为了揭示煤矿开采引起的厚松散层承压含水层失水增大地表移动变形量的机理，采用专门设计的模拟实验装置，开展松散层承压水失水沉降模拟实验，结合理论分析了松散层承压水失水对地表下沉的影响机理。实验结果表明：土体在未加压与加压的情况下，都会因为失水产生固结沉降，造成含水层的固结压缩变形；在相同条件下，细粒径土质比粗粒径土质产生的变形量更大。

To reveal the mechanism of surface movement and deformation caused by water loss in thick unconsolidated confined aquifer during coal mining, based on specially designed experimental equipment, the water loss settlement experiment of unconsolidated confined aquifer was carried out, and the effect mechanism of confined water loss in unconsolidated layer to surface subsidence was analyzed. The results show that consolidation settlement of soil can be appeared due to water loss no matter with pressure or not, which is also the reason for consolidation and compression deformation of aquifer. Under the same conditions, the deformation of soil with fine particle size is larger than that of soil with coarse particle size.
