Abstract
The controlled electromagnetic induction detonation system for initiation of a detonatable material system [(10)] includes an automated radio charge (ARCH) module connectable to an electric detonator [(24)], a transducer module [(14)] for providing operational power by electromagnetic induction to the ARCH module [(18)], and a remote controller [(12)] for sending instructions to the transducer module [(14)] from a location remote from the detonator [(24)]. Upon completion of an arming sequence, the transducer module [(14)] generates an electromagnetic field which is picked up by a coil in the ARCH module [(18)] and used to power the ARCH module [(18)] and provide a detonation current for the detonator [(24)]. The transducer module [(14)] or at least a coil thereof which produces the electromagnetic field is supported on or in a stemming bar [(16)] which in turn acts as a core of an electromagnet confining the magnetic flux for pick up by the ARCH module [(18)]. Multilevel access control and interlock systems operate between the remote controller [(12)], transducer unit [(14)] and the ARCH module [(18)] to reduce the likelihood of unintentional initiation of the detonator [(24)].
