%X Transmitting from one material to another, wave will reflect and refract in the interface due to different wave impedance matching. Wave energy will reflect and refract, too. The energy along with reflected wave into the primary material is called reflected energy, and the energy along with refracted wave into another material is called refracted energy. Based on the theory of the transmission of reflected wave and retracted wave at interface, the transmission (including reflection and refraction) of explosion energy is analyzed and the calculating method on the rate of reflection and refraction of explosion energy and the relationship of the best impedance matching between rock and explosive are established. In addition, the influence of different kinds of charging structure(coupling charge, decoupling charge with air and decoupling charge with water) on explosion energy transmission is discussed, so that different kinds of charging structure can be applied for different engineering blasting.
