We evaluated the problems and limitations of existing seismic source, and innovatively applied wire electrical explosion controllable shock wave technology to seismic exploration. The technology and principle of the controllable shockwave produced by wire electrical explosion are analyzed. Moreover, presenting the characteristics of wire electric explosioncontrolled shock wave technology as a seismic exploration source and the field excitation tests in the Shanbei desert, the feasibility of wire electrical explosion shock wave technology as a source technology is verified theoretically and experimentally.Based on the quantitative analysis of the acquired data, we believe that the controllable shock wave technique can be used asa new seismic source technique in the field of coalfield seismic exploration in the Shanbei desert. Finally, the existing problems in the experiment are summarized, which provides the direction for further improvement.
