| 摘 要： | 地表移动和变形对铁路路基、线路产生严重影响。铁路下采煤应满足一定的采深与采厚比,防止地表突然沉陷或消除和减轻地表变形的叠加影响,应合理布置工作面,留设好铁路煤柱,并采取地面维修措施。

| Abstract: | The surface movement and deformation have serious influence on the railway embankment and lines.Mining under railway should meet certain mining depth and mining thickness ratio,in order to prevent a sudden surface subsidence and reduce or eliminate the superposition of surface deformation effects,should rationally arrange faces,retain railway pillars,and take measures of ground maintenance. |

| Keywords: | mining under railway mobile surface deformation technical measure |
