Abstract: Chambishi Copper Mine, which belongs to Africa Mining PLC of China Nonferrous Metals Co., Ltd., is a high grade deposit and broken roof.It is the typical gently inclined medium-thick bodies.The cut-and-fill stoping mining method was adopted.In order to get the reasonable structure parameters, the stress and deformation condition in surrounding rock was analyzed in different stopes arrangement method by ANSYS.The optimal stoping scheme that stopes layout perpendicular to the ore body was determined.Compared with the simulated results of nine kinds of typical stope structure mode, the optimal structure parameters of stope as 4.3 m room and 4.0 m pillar is determined finally.

Key words: Numerical simulation, Gentle inclination medium-thick orebody, Stopes arrangement method, Structure parameters of stope
