The invention provides a dynamic monitoring and sensing system and method for a metal mine deep stratum temperature field. The system comprises a temperature probe, a signal transmission cable, a positioning connecting rod, a dynamic acquisition instrument and an optical fiber transceiver, the positioning connecting rods are arranged in temperature monitoring drill holes of a target roadway; the temperature probes are arranged on the positioning connecting rod at set intervals; each temperature probe is connected with one end of the signal transmission cable; the other end of the signal transmission cable is connected with the dynamic acquisition instrument; the optical fiber transceiver is respectively connected with the dynamic acquisition instrument and the ring network switch under the mine; and the optical fiber transceiver is used for transmitting the temperature data acquired by the temperature probe to the ground in real time. According to the invention, temperature field dynamic monitoring of multipl
