鹿鸣钼矿岩体宏观力学参数确定与优化

摘要

Taking the West-I area in Luming Molybdenum Mine as the study example,the rock mass quality is evaluated and classified by using Bieniawski rock mass geomechanics classification method,the evaluation and classification of the rock mass quality of North area and West-I area of Lumining Molybdenum Mine are completed. Based on the evaluation results of rock mass quality,the rock mechanical parameters is converted in to the ones of rock mass by using the international Hoek-Brown empirical function, the mechanical parameters include bulk modulus, shear modulus, internal friction angle, cohesive strength,compressive strength and tensile strength. The above analysis results in this paper can provide the parameters condi-tions for the slope stability calculation.%以鹿鸣钼矿西-I区边坡为研究对象,采用宾尼奥夫斯基节理岩体地质力学分类法对鹿鸣钼矿岩体质量进行评价和分类,完成了鹿鸣钼矿北区和西-I区岩体质量评价与分级.根据岩体质量评价结果,通过国际通用的Hoek-Brown经验方程将岩石力学参数转变为岩体力学参数,包括岩体的体积模量、剪切模量、内摩擦角、黏聚力、抗压强度和抗拉强度等,为边坡稳定性的计算提供了参数条件.
