摘要

Since the 1950s, the induced polarization （IP） method has been widely used in geological surveys, engineering geology, hydrogeology, hazard geology and deep oil and gas exploration, and has achieved ideal effects. However, due to the limitation of equipment performance and power sup- ply, the effective detection depth of the IP method seems to stay at 500 m, and electric response of geological bodies below 500 m can not be accurately obtained. This paper discusses the shock electrical sounding unipolar-dipole work device- the quasi-seismic observation system echosounding technology, which is characterized by large detecting depth, good sounding effect and high efficiency. These advantages just meet the need of the current geological prospecting. Taking a Pb-Zn-Ag-polymetallic ore district as an example, this paper studies the field work method of this sounding technique and its characteristics, and makes an analysis and summary of its application results in combination with geological understanding.
