Abstract

There exist 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 defects of traditional Sadaovsk formula, a modified Sadaovsk formula (MSF) considering the height deviation between mass point and blast center was introduced. A multiple linear mathematical model for predicting the attenuation law of blasting vibration was established. The unknown parameter vectors(K, α, β) in the model were calculated by using least square method, thus the concrete MSF for accurately predicting the attenuation law of blasting vibration was achieved. The single-hole blasting vibration of the zinc-copper deposit in Tongkeng Mine was monitored and the data were analysed by using the proposed method. The results show that the proposed MSF is reliable, and can provide scientific guide for blasting design in zinc-copper deposit.
