The utility model discloses a compression-resistant wear-resistant tensile cable for a thin seam coal mining machine in the technical field of cables, which comprises an outer protective sleeve, an armor layer is inserted into the inner wall of the outer protective sleeve, a corrosion-resistant layer is inserted into the inner wall of the armor layer, a compression-resistant ring is arranged in the middle of an inner cavity of the corrosion-resistant layer, and supporting convex plates are arranged on the periphery of the compression-resistant ring. An outer cable is arranged between every twosupporting protruding plates, the outer surface of each outer cable is sleeved with an insulating sleeve, hemp rope filler is arranged between every two supporting protruding plates, a plurality of sets of corrugated grooves are formed in the outer surface of the outer protection sleeve, and a plurality of sets of wear-resisting rings are arranged on the outer surface of the outer protection sleeve. A connecting plate is arranged on the front end face of each set of wear-resisting rings, a bolt fastener is arranged on each connecting plate, a plurality of connecting rods are arranged betweeneach set of wear-resisting rings, internal cable cores are separated, and the situation that the cable cores are extruded together when extruded, and consequently the cable is damaged can be avoided.
