Abstract:Selection of specific rock property parameters is the basis for quantitatively determining blastability of rock mass. Based upon comprehensive analyses of the parameters that may affect blastability,linear correlation analyses are made based on the data obtained from tests of static and dynamic properties,specific gravity,and integrity coefficients of 14 types of rock,and the results are discussed. It is found that static tensile strength and specific gravity of rock,together with the integrity coefficient of rock mass,are lightly,or not,correlated. It is proposed that these three parameters can be used to serve as the basic indexes for quantitative description of blastability of rock mass.
