For the complexity of safety system of blasting engineering,and the advantage of Artificial Neural Network (ANN) in solving such uncertain problem,ANN is introduced in this paper.Assessment model based on BP Neural Network is established,which can achieve variable weights and dynamic assessment which cannot be achieved by traditional methods.The model achieves perfect combine of knowledge and experience,reconstructed the experts knowledge and experience.The research on safety assessment model of blasting engineering in this paper is not only significant to actual using but also to the establishment of expert system of safety assessment of blasting.
