Abstract：There exists complicated non-linear relations between explosive vibration effect and its affecting factors, and accurate prediction of the attenuation law of blasting vibration is the basis of blasting design and disaster control. Based on the analysis of the defects of traditional Sadaovsk Formula, Modified Sadaovsk Formula(MSF) considering the height deviation between particle and blast center is introduced. At the same time, multiple linear mathematical model for predicting the attenuation law of blasting vibration is established. And then the unknown parameter vectors(K, α ,β) in the model are calculated using least square method, thus obtains the concrete MSF for accurately predicting the attenuation law of blasting vibration. Eventually, analyzes the monitoring results of single-hole blasting vibration of zinc-copper deposit in Tongkeng Mine using the proposed method. The results show that the proposed MSF is reliable, meanwhile, the expression and significance of parameters in MSF coincides with practical situation, and can provides scientific direction for blasting design in zinc-copper deposit.
