Abstract
A method for formation of borehole charge with explosive that includes installation of initiation means in the well, placement of explosive charge in the borehole with formation of cavity between the explosive charge and hole wall filled with inert material and stemming. Surface of the explosive charge turned to free surface of the hole wall has rigid coating. Cross section of the explosive charge and form of surface turned to free hole wall are determined according to conditions of blast operations at which area of cross section of the explosive charge is not larger than 4.5/5 of area of cross section of the borehole.
