摘　　要：基于工作面的工程地质、岩土体的物理力学指标和短壁开采的特点,在工作面回采过程中对地表进行下沉监测,并利用FLAC3D软件进行相应的数值模拟,将工程实测和数值模拟的结果进行验证分析,得出连续采煤机短壁机械化开采条件下地表沉陷规律。According to engineering geology of working face, physical mechanic index of rock-soil mass, and features of short-wall mechanized mining, surface subsidence was monitored in the mining process. The results, from engineering detection and numerical simulation with FLAC3D software, were tested and analyzed to determine the surface subsidence law caused by the short-wall mechanized mining with continuous miners.
