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.
通過對金山金礦礦巖的抗拉彊度、抗壓彊度、抗剪彊度、泊鬆比、彈性模量、內摩抆角以及內聚力的室內試驗,分析瞭金山金礦礦巖力學特徵,提齣瞭礦體、上下盤圍巖各嚮同性特徵差,呈現齣較彊的各嚮異性特徵.在實際工程應用中,應按各嚮異性礦巖來處理.

@@@@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 .
