摘　　要：地表塌陷、沉降、滑坡、矿山开采引起的爆破等非天然事件有时会带来严重的社会危害,需要开展更多的研究,积累应对处置的方法与经验。本文收集整理山西数字地震台网2004-2020年记录到的矿山爆破、核爆破、工业爆破等波形资料,开展对波形特征的研究,并对各个类型的爆破当量进行估算。为今后准确识别爆破震动提供参考依据,同时也为测震台网非天然地震的准确速报提供借鉴经验。Non-natural events such as surface subsidence,subsidence,landslide,and blasting caused by mining can sometimes cause serious social harm.More research is needed to accumulate methods and experience for handling.This paper collects and collates the waveform data of mine blasting,nuclear blasting,industrial blasting,etc.recorded by Shanxi Digital Seismological Network from2004 to 2020,studies the waveform characteristics,and estimates the blasting equivalent of each type.It provides a reference basis for accurate identification of blasting vibration in the future,and also provides reference experience for accurate and quick report of non-natural earthquakes in the seismic network.
