- (Contens №2 2020)
- ... Originality. Methodology to evaluate blast-wave parameters within the zone near the borehole or blasthole charge explosion is proposed. Physical mechanism for rock breaking to ultradisperse particles is proposed. It has been specified that thermoelastic stresses may be one of the possible causes, if not the main one, of the rock breaking within the near-explosion zone. A mechanism stipulated by the transition of microstructure of the rock crystalline components to the instable state is considered as the alternative (or additional) factor. The cause is in the oversaturation of the rock microstructure with the linear and point defects. Exceeded value of critical concentration of those defects results in the excessive reserves of internal energy with the following spontaneous breaking of chemical bonds. Impact adiabats of coking coals of three grades as well as isentrope and impact adiabat of the detonation products of emulsion explosive ЕРА Р-3 are constructed. In terms of the “pressure – mass velocity of particles” coordinates, curves of adiabats of the bituminous coals differ by not more than 4 %. ...
