FIELD: blasting operations.
SUBSTANCE: device comprises an explosive charge of cylindrical shape, an axisymmetric element of polymeric material located on one of its ends, which is provided with an axial cumulative recess in the form of hemisphere-cylinder at its outer end. The cumulative recess is covered with metal cladding of different thickness. There is also a device of initiation located at the end of the charge, opposite the end with the axisymmetric element, or side surface of the charge and made with the annular location of initiation points. On the end of the axisymmetric element adjacent to the charge, an axial protrusion is made, and the charge in this case is provided with a recess corresponding to the said protrusion.
EFFECT: obtaining high-speed compact elements with the required speed.
