Abstract: Reasonable stope structure parameters are an important guarantee for mine safety production. Based on the theory of game theory,an innovative combination weighting method (A&C) for optimizing the structural parameters of underground mine stopes considering both analytic hierarchy process (AHP) and CRITIC method is proposed. The structural parameters of 8 groups of stopes in a tungsten mine are simulated and calculated by FLAC 3D ,and the combined membership matrix is established. Based on the comprehensive analysis of the stress,displacement,plastic zone and recovery rate of each scheme,the optimal stope structure parameters are obtained by sorting the superiority. The research shows that this method can reasonably optimize the stope structure parameters of underground mines,which has certain guiding significance for similar mines.
