A simple model of blasting seismic wave propagation in weak layers is presented according to the characteristics of geological structural faults. The decay rules and formula of blasting seismic wave propagation in weak layers are obtained by using the viscoelastic theory. The decay effects of the blasting seismic wave are investigated with the frequency of seismic loading and parameters of structural faults.
