| 摘 要： | 本文阐述了应用绕射波探测坑道掌子面前方小构造的技术,在速度低于上下围岩的中等速度的特定层位中,地震波将在前方的小断层或小构造处反射,以绕射波形式返回到检波器,其最远的探测距离达184m。

| Abstract: | In this paper, an application of the diffraction wave to the small structure probing is discussed. In the layer of the medial or lower velocity along the tunnel, the seismic wave reflects at the small fault surface or structure in the front of the stope face and , as a diffraction wave form, returns to the receiver. The forthest distance obtained in such probing is about 184 m. |
