Zusammenfassung:This invention relates to mining industry. A borehole charge comprises explosive substance placed to the well, axial cavity formed in the explosive substance, intermediate detonator. In the length of the borehole charge in turns charges of explosive substance are formed, with axial cavity and continuous ones, at that the length of the charge with axial cavity is not less than 1/3 of the length of the next continuous charge. This invention makes it possible to increase effectiveness of destructive effect of the borehole charge.
