Abstract: Limited by the thickness and dip angle of the ore body,the gently inclined extremely thin ore body is difficult to mine safely and efficiently.Such is the case in Daliuhang Gold Mine which uses short-hole shrinkage mining method to extract the gently inclined-inclined extremely thin ore body but achieves poor resource recovery rate,poor mining efficiency and unsatisfactory economic and technical index.In light of that,experimental study on the fan-shaped upward resuing filling mining method is carried out as well as the industrial test in No.1153 stope in Yanshan Mining District.Engineering practice shows that the mining effect of the mining method is good,technical and economic indicators have been significantly improved,the mining loss rate decreases to 2.67 % and the ore dilution rate drops to 30 %.The study provides reference for the exploitation in similar mines.
