A control system for controlling the initia-tion of detonation of a series of explosive charges (13) spaced apart from each other in boreholes (12) formed in a rock medium (10) to be blasted, said system being operative to apply controlled time difference in the time interval between suc-cessive detonations of at least one phase of the se-ries of charges, and which includes at least three successive detonations, so as to reduce the proba-bility of consecutive stimulation and amplification of ground vibration by reason of the detonation of the charges in the rock medium.
