摘　　要：对于可凿性可爆性不一致的特殊矿体,不能采用目前常用的评价标准比较单一的矿岩坚固性分级方法,须对其可凿性和可爆性分别评价以确定凿岩爆破参数.其可凿性和可爆性可用其物理力学性质分别进行评价.利用线性和高次回归方法,对所测定出的特殊矿岩的物理力学性质进行相关性研究,发现矿岩的波阻抗Z、弹性模量E和抗拉强度σL最能反映矿岩可凿性可爆性,并对凿岩爆破工作提出了可行建议.图5,表2,参10.The special ore-bodies studied in this paper,which have variant drillability and blastability,cannot be classified by use of any actual classification method which has simple standard.It must be evaluated by drillability and blastability separately,which can be reflected by physico-mechnical properties.With use of linear and hypo-regression,the relativities between physico-mechnical properties and drilliability and blastability of ore-bodies were studied in this paper.The wave impedance Z,elastic module E and tensile strength σ_L can reflect the drillability and blastability effectively.The feasible reference is provided for similar blasting engineering on drilling and blasting.5figs.,2tabs.,10refs.
