Abstract: Adopt level filling method could improve mining rate greatly and reduce the dilution rate; filling by tailings from concentrator has realized resources recycling and reduced tailings reservoir pressure and protected mining area environment; dangerous of surface subsidence has eliminated and occurrence of geological hazard has reduced after cemented filling adopted at goaf. The extend and use of this mining method could get good economic and social benefits for Wuzhuang iron mine and worth learning by similar mine.

Key words: Mining rate, Dilution rate, Cemented filling
