To study the deep-mine rock failure mechanism and the technical issue of ground pressure manifestation using the downward approach filling mining method in the deep ore bodies in the mining area of Songxian Shanjin,the research employs rapid modeling techniques using Rhino+Griddle+Flac3D to investigate the stress and displacement patterns of ore rock during 1-8 a of downward approach mining.The simulation results indicate that the minimum principal stress increases with depth,being greater near the bottom.The unmined stope acts as a temporary ore pillar,exhibiting significant stress concentration,and a stress relief zone forms in the filling body near the stope.The displacement in each level increases with mining time,with the maximum displacement at the stope roof appearing mainly in the middle of the roof.As the mine progresses deeper,the maximum displacement value shows an upward trend.
