Zusammenfassung:The possibilities of controlling the edge effect of the explosion of the conic primer in the lower part of the borehole charge on the level of the bench sole are considered. The data from the analytical studies of the formation of the strain field in the corner area of the borehole bottom are shown. The feasibility and efficiency of using an intermediate detonator (cone-shaped primer) at the lower end of the borehole charge to reduce the depth of the subdrilling are confirmed.
