【摘要】 采用先进的MTS实验系统和声波测试系统,对厂坝铅锌矿岩石的单轴抗压强度、抗拉强度、泊松比、弹性模量、内摩擦角、粘结力以及岩石声波速度进行了室内试验研究,得出一系列的力学参数,这些工作为厂坝铅锌矿在多空区影响下露天转地下的过渡层开采提供了基础数据,为进一步开展岩石力学研究做好了准备。更多还原

【Abstract】 By use of the advanced MTS experimental system and acoustic wave testing system, the laboratory tests were carried out on the uniaxial compressive strengths, tensile strengths, Poisson ratios, elastic modulus, internal friction angles, viscosity strengths and acoustic wave velocities of the rocks from Changba Lead-zinc Mine, and a series of mechanics parameters were gotten. These have provided the basic data for mining the transition-layer in the conversion from opencast to underground mining under the condition of a great lot mined-area in Changba Lead-zinc Mine, and made preparation for the next studies on rock mechanics.更多还原
