With the exhaustion of coal resources day by day, the depth of coal mining has being increased year by year. As a result of high-stress, surrounding rock of deep roadway was serious deformation. Support of deep roadway was the key and emphasis of support in coal pressure field. In this paper, an effective support scheme was worked out on the basis of engineering practice including the effective designing scheme. The use of anchoring cables and bolt plus grouting in whole face of roadway, timely monitoring of mine pressure were adopted. Results of this experiment indicated that this support scheme exerted effect for controlling surrounding rock in deep roadway, and provided guidance for controlling surrounding rock in deep roadway.
