The invention provides a mining signal cable. According to the mining signal cable, each core wire is composed of extruded insulated layers outside a conductor, two or more core wires are hinged, drainage wire sets, cooper strip shielding layer sets, isolating layer sets and braided shielding layer sets are arranged in sequence to form cable core sets, a main cable core is formed by hinging the cable core sets, a water blocking packing layer is arranged in the clearance of the main cable core, and an isolating layer, a drainage wire, a copper strip shielding layer, an inner protective sleeve, a flame resistant layer, a braided shielding layer, a water blocking layer and an outer protective sleeve are arranged outside the main cable core in sequence. The mining signal cable has the properties of being dampproof, waterproof and resistant to fire and resisting electromagnetic waves, and is especially suitable for the signal transmission of various mines with complex work environments.
