To obtain satisfactory mechanical parameters of rock mass, the commonly used methods of rock mechanics parameters were compared. The study results show that differences between the different treatment methods results obtained are also larger. With the actual situation, mechanical parameters of Longqiao iron mine were selected combined by E. Hoek, elastic wave method, experience, and coefficient reduction method. The parameters of the reduction methods take the average of the results. The average modulus of elasticity of rocks were by 1/3 values of mechanical parameters. The reasonable recommended values of Longqiao iron mine were proposed.%为获取满意的岩体力学参数,对常用岩体力学参数取值方法进行了比较分析,研究发现,由于处理方法的不同,得到的结果差别也较大.结合龙桥铁矿实际情况,采用E.Hoek法、弹性波法、经验折减法及系数换算法4种方法综合考虑各种折减方法所得结果,各参数一般情况下取各折减方法所得结果的平均值,弹性模量按岩石的1/3取值,提出龙桥铁矿岩体力学参数的合理推荐值.
