Abstract: Surface subsidence caused by coal underground mining leads to different degrees of damage to surface buildings, and depicting the characteristics of surface movement and deformation accurately is an important basis for underground protection of coal column retention and mining damage evaluation. Based on the field measurement data and theoretical analysis of mining surface subsidence, analyzes the migration law of bidirectional main section of the mining surface under the condition of large-scale mining height in Daliuta Mine, and inverts the feature boundary of the surface subsidence characteristics. The results show that the maximum sink value in the direction of the inclination main section is −3 589 mm, the maximum value of the positive inclination value is 50.4 mm/m, the maximum value of the positive curvature value is 1.18 m⁻¹, located at the position of 574.976 m, and the minimum value of the negative curvature value is −1.4⁻¹ m, located at the position of 524.936 m. With the gradual advancement of the working face, the surface subsidence curve of the strike main section shows typical dynamic evolution characteristics, from the surface sinking curve from V shape to U shape, the maximum sinking value is −3 959 mm, the maximum value of positive inclination value is 55.7 mm/m, located at the position of 700.013 m, and the maximum value of the positive curvature value is 1.59 m⁻¹, located at the position of 700.013 m. The surface subsidence coefficient is 0.61, the horizontal movement coefficient is 0.32, the main impact radius is 71.1 m, the main impact angle tangent is 2.88, the leading impact angle is 53°, and the maximum sinking velocity hysteresis angle is 70°. The measurement and inversion reflect the real situation of surface movement and deformation, which lays a good foundation for the study of surface subsidence rule and the calculation of rock movement parameters in Daliuta Mine, and also provides important basic data for mining surface monitoring and characteristics boundary inversion under similar geological conditions.
