Abstract: 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.
