彬长矿区为黄土残塬沟壑地貌，煤层开采厚度大，覆岩中洛河组、宜君组砂岩厚而坚硬，地表黄土覆盖层厚，地表纵横切割，开采地表移动变形具有一定的特殊性和复杂性。为掌握厚湿陷性黄土层非充分采动地表移动规律，确定开采对地表建筑物的影响程度，在地表及建筑物观（监）测的基础上，结合建筑物下采空区及其覆岩结构稳定性计算分析、数值模拟和地表剩余移动变形预计等方法，对采空区影响彬长生产服务中心地表建筑物及其危险性进行了深入分析。 地表与建筑物移动观（监）测结果表明，彬长生产服务中心厂区地表移动变形活跃期和衰减期相对较短，工作面开采结束14个月后地表沉陷盆地进入稳态状态。应用覆岩变形理论和数值模拟分析得出，107工作覆岩中存在控制采动岩层变形破坏的关键层，关键层能够有效地控制岩层移动继续向上发展，并在关键层下位形成了较大的离层空间，关键层的变形仅为在土层重力和自重的作用下产生的挠曲变形，地表下沉盆地非常平缓，在单一工作面开采条件下，其成为控制地表沉陷的关键因素。应用概率积分预计法对地表剩余移动变形进行计算分析，结果表明地表水平变形对综合服务楼、探亲楼、职工宿舍楼有不同程度的影响，这与实际地表移动变形对建筑物的影响基本一致；并预计了南北区地表剩余移动变形，得出107工作面开采地表沉陷盆地已经处于稳态状态，对厂区建筑物影响已经很小，同时对出现裂缝破坏的建筑物经加固维修后，至今未出现再次破坏。

As the thick coal seam mining and thick and hard sandstone in Luohe and Yijun formation, the mining surface movement deformation has a certain particularity and complexity in Binchang mining area, where is covered by thick loess and the gully-cutted surface. In order to grasp the law of the subcritical mining surface movement under thick and wet sinking loess layer, determining the impact of mining on surface buildings, based on surface and buildings observation, by calculation and numerical simulation of gob under buildings and its structural stability as well as predicting surface residual deformation, a deep analysis is conducted to the influence of gob on the surface building of Binchang production service center and its risk. The surface and building monitoring test results show that,he active phase and decay phase of surface movement deformation in Binchang production service center are relatively short, the surface subsidence basin enters the steady state 14 months after mining. According to the overlying strata deformation theory, there is key stratum that control mining strata deformation and failure in the overlying strata above face 107. The key stratum is able to effectively control the upward development of strata deformation, and form a large separation space under the key stratum. The key stratum deformation is only the deflection caused by soil gravity and self gravity, thus the surface subsidence basin is very flat, which become the critical control factors of surface subsidence under the condition of single working face mining. According to probability integral method, the surface residual deformation is analyzed. The result shows that, the surface horizontal deformation have different impact on comprehensive service building, visit building and employee dormitory, which is in accordance with the actual. The surface residual deformation of North and South areas is also predicted, and finds that the surface subsidence basin of face 107 is in steady state. The building in this area is under little influence. Meanwhile, so far there has not been any damage on buildings that appear cracks after reinforcement.
