| 摘 要： | 基于铜山铜矿地质、地形条件,建立了矿区三维有限元计算模型,借助FLAC3D软件和地应力实测资料,基于应力边界法对铜山铜矿三维初始地应力场进行了拟合,得到的地应力场模拟值与实测值相近,实测点处最大主应力、最小主应力、中间主应力与实测值分别相差0.90,.3,0.2 MPa。分析得知,铜山铜矿原岩应力属构造应力场型。

| Abstract: | Based on geological and topographical conditions of Tongshan mine,3D finite element model is built.By using FLAC3D and measured data of ground stress,the 3D initial ground stress field of Tongshan mine is fitted with stress boundary method to get the simulation values,compared with measured datas,the difference values of maximum principal stress,minimum principal stress and the intermediate principal stress are 0.9 MPa,0.3 MPa and 0.2 MPa.The results show that initial ground stress of Tongshan mine is the section of structure stress field. |
