云南某铜矿地下回采引起地面陷落的数值模拟

Numerical simulation for the surface subsidence of one copper mine in Yunnan caused by underground mining

根据云南某铜矿地下回采的具体情况,利用ANSYS有限元分析软件模拟了该铜矿地下回采过程及其对地表的影响。根据模拟结果,分析了矿房的受力情况,预测了回采过程中所引起的地表下沉位移量。

In this paper , according to the specific conditions of the underground mining of one copper mine in Yunnan ,ANSYS is used to simulate the impact of the underground mining on surface .According to the results of sim-ulation ,the paper analyzed the stress conditions of the stope and predicted the magnitude of surface subsidence caused by mining .
