Abstract: It is an important part of the green mining system to use underground gangue directly for filling and replacing "threeunder"
compressed coal. This paper described the basic ideas and technological routes of the gangue filling and mining in roadways
of Licun Coal Mine, and analyzed the factors affecting the recovery rate. Using the prediction theory of surface subsidence,
and comparing with the non-filling mining under similar geological conditions, it is obtained that the mining of roadway gangue
filling method has a significant effect on the control of surface deformation.

Key words: gangue filling; deformation; surface control
