| Abstract: | Wavelet analysis is a better tool to do time-frequency analysis than Fourier analysis, and it has a very good time-frequency decomposition effect. The C3 coherence cube is a new seismic attribute, which has higher underground structural resolution than normal amplitude cube. In this paper, by combining wavelet analysis with C3 coherence cube, a good result is obtained in identifying small scale structural anomalies especially in small faults in coal mines. |
