摘要
一定种类和数量的岩体特性参数指标是对岩体的可爆性进行定量描述的依据。在对岩体可爆性影响因素进行综合归纳分析的基础上,对14种岩石的静载和动载特性参数、岩石容重以及岩体完整性系数的测试与计算的结果进行线性相关性统计分析,发现岩石静载抗拉强度、容重和岩体完整性系数3个指标线性相关性较低或完全不相关,并得出可同时采用且仅采用这3个指标对岩体的可爆性进行可靠描述的基本结论。
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.
