The invention relates to a packing having a top side, a base side and face sides for hollow charges for use in blasting applications in boreholes. In order that fragments are retained in the packing in the event of an unintentional ignition of the hollow charges, the packing withstands the pressure which is generated and permits a dissipation of pressure, it is proposed according to the invention that a) the hollow charges are embedded in a solid material which captures the fragments generated during a detonation of the hollow charges, b) the solid material has pressure relief openings through which the pressure wave of the gas volume generated during a detonation of the hollow charges can escape, c) the solid material is covered with shock-absorbing material on the top side and on the base side of the packing, d) the hollow charges are packed in pairs such that there are always two hollow charges situated opposite the openings, e) the axes of symmetry of the hollow charges are arranged in a plane perpendicular to the top side and base side, and f) the solid material is inserted with the hollow charges and the shock-absorbing material into a cage, preferably a bar-grate-type cage. |
