Controlled electromagnetic induction detonation system for initiation of a detonatable material
First Claim
1. A controlled electromagnetic induction detonation system for initiating a detonatable material, the system including:
- an automated radio charge (ARCH) module for delivering an electric detonation current to a detonatable material, said ARCH module including a power circuit for extracting power by means of electromagnetic induction from a electromagnetic field generated remotely from the ARCH module, the power circuit providing operational power for the ARCH module and the electric detonation current, and means for receiving and decoding radio transmitted control signals including a FIRE code, the verified receipt of which causes the ARCH module to deliver said current to and thereby initiate the detonatable material.

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)].

18. A controlled electromagnetic induction detonation system for decoupled in hole initiation of an energetic substance, said system including:
-
an automated radio charge (ARCH) module coupled to an energetic substance and deposited in a hole formed in a hard material, the ARCH module having a power circuit for extracting by means of electromagnetic induction operational power from a remotely generated electromagnetic field, the power circuit providing operational power for the ARCH module and arranged to generate a detonation current deliverable to the energetic material, and means for receiving and decoding radio transmitted control signals including a FIRE code, the verified receipt of which causes delivery of the detonation current to the energetic material;
