地表沉陷由地下采空区顶板的冒落所造成的地面变形。在长期承载过程中，采空区矿柱系统中一些最薄弱部位往往会因风化、地震等作用而首先破坏。局部破坏的累积，最终波及整个系统。一般当矿柱的破坏率超过60％时，采空区顶板就要发生冒落，并或多或少地波及到地表。大范围的采空区顶板冒落通常是突发性的，往往伴随有强烈的气浪冲击，且多引起地表沉陷和张裂，造成地上或井下建筑物的破坏。有时，沉陷中形成的裂缝还可使地表水或地下水大量流入井下，直接威胁采矿工作的安全。如湖南锡矿山南矿就曾多次发生大规模的采空区冒落。最大一次冒落面积达34000平方米,使地表产生急剧的下沉和张裂,最大下沉量达1.075米,下沉范围近96000平方米，致使地表的一些井架和烟囱偏斜和弯曲。通常，地表沉陷的范围大于采空区。沉陷洼地的边界与采空区边界连线的倾角称移动角，是预测沉陷范围的重要数据。除此之外，最大沉陷量和下沉速度也是评价开采沉陷的重要指标，可根据经验公式进行预测。为防止这类沉陷的发生，应在采掘中合理地设计矿柱系统及开采空间的大小，以保证采空区顶板的长期稳定。在可能发生地表沉陷的地区进行建设，应采取结构措施保证建筑物不被破坏。
