Abstract: Stress-relieve sublevel caving is an effective method developed recent years to solve the problems caused by mining unstable and inclined medium-thick orebody, but it has disadvantages of high ore loss and dilution. To solve the problem, the reason for the high loss and dilution is analyzed in the light of the flowing characteristics of ore-rock granular in inclined medium-thick orebody. The diversion drawing technique is then proposed. The influence of the position of a draft on the loss and dilution was investigated comprehensively through physical simulation experiments. The effects of diversion drawing was compared with the results of non-diversion drawing experiments. It is found that the diversion drawing technique can significantly improve the ore loss ratio and dilution ratio, especially for the efficient recovery of the footwall ore residue. The parameters' range of stress-relieve and diversion were obtained through experiments.
