Abstract : It is evident that during propagation of the blast shock wave, a moment occurs when the shock wave emits an elastic wave which in time (calculating that the speed of the elastic wave is constant, whereas the speed of the shock wave decreases with time) increasingly surpasses the shock wave. The ground model and equation which describe ground behavior during blast wave action upon are studied. In initial postulates, all ground parameters are accepted as zero. The given parameters are determined from the system of equations which describes the ground state at the front of the shock wave and products of detonation at the rarefaction wave.
