Abstract
In given work was considered an impulse’s formation process of extended charge explosive with installation a continuous and a special stemming in the hole. Was given the physical model to definite a size of the reflected wave impulse. Also was taken into account an increment radius of cross-section blast hole and expirations of detonation products. Was developed the model consists gas dynamic process in the hole during changing the central canal of the stemming.
