Abstract: Study on the law of overlying strata movement and surface subsidence in fully mechanized mining in 30104 working
face of Hamagou Coal Mine was carried out. This paper made a comprehensive analysis of overlying strata movement and surface
subsidence caused by fully mechanized mining operations from aspects such as the establishment of displacement observation
stations, the analysis of the laws of surface subsidence, the dynamic analysis of surface deformation and numerical simulation, to
provide a reasonable basis for guiding the setting of reasonable security coal pillars under the ground industrial square.

Key words: strata movement; surface subsidence; numerical simulation
