Essay

The thesis is devoted to the development of the problem of determining of optimal parameters of explosion technology of rocks destruction in conditions of mine tense and explosives, blast-hole charges of which is detonating in non-ideal regime. The equipment for the researching of the high-speed processes in blast-holes was developed. The non-ideal regime of detonation of mixtured explosives with taking into account the density, the diameter and the sensibilizator quantity in blast-hole charge was researched. The conditions of shock wave following in the gap between blast-hole charges and walls of the blast-hole was researched. The coefficient of blast-hole charging was grounded, where the influence of channel effect is minimal. New mechanism of channel effect influence was proposed. The influence of mine tense on velocity of shock waves in rocks was shown. The critical conditions of detonation transferring between cartridges of explosives was grounded. The influence of time delay between explosions of different blast-hole charges groups on the parameters of explosive works was shown. The effective time delay was grounded. The algorithm of calculation of main parameters of explosive works was developed.
