摘要
针对矿井开发日益向地壳深处发展的现状,根据岩石力学和流变力学原理,分析了矿井在深部开采条件下开采深度和温度对围岩应力和变形的影响。采用大型通用有限元分析软件ANSYS,建立二维模型并对某矿井进行了数值模拟,184号节点在1500和2000m深度下,矿井岩石的应力分别为42和56MPa,位移分别为1.18和1.57m。结果表明:围岩的变形随时间的增加而增加,并且围岩的应力与变形随开采深度(温度)的增加而增加。
Directed at the mine＇ s tending to go increasingly deeper, the paper features the analysis of the impact of the operation depth and temperature of the deeper mines on stress and deformation of surrounding rocks, based on the principle of rock mechanics and fluid mechanics. The two-dimensional model is built and the numeric simulation of stress and deformation of deep tunnel adjacent rock is performed by means of the powerful finite element analysis software ANSYS. Stress of 184 node is 42 and 56 MPa while deformation is 1.18 and 1.57 meter at the depth of 1 500 and 2 000 meters. The result shows that the stress and deformation of rock vary with the operation depth and temperature.
