Abstract

In the technical literature, it is widely accepted that crushing of rock during explosion is carried out by stress waves, that only 1-5% of the energy of stress waves is spent on crushing. When exploding an explosive charge in a rock, the nature of energy transfer to the external environment depends on the properties of the explosive, charge density, the geometry of the charge and its position in the massif.
