The behavior of rock workings at deep levels of Donbass mines during drilling and blasting operations is related to critical dynamic phenomena of rock pressure. With the aim of establishing the correlation between explosive pulse parameters and potential elastic energy for rocks during failure, the problem was set for determining the critical value of loading occurring during explosion of a blast-hole charge and the satisfactory condition of developing the failure process in a quasistatic approximation not leading to critical dynamic phenomena.
