Abstract: Under the roadway support of large deformation caused by strong impact，it could be safety when bolt coordinates with anchor cable on anti-rockburst supporting. That kind of support not only relates with the safety during construction，but also influences the long-term safety of roadway support. When bolt and anchor cable union support the roadways with large deformation is used in condition of strong impact，the bolt and anchor cable will be easily destroyed．So the paper introduces the main construction and yield pressure features about the large deformation bolt（anchor cable）suited to the roadways with large deformation caused by strong impact．The coordination of anti-rockburst principle and design criteria of the research about bolt and anchor support has been analyzed at the same time．On the base of experimental research of the large deformation of bolt (anchor cable)，the experimental design method under different impact conditions have been given．Research result has certain reference value to the support design construction of the roadways with large deformation caused by strong impact．

Key words: roadway support, surrounding rock, yield pressure feature, bolt, anchor cable
