Based on biaxial shear creep tests conducted on rock samples with different water contents, we present the results of our
study on the regularities of electromagnetic and acoustic emission during the process of creep experiments in which we have analyzed
the contribution of water to the occurrence of electromagnetic radiation. The result shows that in the creep-fracturing course
of rock samples, when the water content increases, the initial frequency and amplitude of electromagnetic and acoustic emission
also increases, but at a decreasing growth rate caused by loading stress. This can be used as a criterion for the long-term stability of
rock masses under conditions of repeated inundation and discharge of water.
