Abstract: Based on the laboratory test results of the physics and mechanics properties of surrounding rock of －960m north wing C13 track roadway,by using the Flac^3D simulation software to analyze the soft rock roadway surrounding rock deformation properties in deep mine.The research shows that the deformation of the two sidewalls and the floor heave are the main deformation of soft rock roadway in deep mine,the stability of roadway floor is the key of the surrounding rock control.The new supporting scheme put forward strengthening the early support strength,increase the angle of the floor anchor,increase the intensity of the bolt and apply the full-face grouting technology.Field application show that the supporting scheme for soft rock roadway in deep mine is feasible.
