Abstract: Blasting is a high-risk industry, and the safety problem has aroused widespread concern.In view of the safety problem of engineering blasting, the improved AHP fuzzy comprehensive evaluation method is applied to the safety evaluation of engineering blasting.Taking the ordinary blasting of a certain earth and stone square in Guiyang as an example, the multi level evaluation index system is constructed from four aspects of blasting area environment, blasting parameters design, construction quality and safety management.Three scale method is used to construct judgement matrix, and weight vector is calculated and fuzzy comprehensive evaluation is carried out.The results show that the total score of the evaluation system is 78.85, and the safety condition of the project is good.The engineering example proves the feasibility of the improved AHP fuzzy comprehensive evaluation method, and provides some guidance for blasting operation.
