Abstract
The article studies dependences of rock strengths on the time of their stressing basing on the thermal-kinetic theory of strength. The main task of the research was to calculate thermo-kinetic features of rocks and, taking into account cleavage data, to build up calculation dependences and compare them with experimental results. As the result, indices of dynamic tensile (pull) and shear strengths have been received, which are necessary for subsequent calculation of parameters of drilling and blasting operations.
