Zhengbeigou District of Erdaogou Gold Mine manually withdraws ores with flat bottom structures in the process of short-hole shrinkage and suffers intense labor and low ore withdrawing efficiency.What’s more,ores remain between the veins during the final withdrawal and are permanently lost.By shortening of ore drawing distance,the ore is emptied as much as possible,and the possibility of blocking between veins is reduced.The ores 2 m high at the bottom along the vein are replaced by layered waste rock backfills,reducing mining loss rate.Through setting up waste rock shafts,the stope safety is ensured,the mining loss rate and ore dilution rate are reduced,the secondary dilution caused by the upper and lower wall falling is effectively controlled,and good economic benefits are obtained.
