This research simulated the super-large-scale continuous panel multi-level mining and filling process of a super-large iron mine, and the stress perturbation law was focused on. Results show that the overlaying effect of muti-level mining has negative effects on the stability of the 26m-wide pillar apparently.There are stress-releasing area between two levels and obvious stress concentration areas below Level -580m. The result can be a good reference for continuous panel super-large-scale mining and stress-releasing mining in deep mine.
