| Abstract: | The vibration of elementary units on the sliding surface of the bench are analyzed. The relationship between the slope safety coefficient and the blasting vibration influence coefficient is determined by analyzing the moving units through the limit analysis method. And further, the critical blasting vibration accelerator and the critical vibration speed are determined based on the dynamic influence of blasting on slopes. |

| Keywords: | Blasting vibration Critical vibration speed Moving unit method Dynamic influence |
