摘要
利用山东省枣庄市陶庄煤矿区鲁15井水位观测资料,采用多道Weiner滤波方法研究其中所隐含的孕震信息,结论是没有明显的矿震中期前兆异常,临震前兆异常明显,每次矿震前都有水位的短临变化。
Underground mining earthquakes are induced by mining activities.The formation of mining-induced earthquakes and that of natural earthquakes have some similarities.Weiner filtering approach is used to find out the earthquake information.Results show there is no obvious precursor anomaly,but obvious impending precursor anomaly,and the water level changes in the time of mining-induced earthquakes.
