Based on small anchor length, low anchor force, which cannot effectively resist passing of surrounding rock of deep pressure and was unable to control the deformation of roadway. By adopting extended anchor cable instead of bolt, acting point deepened 4 m into acting point to increase the two sides of roadway surrounding rock reinforcement circle, thickness and the support strength, effectively control the deformation of roadway. Arch roof section was adopted, under the anchor rope (rod) support, rock mass was formed to a uniform compression arch. Compression arch rock and tangential were in compressive, in a three-dimensional stress state, the strength of the surrounding rock was increased and so was supporting capacity.
