///By studying the double resource mechanism of seismic waves in the near-surface Layers, the paper discusses the relationship of blasting sources between the near-surface layer and borehole depth, and investigated the method that how to select the seismic excited depth of blasting source by using the largest energy and signal-to-noise of the seismic wave. The research of 3-D seismic cases suggested that the double source and Q factor of seismic waves near the near-surface layer would be the most important factor for choosing excited depth of the seismic waves and the examples shows that the method not only achieved high quality results of exploration, but also saved the costs of acquisition.
