Publication number: 20150369573Abstract: An explosives detonator system includes a detonator housing within which is provided a detonation circuit that includes a conductive pathway having a fuse head integrated therewith such that the conductive pathway passes along both electrodes and a resistive bridge of the fuse head. An uncharged chargeable voltage source is also integrated with the detonation circuit and is electrically sensitive to a charging property which is included in a charging signal. Exposure to the charging property charges the voltage source, thereby rendering it capable of generating a potential difference between the electrodes at least to equal the breakdown voltage of the resistive bridge. The charging property is any one or more of a charging light pulse, a charging temperature, a charging pressure and a charging radio frequency.Type: ApplicationFiled: August 31, 2015Publication date: December 24, 2015Applicant: AEL Mining Services LimitedInventors: Elmar Muller, Pieter Stephanus Jacobus Halliday, Clifford Gordon Morgan, Paul Dastoor, Warwick Belcher, Xiaojing Zhou, Glenn Bryant

Patent number: 9091520Abstract: 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.Type: GrantFiled: December 9, 2011Date of Patent: July 28, 2015Assignee: AEL MINING SERVICES LIMITEDInventors: Elmar Muller, Pieter Stephanus Jacobus Halliday, Clifford Gordon Morgan, Paul Dastoor, Warwick Belcher, Xiaojing Zhou, Glenn Bryant
