### Abstract

Aiming at the problem of determining the location of reasonable stop-mining line in 7311 working face of Baodian Coal Mine, the numerical model of different stoping face lengths was established by using FLAC3D numerical simulation method, and the roof stress evolution of working face with different stoping face lengths was compared and analyzed, so as to determine the location of reasonable stoping line by inversion.

### Keywords
