Mining Wire Rope Manufacturers
Product Advantages:
1. Adopt reverse grouting method, which is simple and convenient, so that the slurry can fill the borehole, realizing the combination of anchor injection and avoiding repeated construction.
2. Combining the advantages of ordinary anchor cable and grouting, it realizes about 40% increase in strength of the new rock body by the way of anchor injection and gluing surrounding rock, thus improving the self-control support ability of surrounding rock.
3. The steel strand is processed with prestressed spiral ribs, compared with ordinary smooth strand, the experiment shows that the anchorage force of prestressed spiral rib steel wire anchors is greatly increased.
Product Description:
Mining anchor cable by drilling holes through the weak rock layer or sliding surface, one end of the anchor in the hard rock layer, and then in the other free end for tensioning and thus exert pressure on the rock layer on the unstable rock body for anchoring. Mining anchor cable is used in coal mines or other mines, shafts and alleys, perimeter rock plus circle, mine shafts to the form and parameters of anchor support according to conventional design, often can not be effective support, resulting in the overall collapse of the anchor support, bringing serious consequences. As the length of the steel hinged wire is not restricted, the anchor circle section can be anchored in the hard top plate, at the same time, because of the steel hinged wire strength level is higher, can provide a larger prestressing force, so that the anchor group section of the lower part of the composite roof joint one, forming a unified rigid roof, play a better support effect.

The structural features include the following:
1. Drilling through weak rock layers or sliding surfaces: the product is drilled through weak rock layers or sliding surfaces in order to realize the fixation and support of the rock body.
2 One end anchored in hard rock formation: One end of the product is fixed in hard rock formation to ensure firm and stable anchoring to provide support for the whole structure.
3. The other free end is tensioned: the other free end of the product is tensioned to exert pressure on the rock formation by applying tension, thus enhancing the stability and load-bearing capacity of the rock body.
4. Used for anchoring unstable rock body: The product is mainly designed for anchoring unstable rock body to strengthen the support and stability of the rock body through fixing and tensioning effect, so as to ensure the safety and reliability of the project.
