爆破振动速度衰减规律的多元线性回归分析

Multiple Regression Linear Analysis on Attenuation Formula of Blasting Vibration Velocity

通过分析爆破质量峰值速度常用预测经验公式和某矿山实测数据,确定了影响爆破振动速度的两个关键因素是单段最大起爆药量和爆心距,并由此建立了多元线性回归模型,通过SPSS软件进行多元线性回归分析得出爆破震动速度衰减规律。

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.
