周期-频度谱在小爆破自动识别研究中的应用
The automatic discrimination and criteria study between blasts and small earthquakes by analysis of period-spectrum
【摘要】 历年来在所开展小爆破识别与判据研究的基础上,进行了计算机易于实现爆炸事件自动识别判据的研究,通过对近震、爆破、矿塌和远震事件的周期-频度谱、波形不规则指数、卓越周期开展的研究,确定了切实可行的爆破事件自动识别方法和判据,达到了77%以上的正确自动识别概率。关键词爆破;自动识别;周期-频度谱;波形不规则指数;卓越周期
【Abstract】 Based on the studies we have done before about the discrimination and criteria between blasts and small earthquakes, we do some researches on the automatic discrimination and criteria obtained from period-spectrum analysis. We also give the criteria of waveform irregular index and predominant period to discriminate blasts automatically, and the discrimination probability reaches 77%.
