Abstract: 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.

Key words: fine analysis, regression calculation, vibration velocity atlas
