采动条件下矿区铁路及站场变形预计系统研究

Research on deformation prediction system of minefield railway line and railway station under mining activity conditions in underground

针对铁路下的煤层被采出后,采空区上方的岩层和地表移动导致的铁道线路及其他建筑物移位的问题,提出了厚煤层条件下放顶煤开采区的矿区铁道线路及站场道岔群的沉陷预计系统,掌握铁道移动与变形特点及动态变化规律,从而提出合理的线路维护措施尤其是铁路站场道岔群变形的治理技术,可保障铁路运输生产的正常进行及行车安全。

After the seam under the railway line mined out, the displacement of the strata and surface ground above the goaf would cause the displacement problems to the railway lines and other building structures. The paper provided the ground subsidence prediction system for the railway line and the railway switch groups in the railway station within the mining area, where a top coal caving mining in thick seam operated in the underground mine. With the subsidence prediction system, the displacement and deformation ...
