Abstract This paper presents the principle and characteristics of transient electromagnetic longitudinal conductivity differential imaging and the processes of the software for longitudinal conductivity differential imaging to process the transient electromagnetic data. Experimental exploration was carried out in some coal mines in Henan Province. The low resistivity area was inferred and delineated, and the method was compared with the traditional method of apparent resistivity imaging. The results indicate that the software used in this study has the features of faster processing speed, intuitive imaging, higher interpretation accuracy.
