摘    要:根据辽宁数字地震台网记录的爆破、矿震与地震的数字资料,采用波谱分析的方法,选取4个台站对其所在区域182个爆破、矿震与地震事件的记录,对比研究波谱特征,发现爆破、矿震与地震的纵横波拐角频率fc(P,S)及最大谱值等存在的差异。

关 键 词:波谱  拐角频率  爆破  矿震  地震

Abstract:Based on the 182 digital data of explosion,mine tremor and earthquake recorded by Liaoning Digital Seismic Network in the nearby area of 4 stations.We had studied and compared the characteristics of wave spectrum of these events and found that the corner frequency and the maximum spectrum are different for explosion,mine tremor and earthquake.
Keywords:wave spectrum  corner frequency  explosion  mine tremor  earthquake
