摘　　要：输电线路因采矿发生杆塔倾斜、位移和倒塌现象屡有发生,采矿引起的地表沉陷与岩体变形不仅是采矿沉陷理论的核心部分,也是采矿区输电线路设计和技术改造的基础。应用数值分析中的有限元方法,建立了计算机仿真分析模型,并提出了一种新的采矿沉陷的预测方法。通过与实测资料的对比,证实了该方法的可行性,并成功应用于内蒙古乌海地区220kV伊临线路的改造工程。The phenomenon of slant, displacement and collapse of poles of transmission lines caused by mining happens frequently, ground subsidence and rock deformation caused by mining are not only the core of the mining subsidence theory, but also the basis of the design and the technological reforming of transmission lines on mining areas. A computer simulation analysis model is built up in this paper applying finite element method on numerical analysis field, and a new mining subsidence prediction method is being proposed. By comparing with the data of the factual measure, it is proved that this method is feasible, and has been successfully used on reforming project of 220 kV Yilin transmission lines at Wuhai Area in Inner Mongolia.
