To determine the structural parameters of stope using upward horizontal slicing filling mining method in Alhada lead-zinc mine,related research is carried out.A total of 2 kinds of numerical models including reserving top pillar without sill pillar and reserving sill pillar without top pillar were built by Flac3D numerical simulation software,the step-by-step simulation was used to calculate the stress and displacement distribution laws of each scheme in the recovery process,and the advantages and disadvantages of the schemes were analyzed and compared from the tensile stress,the upward swelling degree of floor and downward settling degree of roof,respectively.The results showed that tensile stress concentration occurred in the roof and floor of the goafs for both schemes after the first slicing excavation and the stress concentration occurred in wall rocks on both sides of the goaf; in the scheme of reserving sill pillar without top pillar,the tensile stress obviously declines to only around 2.30 MPa.So the scheme of reserving sill pillar without top pillar was selected as the stope structure layout form of upward horizontal slicing filling mining method in Alhada lead-zinc mine.
