Abstract

The device for producing a wall penetration in tunnel construction uses explosives with an igniting fuse (8) along the complete opening contours. The fuse is in contact with an explosive (7) in a borehole (6) for level explosion. Each borehole can have an exploswive capsule with connection for initiating the charge.
