With extensive application of blast techniques, more and more attentions are focused on the influence of blast vibration. 随着爆破技术的广泛应用,人们越来越关注爆破震动,爆破震动危害己成为国民经济建设中一个重要的环保问题。
With the coefficient the paper discussed the safety assessment of the regression formula for predicting the blasting vibration. 用安全系数对回归公式预报爆破震动强度的安全性进行评估。
