In order to obtain support effect in underground roadway and its deformation features, deformation and activities of underground roadway were monitored and its observed data was analyzed reasonabley, which showed that surrounding rock and surrounding rock loose circle were controlled effectively, the displacement of two sides became very small and range of loose circle was only 2 m; The stress of anchor cable was no longer increased suddenly, but the force was very uniform, which meant that strengthening of two sides and roof had good effect after support. It was clear that new support scheme was rational, support effect was obvious and supporting test in field was successful.
