Abstract: A large number of residual ores in the intermediate pillars,crown,and sill pillars left by the shrinkage mining process adopted in the upper deposit of Chaihulanzi Gold Mine are highly economically valuable.To further improve the utilization rate of residual ore resources,this paper based on the existing scheme of the mine proposes 4 overall mining technology schemes for residual ore resources.Based on ABAQUS numerical simulation software,the corresponding numerical simulation model is established.The size striking direction extends 420 m,the vertical direction 616 m,and the height 160 m;the width of the surrounding rock is 50 m.The recovery rate,displacement field,and surface subsidence of different schemes were obtained,and the optimal technical extraction scheme was finally determined to be the horizontal and vertical striped evenly supported ore pillar extraction scheme through comparative analysis.The results show that in actual production,the scheme can maximize the economic benefits under the condition of safe mining while recovering the residual mineral resources under the non-cemented waste rock filling body.
