| 摘 要： | 煤层开采过程中，在煤层顶、底板岩层一定的条件下，煤层的倾角和埋深对地表变形有很大的影响。通过三维有限元数值模拟，研究平缓或缓倾斜煤层、倾斜煤层、急倾斜煤层开采对上覆构筑物基础变形的影响，依据特定构筑物对倾斜变形、水平变形和基础沉降最大值的容许要求，提出安全煤柱（移动角γ、β）的保护范围，为构筑物安全运行和煤矿合理开采提供依据。

| Abstract: | During the process of mining, the surface deformation was mostly influenced by coal seam dip angle and depth when the coal seam roof and floor strata were under certain conditions. Through three - dimensional finite element numerical simulation, this paper studied the influence of the mining of the flat or gently inclined seam, inclined coal seam and steeply inclined coal seam on the founda- tion deformation of the overlying structures. The scope of protection of the safe coal pillar （ mobile an- gle T,fl） was put forward according to the maximum allowable requirements of the inclination deform- ation, horizontal deformation and settlement of foundation that the special structure requires, and it provide reference for the safe operation of construction and reasonable mining of coal mine. |
