摘要: 采空区塌陷严重影响输电线路的安全运行,开展煤矿采动区输电线路的安全性评估具有重要意义。以某矿某采区为例,依据开采沉陷学理论进行了输电线路下采动地表变形的预计;考虑不同的变形工况和荷载组合,采用有限元方法,得到了典型输电铁塔的抗变形性能;在此基础上,进行了输电线路的安全性评价,提出了该煤矿采动区高压输电线路的处理方案,可为今后类似工程提供参考。

Abstract: Coal mining subsidence seriously affects the safe operation of the power transmission lines. It is greatly significant to carry out the research on the safety evaluation of high voltage transmission lines in coal mining areas. Taking a mining area as a case, this paper estimates the ground deformation of transmission lines in a mining area based on the theory of mining subsidence. With consideration of different working conditions and load combinations, the anti-deformation capacity of the typical transmission towers is obtained by using the finite element method. On this basis, the safety evaluation of the transmission lines in coal mining areas is conducted and the related treatment schemes are proposed. The research results can provide a reference for the similar projects.

Key words: mining subsidence area, transmission line, safety, evaluation
