摘要
总结了人工爆破与天然地震的区别和记录特征。在对模拟遥测地震台网直观、定性判定爆破的基础上提出结合用S波与P波的振幅比值(As/Ap)和视速度V这两项量化指标进行定性与定量相结合判别。并按照这一思路成功判定了在2004年4月至5月中的一次密集人工爆破群。
The wave recording characteristics and the distinction of both earthquakes and explosions recorded in Xichang telemeter seismic network are summarized.Based on the following three aspects:visual judging on the recording of wave,the amplitude ratio(v_s/v_p)of S-wave to P-wave vibration and velocity v of seismic wave,we distinguish a series of artificial explosion swarms occurred in mines from natural earthquake swarms in Xichang region.
