As a rule

to confirm blasting vibration attenuation rule

coefficients of the Sadov’s vibration formula can be regressed with three variables

namely

maximum vibration velocity

maximum charge amount per delay interval

distance between center of blasting area and measurement place. To confirm blasting vibration attenuation rule accurately

coefficients of the Sadovski vibration formula can be gained by use of the unary linear regression theory for per delay consecutive firing

with maximum velocity at different times

corresponding charge amount per delay interval

distance between measurement stationing and hole. A fine analysis method for blasting vibration testing is put forward.
