The applications of numerical simulation in demolition blasting were reviewed. Several methods of numerical simulation in demolition blasting were introduced. The strength and weakness of the numerical methods mentioned in this paper were also indicated，respectively. Furthermore，the solid lattice model in the frame of discrete element method（DEM），which was developed by the author and his team，was detailed described. The existed problems in the current numerical simulation methods of demolition blasting were presented and the future trend of the numerical simulation is finally prospected.
