Synergistic bearing and instability evolution mechanisms of roof-pillar systems in multi-level goaf groups

The synergistic bearing effect and stability of roof-pillar systems in goaf directly influence the sustainability of multi-level mining. For a multi-level goaf system, a synergistic bearing mechanical model of the roof-pillar was established. The mechanism of the roof-pillar synergistic bearing was...
