Cable Bolt:
Cable bolt is composed of high-strength steel wire, barrel & wedge and plate.
The cable bolt support force is relatively large, and it is anchored by grouting, which is suitable for reinforcement of large-section chambers and roadways in underground coal mines.
Usually, cable bolt needs to be prestressed, it is an active force supporting, and can be used as a permanent anchoring project.
The advantages of cable bolt:
1. Cable bolt is made of high-strength steel strands, and its bearing capacity is better than ordinary rock bolt.
2. It can be pre-stressed and actively supported.
3. The anchorage length is better than ordinary rock bolt.
4. Plain or bulbs available.
