Abstract: Aiming at the current situations of the mergers and reorganization process of the group and combining with the group mine own characteristics,stress state problems of mine roadway support are analyzed by theoretical analysis and numerical simulation.The result shows that surrounding rock stress is mainly the compressive stress,the stress value in two sides of roadway and arch foot is comparatively large and prone to stress concentration.The variety of the stress in the surrounding rock mainly centralized in the diameter range of 2 times.The stress of surrounding rock transfers to the roadway after supporting.
