Abstract: In view of the mining conditions of the soft and broken lump ore，scattered distribution of ore in northern area of Xiaoguanzhuang Iron Ore，the upward drift mining with cementing filling is selected.Through the simulation analysis，the structural parameters of the upward drift are optimized: the drift height at 3.5 m，the drift width at 3.5 m，and the path length of 60 m.In the industrial trials，the filling mining technique is improved，and some measures for improving the roof-contact filling are proposed.And the quantity of mining preparation is reduced so as to realize the safe and efficient production of the testing lump ores.

Key words: Iron mine, Upward drift mining, Cemented filling, Development engineering, Roof-contact filling
