ABSTRACT:
An apparatus for blasting comprises a series of electronically programmable detonators and an exploder, connected in series. The exploder communicates to the detonators at least programming and firing signals. The detonators are connected in such a way that programming signals will be received by a given detonator only when the adjacent detonator nearer to the signal output of the exploder has been programmed. This is preferably achieved by use of a connector associated with each detonator, the connector comprising a switching device which is operated by a logic element such that the logic element will operate on the switching device and allow signals to pass only when the detonator associated with that connector has been programmed.
The apparatus permits the versatile and precise use of explosives, especially where large numbers of charges are involved.
