| 摘 要： | 利用ANSYS有限元大型数值模拟分析软件,通过建立某铁矿追脉开采露天高边坡三维数值模型,进行数值模拟计算,分析残采边坡的稳定性,得到结论:平硐追脉开采对某铁矿露天边坡整体稳定性影响不大,残采边坡是稳定的,但应加强平硐硐口和采空区顶板的支护和管理. |
| 关 键 词： | 追脉开采 应力场 位移场 ANSYS 残采边坡 数值模拟 |

| Abstract: | The stability of residual slope is analyzed based on establishing three-dimensional numerical model of veining up mining high residual slope of some Iron Mine and numerical simulation calculation by using large-scale finite element numerical simulation analysis software ANSYS. The conclusion shows that the veining up mining has little effect on the overall slope stability of some Iron Mine, and the residual slope is steady. It should strengthen the support and management of adit mouth and goaf roof. |
| Keywords: | veining up mining stress field displacement field ANSYS residual slope numerical simulation |
