Abstract：Considering the characteristics of explosive, explosive source and site medium, the theoretical analysis model of correlation between fractal dimension of blasting vibration and influencing factors was established. Based on BP neural network, the fractal dimension prediction model of blasting vibration signal was established, and the method of determining the influence weight of each main influencing factor on the fractal dimension of blasting vibration signal was proposed, and the quantitative description of correlation of fractal dimension of blasting vibration signal was obtained. The research results have important theoretical research significance for further broadening the application scope of fractal theory in the field of explosion and impact dynamics, and have reference value for optimizing the design of blasting technology scheme and realizing earthquake reduction and disaster reduction.
