条采区巷道煤柱回收对地表建筑物采动影响研究

Study on Mining Influence to Surface Buildings Caused by Roadway Coal Pillar Recovery in Strip Mining Area

通过对高庄矿地质资料的分析,结合上覆岩层相关参数的计算及地表建筑物的现场观测,对条带开采区内集中运输巷与回风巷之间的煤柱开采后造成的地表移动变形以及对地表建筑物的影响程度进行了计算、分析和研究,并将预计结果利用MATLAB进行可视化,得到地表下沉等值线图、倾斜等值线图、水平移动等值线图、水平变形等值线图,合理解决了建筑物下压煤开采问题,为煤矿生产决策提供了理论依据。

In this article,based on analysis of Gaozhuang Coal Mine′s geological data,and combined with calculation of the overburden rocks and field observation of the surface buildings,the ground deformation and the influence of surface buildings has been calculated,analyzed and studied after drawing the pillar between centralized machine roadway and return airway in strip mining area,and the result is expected to visualize by using MATLAB,surface subsidence isogram map,inclination isogram map,horizontal movement isogram map and horizontal deformation isogram map have been got.The problem of coal mining under buildings has been solved reasonably,theoretical basis has been provided for coal mine production decision.
