| 摘 要： | 利用ANSYS有限元数值模拟软件,通过建立某矿追脉开采露天高边坡岩体三维数值模型,并进行了数值模拟分析计算,分析了露天矿残采边坡的岩体稳定性,结果表明,平硐追脉开采对某矿露天边坡整体稳定性影响不大,残采边坡岩体是稳定的,但应加强平硐硐口和采空区顶板的支护和管理。 |
| 关 键 词： | 平硐追脉开采 应力场 ANSYS 残采边坡 数值模拟 |

| Abstract: | Three-dimensional numerical model of veining up mining of the open-air high slope of an iron ore is established,and numerical simulation on the stability of slope residual mining by ANSYS.The numerical simulation result shows that adit veining up mining has little influence to the whole stability of open-air slope,and residual mining slope is stable,but the support and management of adit tunnel and goaf roof should be strengthened. |
| Keywords: | Residual mining slope Displacement field ANSYS Numerical simulation |
