Based on FLAC3D software,an optimal plan for the structural parameters of a gently inclined thick large ore body stope is introduced.In the specific research,a combination of FLAC3D software and Mathew chart method was used to obtain three optimization schemes for the structural parameters of gently inclined thick and large ore bodies,and one of the optimal schemes was selected from them.Practical application was conducted in a certain coal mine to verify the feasibility of the optimal plan and optimization method for mining site structural parameters.The verification results indicate that the optimized parameters of the stope structure can meet specific production requirements.
