The characteristics and calculation methods of RFPA’98 numerical simulation software are introduced. Combined with the research of deep column-free continuous mining in Xiangxi gold mine, a numerical simulation calculation model of stope is established and the stability of stope is analyzed. Through the calculation, the stress distribution in stope mining process is simulated accurately, which provides a reliable theoretical basis for optimizing stope structure parameters and guiding stope ground pressure control.
