Abstract: Applying numerical software FLAC5.0 to simulating different supporting projects of air-roadway at-870m in Zhuji Colliery of Huainan Mining Group,plastic area distribution,stress distribution and deformation characteristic of surrounding rock under different supporting projects was analyzed.Results showed that deep roadway with high-stress should be controlled by combined supporting.A concept of constructing closed loading structure in surrounding rock of roadway was put forward,which could provide reference for roadway stability control.
