METHOD AND DEVICE FOR ROCK TRANSPORTATION FROM PIT

摘要

FIELD: mining industry, particularly open cast mining. ^ SUBSTANCE: method involves loading tanks at lower horizon during tank unloading at upper horizon and lowering empty tanks from upper horizon during loaded tank lifting from lower horizon; providing additional sites for tank loading at lower horizon and corresponding additional sites for tank unloading at upper horizon; laying cable in zigzag manner so that the cable passes along loading and unloading sites and creates pulling branches; connecting tank with aerostat to each pulling branch. Tanks located at upper and lower horizons are fastened to next nearest branch so that distances between loading and unloading sited along the branches are equal one to another. Device for above method realization is also disclosed. ^ EFFECT: increased capacity. ^ 2 cl, 2 dwg
