Abstract
The complex of measures for increasing the time of explosion impact on the rock mass is analyzed. The results of experimental explosions with different types of boreholes are given. It is revealed that the use of a special locking baffle together with the formation of air gaps inside the charge and under the baffle improves the quality of crushing with a simultaneous reduction in the consumption of explosives.
