摘　　要：采用工程中较易获得的爆破影响因素岩石容重、抗拉强度、抗压强度和岩体完整性系数作为矿岩体可爆性分级的指标,并利用AHP层次分析法确定了分级指标的重要程度,同时应用模糊变换原理和最大隶属度原则运用模糊综合评判的方法将新桥硫铁矿-270 m中段矿岩体进行可爆性分级。分级结果显示矿体可爆性为较易,上下盘围岩可爆性为中等-较难,与矿山实际情况较为符合。Using the density,tensile strength,compressive strength and rock mass integrity as the grading index coefficient,the Analytic Hierarchy Process was chosed to determine the importance of the classification for every indicators.Then the blastability classification of rock and mine in Xinqiao Pyrite-270m level was made through the application of fuzzy theory and the principle of maximum membership degree.The results show that mine could be explosived as easily,the upper and lower side of rock could be explosived as middle-difficult.This accords with the actual situation.
