FIELD: blasting operations, applicable in systems for pneumatic extrusion of emulsion explosive to borehole. SUBSTANCE: this system has a vessel for containing of emulsion explosive in it under pressure, source of water under pressure (preferably a vessel for containing of water under pressure), outlet pipe outgoing from the vessel with emulsion, water injector connecting the outlet pipe to the feeding hose and a pipe-line (for example, a hydraulic hose) for feeding water under pressure to the water injector. Feeding of emulsion explosive is effected by pneumatic extrusion from the vessel under pressure. The flow of emulsion explosive is humidified by a circular jet of water that is fed under pressure minimum by 0.7 kg/sq.cm (10 pounds per square inch) higher than the pressure of the emulsion explosive. EFFECT: reduced cost of the system, enhanced safety of work and reduced noise - in service. 6 cl, 1 dwg
