通过对新集矿区石盒子组主采煤层顶、底板上千个试件进行室内试验测试,获取了该矿区典型岩性的密度、弹性模量、泊松比及抗压、抗拉强度等物理力学参数。并利用数理统计方法对测试参数进行回归拟合,得到了各主要参数的分布概型及最优估计参数。
Through the laboratory test of thousands of specimens on the roof and floor of the main coal seam of Shihezi Formation in Xinji Mine, the density, elastic modulus, Poisson’s ratio, compressive strength and tensile strength of the typical lithology in this mining area are obtained Physical and mechanical parameters. And using mathematical statistics method to test the parameters of regression fitting, obtained the distribution of the main parameters of the model and the optimal estimation parameters.
