Effect of Initiation Location within Blasthole on Blast Vibration Field and Its Mechanism

Figure 4

Illustration of the phase delay effect of the charge elements. (a) Computation model of the blast stress field of cylindrical charge. (b) Normalized peak stress at the same distance from the charge center O, and the peak stress is represented by the normalized distance from O in the polar coordinate system.
