Summary:The invention relates to an electrical resistivity correcting method for a mine transient electromagnetic method. The method includes 1, placing an emitting coil at a measurement point position, setting a transmit-receive distance as TR1, acquiring a primary field value as indicated in the description and a secondary field value containing mutual inductance electro-dynamic potential as indicated in the description through instrument data collection; 2, keeping the position of the emitting coil unchanged, increasing the transmit-receive distance to TR2, acquiring primary field value as indicated in the description and a secondary field value containing mutual inductance electro-dynamic potential as indicated in the description through instrument data collection; 3, putting collected data into a correction formula as indicated in the description for cancelling the mutual inductance electro-dynamic potential, and obtaining a ground secondary field signal V2; 4, performing whole-area apparent resistivity calculat
