Abstract：According to explosive theory,the paper analyzed the relation of energy transformed from shock wave into seismic wave when explosion by spherical charge, studied the principle of seismic energy stacked by using multilevel small-charge-sized and vertically delayed sources,which suggested that two-level vertically-delayed time depends on the interval of two-level spherical charges and it must consider the radius of broken zone formed by explosion of one-level spherical charge and the explosion-save distance.Under the condition of reasonable controlling on time of ignition of two-level or multilevel spherical charge,the downgoing energy of seismic wave can be improved and the vibration of surface can be reduced. The experiment of vertically delayed stack source has been implemented by using the results of the theoretical analysis. The results showed that the vertically delayed stack source can increase the frequency of seismicwave in a precondition of ensuring a certain S/N ratio，that is ideal explosive source for high-precision seismic exploratipn.
