摘    要:煤矿开采向深部转移时,应该存在一个安全开采深度,在该深度以下开采时,地面建筑物不会发生破坏性变形。依据地下开采时地表任意一点地表下沉计算为基础,结合地表倾斜、曲率、水平移动变形,按照砖混结构建筑物的临界变形值,得出了煤矿安全开采深度的判定方法与计算公式,并探讨和分析了安全开采深度的影响因素。

关 键 词:安全开采深度  临界变形  倾斜变形  曲率变形  水平移动变形

Abstract:While cola mining transfers to deep place, there should be a safety mining depth, under the which the destructive deformation of the surface structures can not occur. Based on the subsidence calculation of a willful point on the surface, combining the surface sloping, curvature and level displacement deformation, and according to the critical deformation value of the concrete and brick structures, a judgment method and calculation formula of safely mining depth of a coal mine are obtained. In addition, the factors influencing safely mining depth are studied and analyzed.
