| 摘 要： | 采用Matlab的小波变换方法,对山西省数字化台网记录的爆破、塌陷与地震信号进行了6层多尺度分解,通过比较、分析,得出爆破、塌陷与地震信号在各层分解后存在一定的差异,该研究为识别非天然地震中的爆破、塌陷提供了有效的方法。

| Abstract: | By using wavelet transform provided in Matlab,blasting,collapse and seismic signals recorded in Shanxi digital seismic network are decomposed into 6grades in multi-scale.It is concluded that some differences exist among blasting,collapse and seismic signals at various grades of decomposition,which would be an effective method to identify artificial earthquakes such as blasting and collapse. |
