Abstract： With the continuous improvement of coal mining intensity, environmental problems such as surface subsidence and gangue hills have become increasingly prominent, and filling mining is an effective means to solve this problem. In this paper, taking the 15101 fully mechanized mining face in the north first panel of the first mining panel of Qiyuan Coal Mine as an example, the design of gangue filling mining is studied, the source and quantity of gangue in the mine are analyzed, and the underground gangue separation process and filling process are determined by research and calculation. The practice shows that the application effect of the designed gangue filling mining scheme is good, and all the gangue in Qiyuan Mine is backfilled into the goaf, which realizes the coordinated development of resources and environment in the mining area.
