3D seismic fine explanation on macro-structure of Coal Seam No.3 of Jining No.2 Mine

The Coal Seam No.3 of Jining No.2 Mine shows on seismic section "thin interbedded" properties due to its branching into Coal Seam No.3 upper and Coal Seam No.3 lower,which caused the accuracy of determing apparent branch point on conventional seismic time section.The application of wavelet analysis technique improved the signal to noise ratio and resolution of original 3D seismic result data body,therefore,the accuraccy of macro-structure explanation of Coal Seam No.3 is apparantly increased.
