Abstract: Through analyzing the empirical formula for predicting the blasting quality peak velocity and the measured data of some mine,two key factors for influencing the blasting vibration velocity are determined,that is,the maximum charge in one delay time and the distance from blasting center.Based on this,the multivariate linear regression model is established,and the attenuation regular of blasting vibration velocity is obtained with the SPSS software.

Key words: Blasting vibration velocity, Multiple linear regression model, SPSS software, Attenuation regular
