| 摘 要： | 主要研究小当量爆破(即矿山爆破)与小震级地震事件的识别与判据。我们利用北京遥测地震台网的短周期模拟记录资料作过一些研究(傅等,1997),取得了一定的进展,在此基础上,又利用北京遥测地震台网的DAPS(模拟信号台网中心数字化地震记录)系统进行了较为深入、定量的研究。主要根据两者在波形记录特征、ML与MD震级差别、频谱分析中卓越周期与拐角频率方面的不同,使得地震与爆破的识别取得了较高的概率。

| Abstract: | We discuss the discrimination and criteria between blasts and small earthquakes in this paper. Based on those concerned items we have done before with analogue data of BSTN, this time we use the data from DAPS (Data Acquisition and Processing System,A/D at network centre) to analyze the characteristic of waveform, M_L and M_D, predominant period and corner frequency of blasts and small earthquakes. The results suggest the higher discrimination probability. |

| Keywords: | blast small earthquake discrimination waveform characteristic difference of M_L and M_D predominant period corner frequency |
