Overall subsidence of approximately 48.7 mm was observed due to cumulative mining activities, confirming surface stability.
The geomechanical model built using FLAC3D assessed the stability of overlying strata under mining influences.
Stress concentration reached 83.34 MPa during deep ore extraction, mostly affecting excavation areas.
Integrated theoretical and numerical approaches provide tools for evaluating mining-induced surface risks.
