三岔河矿区矿体岩石物理力学试验研究

Experimental study on Physical and Mechanical Properties of Rock for Sanchahe Mining Area

通过对三岔河矿区岩体进行试验研究,得出了该矿区具有代表性岩石的密度、单轴抗拉强度、单轴抗压强度、剪切强度、内摩擦角、粘聚力、弹性模量和泊松比等岩石的物理力学性质;并通过对岩石物理力学参数进行工程处理,得到了符合工程实际的岩体力学参数,为开采设计、物理模拟、数值模拟和实际生产提供了科学依据。

Some tests on the properties of rocks from Sanchahe mining area were made, and the physical and mechanical parameters of the representative rocks, such as density, tensile strength, uniaxial compressive strength, shear strength, internal friction angle, cohesive strength, modulus of elasticity and Poisson＇s ratio, were obtained. The proper engineering processing of the physical and mechanical parameters was made to make them be better in accord with the actual engineering situations. The processed parameters provide scientific basis for mining design, physical simulation and numerical simulation, as well as actual production in this mining area.
