| 摘 要： | 对山东金山矿区３煤覆岩及底板工程地质性质类型的物理力学性质指标的变异性进行了研究，用Ｋ－Ｓ法进行的概率分布类型拟合检验表明，各指标基本服从正态分布；另外，还对煤系岩石物理力学性质指标的关联性及各向异性特征进行了初步分析，为煤矿工程地质可靠度研究提供了依据。

| Abstract: | The variability of physical and mechanical properties of various engineering geological types in the overburden and floor of coal seam No.3 in Jinshan coalfield,Shangdong Province,is studied in this paper.The Kolmogorov Smirnov tests for fitting of distribution show that the indices mainly fit logarithmic normal distribution.Moreover,the relationship among indices and the anisotropy of coal measures rocks is preliminarily analyzed.The results are basis for probability research of coal mine engineering geology. |
