Abstract

The data of the uniaxial compression tests of limestone samples with the registration of the strain gauge data and parameters of acoustic emission and thermoradiation signals are presented. A joint analysis of the experimental time dependencies of the variations of mechanical and physical parameters is performed. The identification methods of the deformation stages of the test samples are considered, and the possibility of the integrated use of acoustic and thermal measurements in monitoring systems for geomechanical events in rock masses is presented.
