In order to study the dynamic instability mechanism of roadway structure under earthquake loading. Engineering structure fluctuation and structure based on the kinetic theory,the establishment of coal mine goaf rock dynamics equation,the small interior similarity calculation of ANSYS finite element numerical shaking table experiment combined with comparative analysis of seismic dynamic,dynamic characteristics of roadway. Study results show,in the arched and circular tunnel geometric center horizontal line of ±45°regions and the arch tunnel at the bottom corner of the shear stress,principal stress is the most significant,while in the two corners and roof arch roadway damage is easy to produce,the roof of a circular tunnel crack,the maximum principal stress of circular tunnel and the distribution of shear stress are shown on the right direction under the earthquake effect. The maximum principal stress of arch roadway is on the right side and the distribution of shear stress and the two corner roof and arched tunnel are easily damaged. Strengthening and anti-seismic measures to the weak strength of the roadway will improve the seismic performance of roadway in the seismic design of roadway.
