Abstract In view of the surface deformation caused by horizontal mining in No.14 coal seam of Meiyukou Coal Mine, according to the surface subsidence caused by the difference of geological conditions of the working face, combined with the traditional dynamic measurement technology and real-time monitoring technology of rope deformation and displacement, the three-dimensional deformation and displacement of the characteristic points in the subsidence area were monitored. The data analysis showed that the surface deformation was stable at the northwest end of the working face, and the vertical and horizontal deformation of the surface was serious at the southeast end of the working face. Through dynamic observation and real-time observation, the deformation parameters of the surface could be accurately obtained, which accumulated experience for subsequent research.
