Abstract Interaction of expressway and underlying mine goafs is discussed in detail，including the response characteristics of expressway under mining，the reactivation mechanism of goafs，the numerical simulation of subsidence and deformation at different engineering conditions. Firstly，the basic developing laws of ground movement and deformation at different spatial relationships between expressway and goafs are analyzed briefly. Then，the characteristics of goafs under different mining methods，characteristics of ground deformation and failure，reactivation mechanism and stability assessing methods are analyzed. Lastly，several laws of residual subsidence and deformation characteristics under different working conditions are summarized and compared. The important effect factors are taken into account when using finite element method，such as expressway，goafs，mining characteristics，treating methods，etc. Especially，the complicated geological and mining conditions with this problem are analyzed，including different mining depths and mining thicknesses，seam inclination，multi-mining，adjacent mining，spatial relationships between different seams，etc. The results can provide reference for expressway planning，line selection and mine goafs treatment.
