<p>The device (1) has a detonation chamber (3) deposited with explosive substances to be removed/blasted. The chamber includes a cylindrical shell (5), which is made of a wound material such as wound sheet e.g. sheet coil. Front parts (4, 4') are displaceably arranged at both-sided shell ends of the chamber, and act as counter bearings. The front parts receive detonation energy in an axial direction relative to the chamber during detonation of the deposited explosive substances. The front parts are designed as containers (8, 8') filled with ballast substance e.g. sand.</p> |
