Apparatus for breaking rock which includes a first cartridge (30) with a base (32) and a side wall (34) which form an enclosure, and a propellant (42) inside the enclosure, and wherein a discontinuous relatively weaker region (60) of the container is formed at a junction between the wall and the base.
L'invention concerne un dispositif pour briser la roche, comprenant une première cartouche (30) pourvue d'une base (32) et d'une paroi latérale (34) formant une enveloppe, contenant un agent propulseur (42). L'enveloppe comprend une zone (60) légèrement plus faible, discontinue, située au niveau de la jonction entre la paroi latérale (34) et la base (32). Cette caractéristique permet de diriger la substance sous pression contenue dans l'enveloppe vers le pourtour de la base, lors de l'explosion, et de provoquer la rupture de la roche située à proximité dudit pourtour de la base.
