In this paper, discussion was made on the transient electromagnetic prospecting technology by taking a project that was prospected by using the transient electromagnetic method in Pingdingshan Western Mining Area as an example, estimation was carried out on the limit depth of the transient electromagnetic prospecting by using the late transient electromagnetic response, and the prospecting of water abundance of a deep seam's roof and floor aquifers in a north-China coal field was completed by using the high-performance prospecting system, selecting the rational device and parameters and through the prospecting depth test. The anomaly with depth up to 1000m or more was successfully prospected by using this transient electromagnetic prospecting technology. In addition, the feasibility of using the transient electromagnetic method for prospecting the abnormal water abundance area was discussed by the project examples prospected with the transient electromagnetic method, this thus provided the basis for the deep mine water prevention and control.
