Aiming at 14202 auxiliary roadway of Majialiang Mineinfluenced by the mining dynamic pressure on adjacent working face， the top floor close to close， the multi-form reinforcement and supporting measures being adopted， the large deformation of the roadway has not been effectively controlled. By analyzing the structure of the "lower short cantilever beam and the upper long masonry beam" and the distribution law of the side abutment pressure and the moving abutment pressure of the working face， the strong abutment pressure( large intensity and wide range ) caused by the collapse of the hard roof is the fundamental cause of the continuous large deformation of the existing roadway under the condition of 19.5 m coal pillar. The industrial test shows thatthe surrounding rock control technology combined with the advanced roof hydraulic fracturing with yielding support， the maximum displacement of sides about 0.6 m， the average displacement about 0.4 m， the average heave amount about 1.0 m， effectively controlls the large deformation of the dynamic pressure roadway.
