FIELD: mining.
SUBSTANCE: invention relates to mining industry. Charger includes horizontally oriented cylindrical chamber 1 with hatch 2, hopper 3, connected through loading opening with cylindrical chamber 1, compressed air pipeline, aerator 5, unloading pipeline 6, charging hose, membrane mechanism 8 with rocker arm 9, four-way distributor 10a and crane installed in front of charging hose. Aerator 5 is made in the form of cylindrical pipe with longitudinal slotted holes 12, is installed with a gap along lower generatrix of cylindrical chamber 1 and is connected through four-way distributor 10a with membrane mechanism 8 and compressed air pipeline. Unloading pipeline 6 is installed along central longitudinal axis of cylindrical chamber 1. At the same time along the total generatrix of unloading pipeline 6 along the whole length slotted hole 13 is made.
EFFECT: simplified design, increased reliability and safety of charging bore pits and wells with granulated explosive substance and increased efficiency and density of loading.
