Abstract: The high sublevel open stoping subsequent by filling mining method is adopted in a iron mine in recent years.In order to guarantee the stability of roadway surrounding rock during the mining process,the mining supporting process of the mining method is simulated and analyzed by using FLAC^3Dsoftware,and the changing characteristics of stress and displacement of roadway surrounding rock before and after the mining of upper and lower layers are discussed in detail,and the rationality of the structural parameters and supporting parameters of the stope are verified.

Key words: High sublevel stoping subsequent by filling mining method, Filling mining, Roadway stability, Numerical simulation
