3D forward modeling and seismic attribute sensitivity test of collapsed column

According to the technical difficulties of high resolution detection technology for coalfield collapse column, the paper conducted forward numeric modeling of one-way seismic wave by using four seismic models for collapsed column of irregular shape, different height and different filling materials (including the loose filling and the air filling) and with major axis of 80m, 50m, 25m and 15m. 50, seismic attributes including amplitude, energy, frequency, waveform, variance and coherence were extracted. 18 sensitive attributes including amplitude, energy, time intervals and variance and coherent were selected visually. Similarity analysis was carried out among 18 sensitive attributes and original geological profile using image analysis, then the sensitivity of the 18 attributes was sorted. All these will provide a theoretical basis for collapsed column interpretation.
