Applying reiterative method, this Paper simulates the blasting stress field of cylindricalcharge, and then, gets attenuation law stress peak value and characteristics of stress distribution.
In the paper, experiments in testing blast strain waves, generated from the explosion of some small cylindricalcharge, were carried out in rock model using the ultra-dynamic strain testing system.
The empirical unit consumption of explosive under special conditions is considered as a proper blasting strength, from which the calculation formula for the blasting of cylindricalcharge is derived.
