For the problem that the large section coal roadway is used in Majialing coal mine influenced by mining dynamic pressure of adjacent working face deformed and damaged seriously ,the method of numerical simulation and field measurement are used to analyze the deformation rule and the distribute law of stress and plastic zone of surrounding rock with different roadway width. Then the cooperative control technology of surrounding rock is put forward.
