摘要(Abstract)：

矿岩可凿性和可爆性对确定凿岩爆破参数起重要作用,但测定须用专门器械,测定过程比较复杂,而且测定方法与具体的凿岩爆破工艺密切相关。然而矿岩物理力学性质的测定则比较简单。利用线性和高次回归方法,通过对这些性质内在的相关性进行研究,发现矿岩的波阻抗、弹性模量和抗拉强度最能反映矿岩的可凿性和可爆性,这对凿岩爆破机理和设计的研究是有用的。
The drillability and blastability of rock are important for choosing the parameters of drilling and blasting but mensuration of them is relatively complex with special instrument and closely relative to actual drilling-and-blasting technology.However,determination of the physico-mechanical properties of rock is relatively simple.With use of linear and higher regression,the correlation of physico-mechanical properties to drillability and blastability of rock is studied in this paper.It is found that the wave impedance Z,　elastic module E,　and tensile strength σ_L of rock can reflect its drillability and blastability effectively,which is useful to the research of mechanism and design of drilling-and-blasting.
