Kind Code:

A1

Abstract:

A wireless detonator (10) having a detonation-side receiving antenna (11), a detonation-side transmitting antenna (18), a detonation unit (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 a detonation signal. The detonation-side electronic circuit receives the energy, the control signal, and the detonation signal via the detonation-side receiving antenna (11), transmits a reply signal via the detonation-side transmitting antenna (18), and ignites the detonation unit (14) on the basis of the detonation signal.
