The application and study of the downhole transient electromagnetic method remain very insufficient in China. In order to demonstrate the effectiveness of this method and further promote its application under the situation of increasing exploration depth, the authors chose the Huangshanling ore district in Anhui Province and the Tonglushan ore district in Hubei Province as the study areas. As a result, a good anomaly related to blind ore body beside the well was found in Huangshanling, and the extension of the ore body at the depth of 18200 m was detected in Tonglushan. The two instances demonstrate that this method can detect blind ore bodies and trace the extension of the ore body. Therefore, this method is worthy of promption for deep exploration in China.
