Research on Numerical Simulation of Deformation Mechanism with Gob-side Entry Driving in Narrow Coal Pillar

Taking the C13 coal seam working face of Xieyi coal mine in Huainan mining group as research example, the deformation mechanism of gob-side coal roadway is simulated by analysis method of anyway unit and nonlinear materials technology in ANSYS software. It can be obtained from the computed result that the effect of stress distribution on roadway has a great difference with different pillar width under mining activity. Thus the gob-side pillar is most reasonable to be set for 5~7 m within the mining process for soft coal seam from comprehensive analysis results.
