Abstract

Un emballage pour explosif est proposé pour utilisation dans une exploration sismique, lequel comprend une charge sismique et un commutateur adressable pour choisir cette charge sismique pour détonation. Un dispositif de mise à feu est couplé de manière opérationnelle au commutateur adressable pour recevoir une tension d'amorçage par le commutateur adressable et pour produire une tension d'actionnement. La tension d'actionnement peut, par exemple, être produite en augmentant l'amplitude de la tension d'amorçage. La tension d'actionnement est transmise à un dispositif de détonation, lequel est un dispositif qui contient des explosifs secondaires. Des exemples d'un dispositif de détonation comprennent un détonateur à fil explosant, un détonateur à initiateur à feuille explosive et un dispositif à percuteur à pont semi-conducteur. De tels emballages pour explosifs peuvent être disposés dans un système pour utilisation dans une exploration sismique qui comprend une unité de base pour procurer des signaux de sélection, d'amorçage et de déclenchement et une pluralité d'emballages pour explosifs qui sont situés à des intervalles espacés le long de la surface de la terre.
