对某现场爆破振动地表振动速度峰值监测结果进行了研究，拟合得到了地下工程岩石开挖爆破地面振动速度的变化规律，并对同断面、同药量、同测点掏槽爆破地表质点振速和非掏槽地表质点爆破振速进行比较，结果表明掏槽爆破产生振速较大，合理设计掏槽为关键点。
對某現場爆破振動地錶振動速度峰值鑑測結果進行瞭研究，擬閤得到瞭地下工程巖石開挖爆破地麵振動速度的變化規律，併對同斷麵、同藥量、同測點掏槽爆破地錶質點振速和非掏槽地錶質點爆破振速進行比較，結果錶明掏槽爆破產生振速較大，閤理設計掏槽為關鍵點。

We got the variation law of ground vibration velocity in underground rock blasting excavation which based on fitting the monitoring re-sults of ground vibration velocity peak of blasting vibration in the scene. By comparing the surface particle vibration velocity between cut blasting and non in the same section,explosive charges and test point. The results show that the reasonable design of cutting technology is the key point as cut blasting generates a larger vibration velocity.
