Coal mine TBM electrical method advanced geological forecasting system and method

The invention relates to a coal mine TBM electrical method advanced geological forecasting system and method. According to the scheme, the system comprises a detection host, an emission electrode used for being electrically connected with a cutterhead, a cutterhead measuring electrode used for being electrically connected with the cutterhead, a cave wall measuring electrode used for being electrically connected with a tunnel cave wall, and a backflow electrode used for being electrically connected with the tunnel cave wall. The backflow electrode is arranged in the direction, far away from the cutterhead, of the hole wall measuring electrode; the detection host is connected with the emission electrode, the backflow electrode, the cutterhead measuring electrode and the hole wall measuring electrode; the emission electrode is used for emitting main current to a tunnel face through the cutter head, and the backflow electrode is used for receiving the main current conducted through the ground; the cutterhead meas
