FIELD: devices used for blasting, applicable for initiation of explosive charges, as well as a source of excitation of elastic vibrations at seismic prospecting. SUBSTANCE: cylindrical casing accommodates an explosive charge, explosive POROTOL is used for the purpose. The charge is formed by the filling-in method with formation of a through axial channel and a blind channel parallel-shifted relative to the latter, which are interconnected by a groove, made with a rounding-off radius of at least 6 mm and at least 15 mm deep.
