摘要
通过对金山金矿矿岩的抗拉强度、抗压强度、抗剪强度、泊松比、弹性模量、内摩擦角以及内聚力的室内试验,分析了金山金矿矿岩力学特征,提出了矿体、上下盘围岩各向同性特征差,呈现出较强的各向异性特征。在实际工程应用中,应按各向异性矿岩来处理。
After experimental research of the tensile strength,compressive strength,shear strength,Poisson’s ratio,modulus of elasticity,internal friction angle and cohesion of the ore rock from Jinshan gold mine,the paper analyzed its rock mechanics characteristics.And then the difference of isotropic characteristics of the ore body is put forward which assumes strong anisotropic characteristics.So in actual project,it is proposed that the rocks be treated as anisotropic.
