Abstract: On the basis of probabilistic model of time of initiation of borehole charges analyzed not electric system of initiation It is shown that when using not electric system of initiation which is characterized by dispersion of time of operation of delay mechanisms concerning the face values, distribution of borehole charges on groups of simultaneity has casual character. The maximum quantity of the borehole charges getting to one group at standard schemes of installation of an explosive network is statistically steady and depends mainly on the applied face values of delay and quantity of longitudinal ranks of wells. From the first steps of delay of NESI substantially ceases to carry out function of the regulator of the short-delay detonation providing quality of crushing of mountain weight and carries out only function of increase in the general duration of explosion. Thus the number of the charges which are blowing up before the established turn reaches 20%.
