Abstract:
A packaging for hollow charges for use in blasting applications in boreholes retains fragments in the event of unintentional ignition of the hollow charges. The packaging withstands and dissipates the pressure generated. It is proposed that the hollow charges are embedded in a solid material which captures the fragments, the solid material has pressure relief openings through which the pressure generated during a detonation of the hollow charges can escape, the solid material is covered with shock-absorbing material on the top side and on the base side of the packaging, the hollow charges are packed in pairs such that there are always two hollow charges situated with their openings facing each other, the axes of symmetry of the hollow charges are arranged in a plane perpendicular to the top side and base side, and the solid material is inserted with the hollow charges and the shock-absorbing material into a cage.
