| 英文摘要 | We introduce a TVSP (Tunnel Vertical Seismic Profiling) technique based on coal seam waves to solve the problems of unsuitable application of conventional TVSP technique in tunnel construction to coal roadway. Some concepts are derived from theoretical analysis and numerical simulations as follows. (1) When a vertical force source (z direction) is employed to excite, the z component wavefield is less affected by roadway and the main energy of z component is Rayleigh seam wave which is suitable for reconnaissance beyond coal roadway. (2) The relatively stable Airy phase time in seismograms is used to determine travel time curves of seam waves instead of the arrivals of waves in conventional TVSP, which results in good accuracy of determination of faults. (3) When the strike angle of a fault is large, the determination of fault position (cross point of the fault line with the roadway drilling direction) has a good accuracy, but it is bad in determination of angle; when the fault is very far from the heading face, the accuracy of position determination decreases, but for the angle, it is little affected. (4) The acquisition geometry of TVSP based on seam waves is simple, the processing of data is not complicated and low computational workload is required. |
