In order to determine the proper stope structure parameters of room and pillar mining method in a phosphate rock Yunnan pravince,the limit span of stope were calculated in different depths using the mechanics analysis methods,and the stability analysis was conducted to determine the reasonable size of pillar. Research shows that,respectively,Terzaghi theory and equivalent weight of overburden rock hypothesis as the load on roof,under the mechanical theory the limit span of stope were obtained, according to the calculation results indicate:The Terzaghi theory only applicate to the shallow overburden pressure;When use the equivalent weight hypothesis as the roof load,elastic beam theory does not apply to deep ground pressure,each other in line with the actual mechanics theory,and the pillar stability analysis is used to determine the reasonable size of pillar.This study provide certain theoretical basis and reference for the theory and practical application of the optimization of stope structure parameters.
