The seismic channel integration is a nonrestrictive inverse technique using seismic data, i.e., a technique for stratigraphic analysis based on the relative velocity of the strata obtained by seismic channel integration. The application of seismic channel integration to the recognition of the coal seam missing and thinning zone shows that the small-sized coal seam missing and thinning zone basically has no demonstration in the 3D seismic time profile, and that the anomaly of the relative wave impedance can be effectively recognized in the seismic channel integration time profile. Thus the coal seam missing and thinning zone can be interpreted. The interpretation result is consistent with the edit exposure, suggesting that the seismic channel integration is an effective and practical technique for seismic interpretation.
