Abstract
An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a radio frequency identification (RFID) based switching device that detects a switching property of a radio switching signal that is transmitted to the detonator system and switches the initiating device, on detection of the detonation initiating property, to a standby condition in which the initiating device is capable of operatively accepting the detonation initiating signal when it is transmitted thereto.
