Optimization of stope structural parameters for the orebody in the north area deep in Xishan area of Sanshandao Gold Mine
Based on the mining technical conditions of the orebody in the north area deep in Xishan area of Sanshandao Gold Mine,this study aims to optimize the stope structural parameters for the upward approach cut-and-fill mining method.10 preliminary stope structural parameters were selected and analyzed using ABAQUS software for numerical simulation.These simulation results were further optimized using fuzzy mathematics.Through comprehensive comparison and analysis,Scheme 2 is recommended for the structural parameters of the stope in the SL06154 panel of the north area deep in Xishan area of Sanshandao Gold Mine.The scheme involves a first-step stope width of 8 m,a second-step stope width of 6 m,and a stope height of 4.5 m,with an alternate mining approach for the orebody in the north area deep in Xishan area of Sanshandao Gold Mine.
