To determine the reasonable stope structural parameters for the sublevel drilling stage open stope and subsequent filling mining method in Hongling Lead-Zinc Mine,numerical simulation was employed to study 16 different scenarios with roof thicknesses of 3 m,5 m,7 m,and 10 m,and stope lengths of 20 m,30 m,40 m,and 60 m,respectively.The stress,displacement,and plastic zone distribution of each scenario with a roof thickness of 3 m were compared.The results indicate that the stability of the stope in Hongling Lead-Zinc Mine is fairly good when the roof thickness is 3 m and the stope length is 35 m for the sublevel drilling stage open stope and subsequent filling mining method.
