DETONATING SYSTEM FOR INITIATION OF DETONATING MATERIAL Russian patent published in 2002 - IPC

FIELD: detonating system controlled with the aid of electromagnetic induction for initiation of detonating material, in particular, but not exceptionally, for contactless initiation of detonating material in a blast-hole. SUBSTANCE: detonating system has an automated rapid-controlled charging module (ARCH-module), connected to an energy matter and placed in a blast-hole formed in solid material, the ARCH-module is made without own steady power source and contains a power circuit for production of operating power from a remote-induced electromagnetic field with the aid of a means of electromagnetic induction, and the power circuit is made for provision of operating power for the ARCH-module and has a structure made for generation of detonating current applied to the energy material, and a means for reception and decoding of radio-transmitted control signals, the FIRE code inclusive, at whose verified reception the detonating current is applied to the energy material. The detonating system has also a tamping stick for tamping the charge into the hole, accommodating the energy material and the ARCH-module and the converter unit for radio transmission of control signals, having a winding for inducing the electromagnetic field installed on/or in the tamping stick for provision of transmission of operating power to the ARCH-module by means of electromagnetic induction. EFFECT: reduced probability of random initiation of the detonating material. 33 cl, 11 dwg
