According to the phases-subsequent filling method in large iron ore of southern district Sijiaying, the current conditions of ore body and requirement of mining are analyzed in detail. By taking into account of factors such as protection of water resources and environmental, control of rock movement, efficient and large-scale mining, deceasing of losses and dilution, the stope structure optimization is carried out. After analysis on the main factors of economy and security, the value range and constraint conditions are defined, and a series of threedimensional numerical analysis are performed. By regression analysis, the functional relationship between mining safety-rock movement parameters and the design parameters are achieved. By solving the optimization model, the optimization structural parameters of the stope are obtained.
