摘要
At present, thin layer seismic exploration is a hot research topic in seismology, and seismic attributes analysis in thin anisotropic coal seam is a difficult problem to be resolved. In this paper, we do numerical simulation to produce a synthetic seismic record by rotationally staggered grid finite-difference scheme in an anisotropic thin coal beds. Also we illustrate the characteristics from the aspects of snapshot, phase velocity, group velocity when seismic wave propagating in anisotropic thin coal beds. By analyzing seismic wave field features, it is possible for later seismic wave parameters inversion.
