Abstract:
Studying the scheme of gob treatment and orebody coordinated mining could not only remove the safety hazard of hidden gob, but also improve the mining efficiency of underground metal mines. Took goaf group treatment of the iron mine in the Baotou city as the engineering background, a mechanical model of goaf arch caving was built, and then the feasibility of collaborative mining scheme was verified by numerical simulation. The results showed that the pillar and roof of goaf would granually occurred sporadic caving, and then the caving rock would full the goaf, realizing the goaf group management and orebody mining. This research results could provide technical reference for safe and efficient mining of orebody under the hidden goaf.
