Summary:Title screen
Physical modeling in vitro is a way to carry out basic laws of mechanoelectric transformations in a rock massive. In this paper we examined how rock mechanical properties influenced on parameters of electromagnetic signals (EMS) excited by the determined acoustic impulse under uniaxial compression. It has been determined that sulphides and quartz in rock samples from the Tashtagolsky iron-ore deposit (Western Siberia, Russia) promote transformation of a mechanical energy to an electromagnetic field energy which is expressed in an augmentation of an EMS voltage. An EMS voltage reduction at the change of the stress-strained state of the sample in the course of an uniaxial compression is observed with quantity augmentation of containing of high-conducting magnetite in rocks. The obtained results are important for a physical substantiation of the method of monitoring of the stress-strained state of rock massive by mechanoelectric transformation characteristics.
