某矿山岩体质量评价与岩体力学参数研究

采空区稳定性的研究工作需要岩体质量评价结果和矿岩的岩体力学参数做根本支撑。通过现场工程地质岩体结构面的调查、岩芯取样以及室内岩石力学试验等方式,使用四种不同的方法对岩体进行了质量评价,得知大理岩、片岩及矿体为中等到差岩体,并以此质量评价所得的结论作为下一步岩体力学参数研究的基础,采用霍克布朗、摩尔库伦破坏准则以及经霍克和迪德里希斯修正的参数公式再加上加拿大专业软件RocLab的换算,求出矿山三种不同矿岩体的各项力学参数值。

Study on quality evaluation and rock mechanical parameters of a mine

The study on the stability of the goaf requires the results of rock mass evaluation and the rock mass mechanical parameters of the ore rock as the fundamental support. Through the field of engineering geology of rock mass structure surface sampling survey, core and indoor rock mechanics test, using four different methods for rock mass quality evaluation, learned that the marble, schist and ore body is moderate to poor rock mass, and the quality evaluation of conclusion as the next step the basis of studying the mechanical parameters of rock mass, with the hawk brown, the Moore cullen and the parameters and the parameters of the hawkes and didrich, and the conversion of the Canadian pro software RocLab, the mechanical parameters of the three different mines of the mine are calculated.
