To explore the movement patterns of overburden in strip filling mining, this study takes a mine in Tuokexun as the research object and employs theoretical analysis, numerical simulation, and similar experiments to investigate the stability of the composite structure in upward mining faces and the stress distribution and fracture characteristics of the overburden at different stages of strip filling mining. The results indicate that when the width of the isolation coal pillar is set at 15 m and the filling body width is 150 m, a stable supporting structure can be formed. During the filling mining stage, the range of overburden damage presents an upward-tilting trapezoidal distribution, yet remains overall intact, significantly reducing the probability of impact hazards. In the collapsed mining stage, the initial fracture step distances of the immediate roof and basic roof are 40 m and 80 m, respectively, with a periodic fracture step distance of 20 m. The overburden displacement is relatively gentle, and the degree of stress concentration is low, which is beneficial for the stability and safety of underground mining.
