摘　　要：以萨道夫斯基爆破振动速度计算公式为基础,结合岩石损伤理论和岩石爆破破碎机理,从理论上研究和探讨煤矿井下微差爆破振动速度衰变规律,推导出了理论计算公式,并通过现场煤矿井下岩石巷道掘进爆破振动实测数据进行了验证,两者基本一致。Based on the Sodcv＇s empirical formula of blasting vibration velocity and the theories of rock damage and rock blasting breaking, the decay regularity of-millisecond blasting vibration velocity in coal mining was studied and discussed. The theoretic calculation formula was deduced. The value of theoretical calculation keeps good consistence with the actual data of vibration velocity in tunneling blasting of coal mining, which indicates the theoretic calculation formula is valid.
