A method for formation of well charge of an explosive substance includes substance needed for blast destruction of rocks placed round the axial air channel of the borehole in length of the charge, with elements of initiation in the upper part of the charge. Ammonium nitrate is taken as substance needed for blast destruction of rocks, and as elements for initiation one takes active charge of explosive substance, trotyl block and detonating fuse.
