摘　　要：为了分析煤层开采对地表运移的影响,通过数值模拟分析了包括开采厚度、松散层厚度及煤层围岩弹性模量等因素对地表运移的影响,并根据模拟结果建立了相应幂函数,分析了地表垂直运移、水平运移与各因素之间的数值关系,为分析煤层开采对地表运移的影响提供了借鉴。In order to analyze the effect of coal nfining on surface movement,the influence of nfining thickness,thickness of loose layer and elastic modulus of surrounding rock on the surface movement was analyzed by numerical simulation. According to the simulation results,the corresponding power function was set up,and the numerical relationship between the vertical movenlent and the horizontal movement of the surface with the various factors was analyzed, which provides a reference for the analysis of the influenee of coal mining on the surface movement .

关 键 词：开采厚度 松散厚度 围岩弹性模量 地表运移规律
