Detection system and correction method for mine transient electromagnetism

The invention discloses a detection system for mine transient electromagnetism. The system is arranged in a coal seam and comprises a receiving coil, a transmitting coil, a transient electromagnetic host and a server terminal arranged in a control room. The output end of the receiving coil and the output end of the transmitting coil are connected with the input end and the output end of the transient electromagnetic host respectively. The signal output end of the transient electromagnetic host is connected to the server terminal, and the server terminal monitors and receives the magnetic field force of the transmitting coil by receiving the current output by the transient electromagnetic host so as to obtain transient electromagnetic data in the mine. The invention further discloses a correction method for mine transient electromagnetic detection. By adopting the technical scheme, apparent resistance conversion is carried out by utilizing a corrected transient electromagnetic signal, and a water-rich area of
