基于ANSYS的地下矿山凿岩硐室稳定性分析

The Stability Analysis on one Drilling chamber of a Underground Mine based on ANSYS

为了研究地下矿山凿岩硐室的稳定性问题,运用有限元软件ANSYS建立硐室的数值模型,模拟硐室开挖前后不同的受力状态,计算出对应的位移量,对比开挖前后的等效应力、等效弹性应变、等效塑性应变,得到硐室围岩的应力应变分布情况,对于高地应力环境凿岩硐室围岩加固和支护具有指导意义,对于确保矿山凿岩硐室内人员和设备的安全具有重要意义。

The finite element software ANSYS is applied to establish the numerical model of chamber in order to study the stabil- ity problem of one drilling chamber of a mine, the software can simulate the different stress state before and after excavation, the correspond- ing displacement can be calculated, compare to the equivalent stress, equivalent elastic strain, equivalent plastic strain before and after ex- cavation, the stress strain distribution of the surrounding rock of the chamber can be got, which has the guiding significance to the reinforce- ment and support of the surrounding rock of chamber, which has the important meaning to ensure the safety of indoor people and equipment inside the mine chamber.
