Abstract: On the basis of the basic principle of the dynamic finite elements analysis，and taking a Yunnan surface mine as a case，a dynamic analysis model of the slope blasting vibration is established.With the use of self-programmed procedure，the real speed time-history curve of blasting vibration is transformed into the accelerated time-history curve to calculate the loading.The modal analysis and time-history analysis of blasting vibration acceleration on slope is carried out by ANSYS software.The analysis results show that the dynamic response in the slope blasting vibration by means of the time-history method can actually reflect the dynamic characteristics of slope and the disturbance action of slope during blasting vibration.

Key words: Slope, Blasting vibration, Dynamic response, Analysis of time-history
