【Abstract】 In this paper, the basic theories of wavelet transform and two-dimensional fractional technology are introduced, and the application of both techniques in Xuchang Coal Mine is also described in detail. The theory and practical analysis show some conclusions. In predicting Ordovician limestone karst fractured zones, the wavelet transform can enhance signal/noise ratio (S/N) and the resolution of seismic signals; the parameter of two-dimensional fractal has its own value; and the combination of them is an effective method.更多还原
