According to the application of KGR-1B anti-jamming electro-detecting in Inner Mongolia graphite ore deposit, the application technology of new anti-interference method was summarized and generalized, the application effect of the electrical method meter was assessed. The exploration result showed that in graphite area, KGR-1B anti-jamming electro-detecting can collect reliable data, distinguish the size of the polarization. It solved the difficulty that the traditional electrical apparatus cannot collect polarizability in graphite area and filled the void of geological data for this area.
