Spectrum monitoring of electromagnetic signals from rocks to control geodynamic processes under working mine conditions

The paper considers the techniques for continuous monitoring of samples and rocks destruction using the parameters of the measured electromagnetic signals which are generated in the destructive processes. The block diagram of the recorder is presented and the methods for processing of the measured electromagnetic signals to monitor and predict the geodynamic processes in rocks or the destruction of dielectric materials under electromagnetic interference. A phase modeling of the method to extract a useful signal from the background noise and electromagnetic interference has been implemented
