Abstract: To solve the difficult problem of normal implementation of mine transient electromagnetic detection under the influence of 5G mobile communication systems （servers,substations,power supplies,signal antennas,optical cables） and other equipment,the influence degree of 5G equipment,signals,cables,etc.on transient electromagnetic data collection is studied,and their influence range on transient electromagnetic is determined.The results indicate that during the transient electromagnetic detection process,the coil is detected more than 1 m away from the 5G base station,more than 1.1 m away from the 5G antenna,and more than 2 m away from the 5G cable,and the transient electromagnetic signal is basically not affected by it.Taking the 9-806 working face of Pangpangta Mine as an example,transient electromagnetic detection is carried out,and the practice shows that the detection effect is good after excluding the influence of 5G mobile communication system.
