Abstract: Due to the location and hydrogeological conditions of Sijiaying Changyu Iron Ore, no collapse is allowed at the surface.So it is planned to use the underground mining method with backfill to control the impact of rock movement on the surface The law of surface rock movement with backfilling mining method is predicted by using three-dimensional calculations through modeling and analysis Then, the surface rock movement control measures are proposed, which provides a basis for the mining, and a guidance for safety production .

Key words: Mining with backfill, Strata movement control, Mining design
