摘要
在西南某矿山体赋存条件的基础上,建立了相应的数值模型,模拟得出地表起伏对垂直应力的集中程度的影响;分析出水平应力与其对应地表的位置有密切关系。在应力分布规律的基础上进行了支护技术研究,结果表明在250m埋深以浅,锚杆支护可有效控制巷道变形,对类似巷道支护设计有着很大的参考价值。
On the basis of occurrence condition of the mountain body in a mine in southwest Guizhou, the corresponding numerical model is established, which simulates out the impact of surface undulation on concentration of vertical stress. It is concluded that the horizontal stress is closely related to the position of the corresponding surface. On the basis of stress distribution law,support technology is studied. The results show that the bolt support can effectively control roadway deformation above 250 m depth, which has great reference value for similar roadway support design.
