Abstract

Abstract: The global stability of Lingbao iron mine stope was analysis by RMR method and Q-system rock mass classification methods, and the results of numerical analysis on the details of stope stability and stabilty of this stope are evaluated comprehensively using ANSYS software. Stope stability of this mine is good on the current conditions, and it provides theoretical foundation for the safe stoping of ore remained in mining area.

Key words: RMR, Q system, 3D FEM, Numerical simulation, Stability
