摘要（英）：

The invention relates to the technical field of mine laneway supporting, and discloses an anchor cable impact preventing device which comprises a cable body, high-pressure air bags, impact preventing pits and limiting sleeves. The cable body is a steel strand formed by twisting stranded steel wires, the steel strand is opened by a certain length to form the pit-shaped impact preventing pits, the high-pressure air bags are placed in the impact preventing pits, and the limiting sleeves limiting the positions of the high-pressure air bags are arranged on the two sides, in the length direction of the steel strand, of each impact preventing pit respectively. The invention further discloses an anchor cable. The cable body of the anchor cable can be prevented from being broken suddenly, anchor cable supporting is prevented from losing efficacy, wounding accidents are avoided, and safety of laneway supporting is guaranteed.
