Abstract: The joints and fractures of the broken stope in the southeast area of Meishan Iron Mine are developed,the stability of the rock is poor,the ore recovery rate is low,and there are a lot of residual ores.In order to fully recover the residual ore in the upper levels,an experimental study on induced caving mining method was carried out.According to the structural plane survey and stability classification in this area,the stability classification of -303 m and -318 m level of ore bodies is in the unstable to extremely unstable range,and it is easy to fall.Based on the principle of arched fall,the stress state of the surrounding rock of the roof was analyzed,and the continuous fall span of the roof rock mass which caused the mining space was calculated to be 34.2 m.Therefore,a twostep mining method of induced caving method was designed.Induced caving was adopted in -303 m level rock mass,and then the -318 m level ore was recovered.In order to reduce the damage of the blast hole,the length of the blast hole in -318 m level was shortened.According to the design,the middle of -303 m segment S5~S8 normal mining approach is reinforced to encrypted approach.According to the ore flow rule and spatial location of the residual ores,the -318 m level S7 and S8 approaches are designed as the main trench recovery lanes,S6 and S9 are used as auxiliary recovery lanes.According to the field mining test results,the apparent recovery rates of the S5 and S6 approaches in the -303 m level reached 151.18% and 193.97% respectively;the apparent recovery rates of the S7 and S8 approaches in the -318 m level reached 129.15% and 134.05% respectively,which further show that the application results are significant.
