Linear and nonlinear models are available to simulate the effect of mine blasting and the results change by each model. Linear model can properly simulate loss of impact wave in plastic failure region based on comparison of site vibration measurement and numerical analysis iteratively. But, loss of impact wave in plastic failure region should be calibrated into input parameter of blasting pressure. A method to convert loss of impact wave into design parameter is suggested in this study.
