In order to analyze the attenuation law of blasting vibration wave through the damping groove, and to explore the function relations between the damping groove depth and damping effect of affiliation; the discussion about the blast hole millisecond firing initiation technique is based on the numerical simulation analysis software ANSYS / LS-DYNA; in the process of explosion, vibration wave of blasting through the damping groove attenuation in a plurality of rows of holes is researched; and get the membership function by MATLAB simulation. The engineering blasting damping ditch used in breaking for verifying the rationality. By comparing simulated and real results, when the damping groove depth is 1.2 times the depth of the hole, the damping effect is the best.
