Abstract

L'invention concerne un système de forage (10) de puits (1) à l'explosif (10). Selon ce système, les forages sont effectués en différents niveaux successifs (12, 13), pour chacun desquels sont prévues plusieurs charges (16). A chaque niveau correspond un commutateur adressable (14) qui, en position de repos, branche le circuit d'allumage (11) et, en position de travail, sépare ledit circuit d'allumage pour le raccorder à un dispositif de commande d'allumage (15) pour le niveau de forage correspondant.
