SEISMIC BLASTING SYSTEM Russian patent published in 2012 - IPC G01V1/104 

FIELD: blasting operations.

SUBSTANCE: invention refers to blasting system for seismic charges which are protected against detonation hazard by means of radio-frequency signal (RF) and electrostatic discharge (ESD). Seismic blasting module, system which is used during seismic exploration, as well as seismic exploration method is proposed. Seismic blasting module is intended to be used during seismic exploration; at that, it is required to use selection signal, starting signal and initiating signal for detonation; at that, all the above signals have been received from base module, and the above seismic module includes the following: seismic charge, addressable key which receives selection signal for selection of seismic charge for detonation, ignition device, which when in working state is connected to addressable key to receive starting signal, and which is responsible for formation of actuation voltage at the output, and detonation device which when in working state is connected to outlet of ignition device; at that, detonation device is responsible for initiating signal for detonation of seismic charge at supply of actuation voltage to detonation device. System which is used during seismic exploration includes the following: multiple seismic blasting modules each of which has addressable key provided with a unique address and base module which is intended to supply the appropriate selection signal, starting signal and initiating signal to seismic module. Seismic exploration method using the system consists in uniform distribution of blasting seismic modules on surface of the area above which it is required to perform seismic exploration; and detonation of each individual module as per the appropriate first selection signal, starting signal and initiating signal from base module.

EFFECT: safer transportation and storage of blasting module together with its initiation schemes, protection of the system against accidental initiation of explosion determined with usually occurring random voltages, currents, electrostatic discharge and simply mistakes made by people.
