Abstract :
The paper discusses results of the laboratory loading of rock samples and synchronous recording of the electromagnetic emission and load rate. It is shown that appearance of low frequency components in the structure of the electromagnetic emission signals at the first stages of loading can be the sign of a discontinuity.
