Shandong with the Swiss mining science and technology limited company in the years of production and construction on the basis of experience, summed up a few improvement scheme of anchor cable construction:

    1 in the use of anchor cable joist, taken in the above way wood batch or sabot, in order to increase the absorption of anchor cable extending deformation, make its narrow and bolt extends between the difference of rate;

    2 should be in a timely manner will bolt pretension, enhances the bearing capacity of the anchor rod. In the face of head-on construction after anchor, to strengthen the support, in order to raise the anchor cable and anchor bolt on the roof load, strengthen the roof support, and played on the roadway.

    3 in the existing geological conditions, the joists liner is in a horizontal state, liner material can adopt hard wood or steel products, in order to reduce the loss of bearing capacity of objective decomposition. In anchor cable construction process of suspension part of wood group, then it is to pave the way, not only can enhance the joists of the surface contact, but also can increase the absorption of deformation, ease the cable elongation low defects, thereby enhancing the bearing strength.

    4 in the gas welding cutting or drilling site welding stiffener, to increase the strength of the position of the guarantee in the construction process, not the joist fracture.

    5 according to the direction of rotation of the drill and the anchor cable steel strand with the overall effect, the effect of anchor, to increase the overall effect. During use, pay attention to cable accessories ( lock, lock ) supporting the use, such as locking plate screwed to the incision.

      Through the above measures of improvement of anchor cable construction of cable supporting system, reasonable structure, convenient construction, ensure the safety and reliability of cable installation.
