摘要
针对遂昌金矿采空区稳定性数值模拟的岩体力学参数选取问题,应用RMR值计算岩体弹性模量,并对岩体内聚力和内摩擦角的选取给出了相应的计算方法,避免上述参数用传统的经验折减法选取,为采空区稳定性研究中岩体力学参数的选取提供了理论依据。
Aimed at technical difficulties of selecting rock mass mechanics parameters in Suichang Gold mine, RMR value of rock is adopted to determine the elasticity model of rock. The corresponding calculation method for selecting rock cohesion and internal friction angle are provided. Results provide important basis for rock mass stability analysis.
