FIELD: blasting, applicable for filling of boreholes with charge components at opencast mining. SUBSTANCE: for mechanized charging of vertical boreholes with powder charges with an axial duct in the blasting cartridge a slot is cut through the entire thickness of the burning arch, whose width freely passes a rope. Blasting cartridges are strung on the rope with a bearing disk, lowering them in the borehole on the rope reeled off the drum. On completing the assembly of the charge combined with its lowering in the borehole to the preset mass, the whole charge is lowered to the borehole face, freeing the charge from the rope, disengaging it from the bearing disk and cutting off the rope in the borehole mouth. EFFECT: enhanced safety of filling of boreholes with blasting cartridges of ballistite powders. 5 dwg
