Abstract: Hongnipo Copper Mine is characterized by large amount of resources，high grade ( up to 1.67% ) ，easy separation and stable rock. But the surface covers farmland，part of industrial facilities and villages，which is a“three mining”deposit with complex mining conditions，so aiming at the safety of surface facilities and the safety of the next orebody mining，the scheme of cemenled filling with full tailings + graded crushed gypsum body and the scheme of cemented filling with graded tailings are put forward respectively. In addition，the two filling schemes are systematically compared and analyzed from the main technical and economic indicators such as system construction cost and operation cost. The results show that the scheme of full tailings + graded crushed gypsum body gravity flow + pumping filling has the advantages of low operation cost，low total filling cost(24.78 yuan/t) and high ore recovery rate.Finally，the scheme of full tailings + graded crushed gypsum body gravity flow + pumping cemented filling is determined.
