In the formation of the blasting seismic wave transmission is a complex mechanical process. Blasting seismic wave in different geological structure formation of the interface, diffraction, reflection, projection as the incident Angle is different, all kinds of waveform transformation, formation of different types, different amplitude, frequency and phase of various wave superimposition of random composite wave. Blasting seismic wave propagation distance (horizontal distance and height difference), and the performance of the explosive, explosive charge, charge structure, priming method, congestion state what international airport, the plane and direction, topography and geological conditions will affect the blasting vibration effect. In engineering by empirical formula to estimate main parameters of blasting seismic wave and the structure of the empirical formula is the result of the use of theoretical analysis, by blasting of similar rate to determine the parameters in the formula is made up of many engineering measured data from statistical analysis, or directly by the measured parameters of the blasting seismic wave is given. In this paper, through various points were set in the prison line large speed is the most value, using the mathematical statistics regression analysis method, attenuation coefficient is obtained, and then back to the formula of single ring allows maximum dose safety distance calculated.
