摘要
结合室内模拟钻进试验,运用多元统计中的主因子分析方法,研究了32种岩石的10种岩石物理机械性质,认为岩石的物理机械性质是以综合方式对碎岩效果产生影响,岩石的研磨性、塑性系数和压入硬度是主要因素,其次是弹性模量.
Ten kinds of physical-mechanical properties of 32 rock types were studied by using the principalfactor method of multivariate statistical analysis in combination with model drilling test in laboratory. It is believed that the physical mechanical properties exert an influence on the fragmentationof rocks in a comprehensive way. The wearlessness, plasticty index and press-in hardness of rocksare the principal factors, theeir elastic modulus being subordinate.
