Abstract: In order to study the influence law of blasting vibration on slope stability，and to reveal the key technical parameters of blasting，the plane sliding stability coefficient calculation formula was established with the consideration of vibration stress.Based on the numerical simulation analysis method，the stability coefficient variation law of the west slope in Buzhaoba surface mine when influenced by blasting vibration was analyzed，the results showed that the slope stability coefficient has a logarithmic growth with the distance from the explosive center increase.When the distance is longer than 300 m，the influence of blasting vibration on the west slope stability can be ignored.The synergistic effect of slope stability coefficient and vibration velocity is higher，the peak appeared at the same time and the amplitude satisfied the proportional relationship.

Key words: Blasting vibration, Surface mine, Slope, Stability
