Abstract

The physical basis of most known methods of explosion control is the dependence of mechanical behavior of rocks (deformation, fracture) on the time characteristics of the loading mode. However, using this dependence, we usually do not take into account its relaxation nature, which is characteristic of the entire class of geophysical media, actively affecting changes in their physical state, determining the dissipation of energy of force impact and, consequently, affecting its result. Therefore, the study of the relaxation properties of rocks has been given increased attention.
