Summary:The invention relates to a tunnel construction monitoring and rescuing emergency cable. The cable comprises a plurality of conductors, an insulating layer, an inner shielding layer, an outer shielding layer, an inner sheath, an armor protection layer and a jacket, wherein the insulating layer, the inner shielding layer and the outer shielding layer are extruded on the conductors to construct insulating conductor cores; and a cable core consisting of a plurality of insulating conductor cores is provided with the inner sheath, the armor protection layer and the jacket from inside to outside in sequence. The tunnel construction monitoring and rescuing emergency cable has the advantages of reasonable and simple structure, easiness in producing and manufacturing, low cost, high application performance, reliable service life, thermal stability, moisture resistance, superior electrical performance, physical and mechanical performance, high flame resistance, high temperature resistance, no crack of the jacket, capabi
