| Abstract: | A numerical calculation model was established for stoping based on the mining method. Simulation calculations were conducted using finite element analysis software for the stress of stope's roof and floor, as well as the displacement situation based on different mining sequences. Meanwhile, surface displacement caused by different mining methods was analyzed. An optimal stoping sequence and a mining program were finalized. It can provide some technical guidance for the safety and efficient production on mine. |
