No matter what type of delay priming circuit is adopted, the number of delay electric detonators is large, the number of delay sections is large, and therefore higher requirements are provided for the shock resistance of the electric delay detonators in the blasting network. Due to the impact of the detonation wave during blasting, each explosion point can bring strong impact and overpressure to the adjacent explosion points which are not exploded yet at the moment of explosion.
