Abstract Taking the deep mining roadway in Jisan coal mine as the research object，the deformation and failure mechanisms of surrounding rock，and the principle and application effect of anti-scouring and releasing energy coupling support technology were studied by combining theoretical analysis，numerical simulation and laboratory test to solve the problems of large deformation of the surrounding rock and easy failure of the support body in deep mining roadway. The results show that large deformation and impact of deep mining roadway in Jisan mining area own to the complex high stress field and its superposition，which make the roof of thick hard sandstone easily accumulate energy. Comparing with the traditional support system which cannot effectively absorb and transform the residual energy of the surrounding rock，the constant resistance large deformation support system can absorb more energy(DF?x) and realize the controlled release of the shape energy of the surrounding rock due to that the constant resistance value(F) and the deformation quantity( ) can be designed independently，which solves the problems of high prestressing force difficult to apply，easy to break and quantitative anti-scour design in the anti-scour support system. The field application results show that the deformation and the advance influence range of the surrounding rock of the constant resistance support are respectively reduced by about 40% and 33% compared with the original support. The research results can provide a reference for similar deep mining roadway support design with an impact tendency.

Key words： mining engineering deep mining failure mechanism constant resistance large deformation anti-erosion and energy release
