摘　　要：运用湖南某矿的地下爆破振动监测采集的三矢量数据进行地震波破坏程度的描述。以振动速度三个分量中最大的一个判据为准,运用线性回归分析,得到爆破振动回归公式。通过回归公式及三矢量数据即可反映该矿山爆破地震波的传播衰减规律,又可对该矿山以后的爆破作业提供理论参考和指导。Through monitoring a lot of triple vector data of underground blasting vibration in one mine in Hunan province,the destructive extent of seismic waves could be described in this paper.According to the biggest one of three components,the forecast formula of blasting vibration velocity could be obtained by regression analysis.The formula and triple vector data not only could reflect the travel law of blasting seismic wave of this mine,but also could offer a theoretical reference and guidance for the blasting work in future.

关 键 词：爆破地震 振动监测 三矢量 回归分析
