An explosive package is provided for use in seismic exploration which comprises a seismic charge and an addressable switch for selecting that seismic charge for detonation. A fireset is operatively coupled to the addressable switch for receiving a firing voltage via the addressable switch and for producing an actuation voltage. The actuation voltage may, for example be produced by increasing the magnitude of the firing voltage. The actuation voltage is provided to a Detonating Device, which is a device that contains secondary explosives. Examples of a Detonating Device include an exploding bridge wire detonator, an exploding foil initiator detonator and a semiconductor bridge slapper device. Such explosive packages may be arranged in a system for use in seismic exploration which comprises a base unit for providing selection, firing and trigger signals and a plurality of explosive packages that are located at spaced intervals along the earth's surface. |
