- Abstract
In order to research the Influence of the strength of the filling body on the surface subsidence and deformation, with the 10203 working face of Xinyang Mine as the background, based on the numerical simulation software of FLAC3D, when the filling rate was 90%, the Influence of the strength of the filling body on the surface subsidence and deformation was researched under conditions of different strength of filling body(the strength of the filling body was 0.05, 0.1, 0.15, 0.2, 0.3, 0.4 times of the coal body). Research has shown that with the increase of the strength of the filling body, the vertical stress of the roadway roof increased; the maximum vertical displacement and horizontal displacement decreased. When the strength of the filling body was more than0.2 times of the coal body, the Influence of the strength of the filling body on the surface subsidence and deformation was stabilizing. At this time, the vertical stress of the roadway roof was 0.3615MPa; the maximum vertical displacement was 68mm, the maximum horizontal displacement was 8.5mm; which meet the requirement of the national protection of first class.
