Abstract: Taking Daliuta Mine as the engineering background, the law of surface movement and subsidence observation in Daliuta Mine was studied by using numerical simulation method and field data analysis. The numerical simulation analysis shows that the rapid advance of the working face makes the subsidence speed of each layer of the overlying strata of the coal seam faster, the relative suspension time is reduced, and the movement deformation is concentrated. The measured analysis shows that the time from the surface subsidence to the maximum subsidence of 430 mm/d is short, and the subsidence is large. The maximum subsidence at point Z10 on the observation line is 3.959 m. The subsidence at the bottom of the subsidence basin is large, and the subsidence near the boundary of the mining area decreases rapidly. The subsidence basin is extremely steep, and the convergence of the subsidence basin boundary is fast. The time from the surface movement to the maximum subsidence is less than six months, and the stability time is long. Finally, the time from the subsidence of 100 mm to 10 months achieve stability.
