Abstract: In order to solve of No.15 coal seam working face roadway the long -term support excess problem,ease the tight mining to succeed.This at the end of the 15101 working face in phases retracement channel in the process of roadway bolt support technique is studied,put forward by optimizing the supporting parameters of roadway surrounding rock control scheme.Based on the theory of suspen-sion and FLAC 3D software,optimize the roadway supporting parameters and the supporting technology.The results showed that the retreat roadway supporting parameters optimized,amount of roof abscission layer is 20 ~33 mm,coal wall lateral nearly 19 ~25 mm,supporting material consumption reduced by 32%,ahead of working face 9 d to complete the move.The reliability of the roof management has greatly promoted,face retracement is attained safety,saving and speed effect.
