摘要(Abstract)：

基于对南芬露天铁矿14种岩石的容重、抗拉强度、冲击动载强度和岩体完整性系数的测试结果,采用聚类分析方法计算了分类岩体的可爆性指数,形成了该矿山岩体可爆性的分级方法。通过在爆破生产中试验应用,确定了不同级别岩体的爆破技术参数。生产实践表明,此种方法能较为准确地反映岩体爆破的难易程度,进而确定基本合理的爆破技术参数,使爆破效果得到了一定程度的改善,对提高采矿效率和降低生产成本均具有积极意义。
Based upon the physical and mechanical parameters of rock,such as gravity,tensile strength,(dynamic) strength under impact,and integrity index,blastability indexes of the rock of 14 types of Nan-fen open pit together with the classification of rock-mass blastability were obtained through a clustering analysis method.Moreover,the blasting parameters for different levels of rock-mass were determined by making a series of field application experiments.The result of field application in the open pit demonstrated that this(classification) method could accurately reflect the actual degree of the resistance of rock to blasting,and the (resulting) blasting parameters were reasonable in general.The employment of this method resulted in an(improvement) of blasting(effect) and was favorable to raise mining(efficiency) and reduce production cost.
