(2007) analyzed the response characteristics of Rayleigh channel wave of split coal through numerical simulation; Yang et al. (2012) carried out numerical simulation research with seismic wave field of small structure, and then pointed out that the Rayleigh surface wave generated from the reflection of Rayleigh channel wave can be used as the characteristic wave of the advanced detection of small structure. According to the seismic records and the wavefield snapshots of the model, with reference to kinematics and dynamics characteristics of various types of seismic wave, all kinds of waves can be recognized from the complex seismic wavefield, and they are as follows: A direct P-wave, this direct P-wave is with circular propagation from the source to the surrounding rock.	cache/esrj-64938.pdf	txt/esrj-64938.txt
