摘要
为了对王家岭矿区地质条件有明确的认识,充分了解煤层上覆岩层的物理力学性质,为工程设计、实验研究提供必要的物理和力学参数,通过对王家岭矿某钻孔取芯,进行了岩石密度测试试验、岩石劈裂试验、岩石单轴压缩及变形试验、岩石变角模抗剪试验,分别获得了本矿区主要岩层的密度、抗拉强度、单轴抗压强度、弹性模量、泊松比、内摩擦角和粘聚力等物理力学参数,同时确定了剪切应力与正应力之间的函数关系,对揭示覆岩破坏形式,指导安全采矿具有指导意义.
In order to clearly find out the geological and mining conditions of Wangjialing Mine,and obtain the physical-mechanical properties of overburden rock,which can provide the necessary parameters for engineering design and test study （viz.similar material model test and numerical simulation）,this paper obtained the physical-mechanical parameters,which was composed of the density,tensile strength,uniaxial compressive strength,elastics modulus,Poisson＇s ratio,internal friction angle and cohesion,and others by a coring from a drill hole of Wangjialing Mine.The relationship of function between shear stress and normal stress was determined in this experiment.
