Abstract: In order to solve the problem of rock burst and roadway large deformation controlling in thick coal seam with bump proneness of deep shaft， apply the control principle theory of gob-side entry driving in narrow coal pillar and stagger position roadway layout， Huafeng Coal Mine took the experimental study in 1411 air return roadway. By the deformation of roadway and microseismmic monitoring data， following result was obtained： stagger position roadway layout can solve the problem of the strong and frequent rock burst and roadway large deformation of 1411 air return roadway. It realized that the mine earthquake over 0.8 were reduced by 87%， the convergence between roof and floor was reduced 132.5mm and the deformation amount of two sides reduce 152mm. The test results have certain directive meaning on rock burst prevention and controlling.
