FIELD: mining.
SUBSTANCE: system includes bottom-hole, dumped and intermediate running fixed platforms connected by means of two running lines, two-sided bucket with V-bottom connected to each mast by means of hoisting-hauling line enveloping the corresponding sheave arranged between running lines with possibility of movement relative to each other together with running lines. Intermediate running fixed platform is equipped with two supporting sheaves of running lines and one supporting sheave of hoisting-hauling lines. Rotation axis of hoisting-hauling line sheave has the possibility of being moved along guide curves of running lines.
EFFECT: improving efficiency, reducing the wear of lines and improving environmental conditions owing to equipping the mast of intermediate running fixed platform with the most effective equipment.
