鹿鸣钼矿西-Ⅰ区边坡稳定性相似材料模拟

为了保证露天矿安全生产,需要对边坡稳定性进行分析和优化。在对鹿鸣钼矿前期的地质资料和岩石力学参数进行研究的基础上,针对矿区的弱结构面区域2-2剖面,以几何相似常数300为比例搭建实验室模型,布置位移监测点及应力监测点,模拟实际边坡开挖过程,采集相关数据分析边坡稳定性。通过模拟分析得到2-2剖面240m平台和270 m平台存在失稳的可能性。在露天边坡开挖工作中,台阶边坡容易发生变形破坏,弱结构面与断层有交叉和台阶边坡位于弱结构面区域更易发生变形破坏。研究结果为鹿鸣钼矿的安全生产提供了一定的理论依据。

Similar Materials Simulation of the Slope Stability at the 1st West Zone in Luming Molybdenum Mine

In order to ensure the safe production of the open pit mine,it is necessary to analyze and optimize the stability of the slope.Based on the study of geological data and rock mechanics parameters of the Luming Molybdenum Mine,in view of the weak structure section 2-2 of mining area,the similar material simulation test model was built by the proportion of geometric similarity constant 300 to arrange displacement monitoring points and stress monitoring points.Then the excavation process of the actual slope was simulated with this model,and the slope stability was analyzed with the related data collected.Through the simulation analysis showed that 240 m platform and 270 m platform at section 2-2 have the possibility of instability.In the excavation of open pit slope,beach slope is prone to deformation and failure,the weak or cross beach slope located at the weak structure or fault are more prone to deformation and failure.The research results provide a theoretical basis for the safe production of Luming Molybdenum Mine.
