3.We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone, including relative amplitude, phase time of wave crest, similarity factor, principal frequency band energy, 3-D space time gradient and coherent coefficient et al., and puts forward the processing method of 3-D seismic characteristic parameters about denoise-smoothing, generalization, correlation analysis, characteristic transformation; and presents the method of pattern recognition of mine engineering fracture zone.
