Abstract: Based on the surrounding pressure,shrinkage of whole body,strong deformation characteristics of soft rock in deep roadways,a stress-relief method of active control was established.It was put forward that the expansive deformation energy of surrounding rock would be released,the high stress be transferred to the deeper surrounding rock,and the stress in shallow rock be reduced.Considering the geological conditions of the west tunnel in Guhanshan Mine,the rational space for deformation release was determined.Using high-water rapid hardening materials to reinforce the mudstone easily weakened and expanded by water,the rational time of the secondary support was obtained.The obtained results were successfully applied in the coal mining,and the large deformation of soft rock in deep roadways could be controlled effectively.
