Taking economy,quality and safety as the first grade index,and 13 factors such as the cost of explosive,the percent of block with qualified size,the safety distance of blast vibration,etc.,as the second grade index,a evaluation model of effect of deep-hole blasting in open-pit mine are established.The weights of each grade index were calculated by use of analytic hierarchy process(AHP).After quantizing the qualitative indexes and taking quantitative indexes into non-dimensional,the estimated results were evaluated with fuzzy comprehensive judgment and blasting scheme was chose.The application showed that the blasting scheme chose by the evaluation model can meet the requests of blasting,the evaluation model is of certain guiding significance for the optimal selection of field scheme of deep-hole blasting in open-pit mine.
