Abstract

Ce système, dans lequel chaque détontateur 9 est constitué par une cartouche 10 contenant une charge d'inflammation 13 et munie d'un ou plusieurs conduits 14 qui débouchent sur l'extérieur, est caractérisé en ce qu'il comporte des moyens 17 à 38, placés à l'extérieur des cartouches pour évacuer hors des détonateurs le gaz non explosif qui s'y trouve et le remplacer par un mélange gazeux explosif, ainsi que pour enflammer ledit mélange lorsqu'il se trouve en position de détonation dans les cartouches. L'évacuation du gaz non explosif peut s'effectuer, soit en appliquant le vide au système ferme, préalablement à la mise en place du mélange explosif, soit en augmentant le volume du système et en utilisant la pression du mélange explosif pour refouler le gaz non explosif dans le volume supplémentaire créé.
