When mining inclined ore body with sublevel caving method, it is easy to produce residual ore loss at the footwall. First of all, the influence of orebody thickness, orebody dip angle, sublevel height, drift spacing and other factors on the percentage of footwall residual ore is analyzed theoretically. The analysis results show that the footwall residual ore decreases with the increase of orebody thickness and dip angle, and increases with the increase of sublevel height and drift spacing. Then, under the condition of inclined medium-thick ore body, the proportion of residual ore in the footwall when the footwall rock cutting is retreated to different positions is analyzed. The result shows that the full recovery of the footwall ore can not be achieved by using only the medium-deep hole rock cutting mining, and the proportion of residual ore in the footwall usually reaches 10%~15% of the segmented ore, or even higher. In order to fully recover the residual ore in the footwall, the technical scheme of "footwall rock cutting withdrawal+auxiliary route recovery of residual ore in the footwall" has been put forward. The effectiveness of this scheme has been verified by physical ore drawing simulation experiment. The experimental results show that compared with the single medium deep hole footwall rock cutting withdrawal method, this scheme can increase the ore recovery rate by 6.4%, while the dilution rate only increases by 0.4%. Finally, the scheme is applied to the field production practice and has achieved good application results.
