| 英文摘要 | Whether concealed small faults in coal seams can be found out during geological exploration is a main geological factor that affects the safety production of a coal mine. Seam Channel waves in coal seams are very suitable for detecting abnormal structures in a coal field, because they are characterized by strong energy, obvious dispersion and easy to identify. In this paper, we use the spectral element method to simulate 2D Rayleigh channel wave propagation in coal seams containing small faults, and analyze the characteristics of wave fields, dispersion and spectra of direct, reflected and transmitted channel waves. Based on different fault models with small throws (vertical offsets 1/4, 1/2, 3/4, one thickness of a coal seam; dips 90 degrees, 60 degrees, and 45 degrees), we address the influential effects of small faults on these waves. By virtue of the analysis above, we obtain some new insights into Rayleigh channel wave in coal seams with small faults, and discuss the application of such waves in exploration. |
