本文简要介绍了蒲圻电厂～咸宁500kV输电线路工程经过游家山煤矿采空区背景，并查明了采空区的地质情况，通过建立相应的地质模型，对采空区进行了稳定性分析，并对其稳定性评价结果进行了对比及总结，通过对比得出应用覆岩破坏高度及荷载影响深度综合评价法进行稳定性分析相对科学合理，该方法可在类似采空区工程中推广使用。

This paper discussed the general conditions of Youjiashan Coal Mine goaf within the footprint of a 500kV transmission line from Puqi Power Plant to Xianning. The geological conditions at coal coaf area was preliminarily investigated. Stability analysis of coal goaf area was carried out based on a geological model obtained during the site investigation. The results of stability analysis were compared with others projects and were summarised in the paper as appropriate. The conclusion was drawn that stability approach using a combination of rupture height of overburden strata and stress distribution is more reasonable. This stability analysis approach can be applied in future projects with similar goaf conditions.
