The invention discloses an anti-dragging wear-resistant slurry-resistant cable used for a shield machine. A cable core comprises a plurality of conductive wires and a plurality of earth wires. Each conductive wire comprises a first conductor, a first semi-conduction belt, a conductor shielding layer, an insulating layer, an insulating shielding layer, a second semi-conduction belt and a first weaving layer which are successively arranged from inside to outside. Each earth wire comprises a second conductor and a third semi-conduction belt. The plurality of conductive wires are stranded, and the plurality of earth wires are arranged on the periphery of all conductive wires to form the cable core. Gaps of the cable core are filled with elastic filling strips. An inner lining layer covers the cable core, a second weaving layer covers the inner lining layer, aramid yarn is woven to form the second weaving layer, and an outer sheath cover the second weaving layer. The anti-dragging wear-resistant slurry-resistant c
