摘　　要：基于中尺度地震实验场高密度数字地震和潮汐形变台网的现场观测,用地震学方法和小波工具分析强矿震过程采集到的数据.发现震前短临阶段存在可信的b值、η值、频度等地震学异常和定点潮汐形变前兆异常.对异常信息的提取方法和强矿震短临阶段的预测进行了探讨.Based on field observations of the high-density digital seismograph and tidal deformation network of a meso-scale seismological experimental site, the data of strong mining-induced earthquake process were analyzed by the seismological method and wavelet tool. Believable b values and η values were tested, and frequency seismological anomalies and fixed point tidal deformation anomalies were found before strong mining-induced earthquake in the short-term and impending stages. The extraction method of anomalous information and the forecast of strong mining-induced earthquake in the short-term and impending stages were discussed.
