An apparatus includes a current excitation source, a roadheader telescopic protection cylinder, an electric rotating apparatus, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protective housing, an optical fiber ring, an optical fiber current sensor control unit and a recovery electrode. The apparatus transmits an auxiliary current Iand a monitoring current Ito a coal seam. The auxiliary current Iand the monitoring current Iare homologous currents that are incompatible, and the auxiliary current Isqueezes the monitoring current I, so the monitoring current Imonitors the environment of the coal seam. The monitoring current Iflows to the coal seam as, and a return current Iflows through the transmission shaft and a roadheader expansion part. The optical fiber ring measures the return current I, when the roadheader is heading forward and encounters abnormal geological bodies.
