along guides at hopper boards with the help of sliding carriages. At the same time the inner part of guides at boards of the hopper for exploding and loading is arranged in the form of a geared rack, and wheels of sliding carriages of the safety support - in the form of geared wheels moving along the rack, besides, movement to geared wheels is transferred from electric drives installed inside sliding carriages, and their supply is provided by electric cables wound onto drums installed in a tail part of the hopper for exploding and loading and having a mechanism of automatic winding making it possible to pull a cable from a drum as sliding carriages move along the hopper to the bottomhole, and to wind the cable back onto the drum as sliding carriages move away from the bottomhole.
