In this paper the kinematic properties of some seismic phases in DSS are presented,the mutual relations and positions 'between travel time curves of diving,reflected and head waves under conditions of the different parameters in horizontal velocity models are described. The situation about dip interfaces is also discussed. The possibility and basis for the identification of such phases are shown. Examples of application for the Suixian and Yongping explosions are given.
