摘要：

The results of hardware and methodological developments for recording of electromagnetic emission (EME) generated by rock samples under loading in laboratory experiments are presented. The results of experiments with the instruments developed are described. The facilities developed made it possible to measure reliably the electromagnetic emission under conditions of high background of electromagnetic noise and to reduce the level of reliably recorded signals as compared with previous experiments. The results of observation of the appearance of electromagnetic emission in the experiments with the rock samples under laboratory conditions showed a high correlation of the time instants of generation of the electromagnetic emission and the changes of its parameters with the changes in the reactive resistivity of the rock sample and seismoacoustic emission activity in the controlled area of the sample. It is revealed that electromagnetic emission occurs and reaches its maximum on the descending branch of the plot of polarizability during rock destruction.
