Abstract：In order to solve the control problem of dynamic impact phenomena in roadways with high stresses，and to clarify its occurrence law and the control mechanism of the surrounding rock，a physical simulation test system for dynamic impact phenomena in deep roadways of coal mines is developed. It includes balanced loading device，boundary energy storage device and multi-source monitoring platform，which can achieve high stress equilibrium loading of the model body and instantaneous compensation of boundary stress. Therefore，the stress environment before and after the occurrence of dynamic impact phenomena in deep roadways is effectively simulated by this system. On the basis，a series of physical simulation comparative tests on dynamic impact phenomena in deep roadways are carried out with a typical deep high stress mines as simulation object combined with the developed high-strength energy absorbing support material. It reproduces the entire occurring process of dynamic impact phenomena in models with different types of support parameters. The dynamic failure mode，stress-displacement evolution law of surrounding rock in different parts of the roadway are analyzed. Meanwhile，the interaction and impact response characteristics between different support materials and surrounding rock are clarified. The control advantages of energy absorption in the dynamic impact phenomenon of deep roadways by the new energy absorption support material are revealed. The average deformation of the surrounding rock decreases by 36.9% though the application of this support material as the dynamic impact phenomenon occurs. According to the test results，further research is conducted on the field application of energy absorption support，which effectively reduces the risk of dynamic impact phenomena in deep roadways and ensures the safety of surrounding rock throughout the roadway operation cycle.
