Abstract:
A wireless detonator (10) includes a detonation side receiving antenna (11), a detonation side transmitting antenna (18), an initiator (14) and a detonation side electronic circuit. The detonation side receiving antenna (11) receives energy for driving the detonation side electronic circuit, a control signal and an initiation signal. The detonation side electronic circuit receives the energy, the control signal and the initiation signal via the detonation side receiving antenna (11), transmits a response signal via the detonation side transmitting antenna (18) and ignites the initiator (14) in accordance with the initiation signal. A response frequency of the response signal is set to be greater than or equal to 100 MHz and less than or equal to 1 GHz.
