Abstract
The utility model relates to a mining optical cable for laying a vertical shaft. The mining optical cable for laying the vertical shaft includes a central reinforcing member, a plurality of optical fiber units and at least one filling rope which are intertwisted together or arranged in parallel around the central reinforcing member, and a double layer polyester tape, a water-blocking tape, a tearing rope and an inner sheath which are coated at the periphery of the filling rope and the plurality of optical fiber units. The double layer polyester tape is filled with water-blocking cable cream; and each of the optical fiber units includes a loose casing pipe, fiber cores through the inner of the loose casing pipe and fiber cream filled between the loose casing pipe and the fiber cores, and each of the optical fiber units further includes a wrinkle steel tape coated on the tearing rope and arranged in the inner sheath, a steel wire armor coated on the inner sheath and an oversheath coated on the periphery of the steel wire armor. According to the mining optical cable for laying the vertical shaft, the wrinkle steel tapes are added on the tearing rope and among the inner sheaths, and the steel wire armors are added on the inner sheaths, to enable the cable to have a rat proof function, and enhance the tensile strength of the cable.
