The panel type sublevel drilling stage ore extraction followed by filling mining method is suitable for mining steeply inclined and inclined ore bodies.The roof surrounding rock of the ore body is stable,while the floor surrounding rock of the ore body is unstable.The ore body is moderately stable,with developed joints and fissures,and has a distinct layered structure,resulting in significant differences in the mechanical strength of the ore body,rock inclusions,and roof and floor surrounding rock;This mining method can achieve high efficiency and low cost mining with low ore loss and dilution,achieving the goals of safe and efficient mining,protecting the overlying high confined aquifer of the ore body,and controlling surface subsidence and subsidence.
