FIELD: oil and gas industry. ^ SUBSTANCE: method for forming hose charge in wells involves well drilling, arrangement of hose charge in it and stemming by means of inert materials. At that, hose charge is made in the form of a spiral wound on thin-wall perforated plastic pipe, with winding pitch equal to 4.0Ç5.0 diameters of hose charge. Hose charge and detonating cord is attached to thin-wall perforated plastic pipe. After the assembled structure is arranged in the well, cavity of the pipe and gaps between coils of hose charge are filled with water to the level of hose charge and the well is stemmed with inert materials. ^ EFFECT: reducing the specific flow of an explosive, increasing the crushing efficiency of rock masses, and reducing the dust loading of ambient air. ^ 1 dwg |
