Cable Bolt

Mono-strand Cable Bolt. We provide two types, they are bulbs cable bolt and expansion shell cable bolt.

 

A cable bolt is a type of reinforcement element used in mining and civil engineering applications. It is a long, high-strength steel cable that is installed into rock or soil formations to provide additional support and stability.

 

The installation process typically involves drilling a hole into the rock or soil and then inserting the cable bolt into the hole. The cable bolt is often grouted or cemented into place to provide increased anchorage and load transfer capabilities. The grout or cement surrounding the cable helps distribute the load to the surrounding rock or soil, reinforcing the ground and reducing the risk of failure or collapse.

 

Cable bolts are available in various diameters and tensile strengths to accommodate different project requirements. They can be tensioned to apply a pre-stress load, which further enhances their capacity to resist ground movement and stabilize the surrounding rock or soil.

 

Cable Bolt Advantages

Cable bolt offers several advantages in mining and civil engineering applications. Here are some key advantages of using cable bolts:

 

Ground Reinforcement: Grouted cable bolts provide effective reinforcement of weak or unstable ground conditions. They improve the load-bearing capacity and stability of rock masses, slopes, and soil formations, reducing the risk of ground failure or collapse.

 

Flexibility: Cable bolt can be installed in various orientations and configurations, allowing flexibility in design and application. They can be used in combination with other ground support systems, such as rock bolts or mesh, to provide a comprehensive reinforcement solution tailored to specific project requirements.

 

High Load-Carrying Capacity: Cable bolt is made of high-strength steel, which gives them a significant load-carrying capacity. They can resist high tensile forces and transfer loads effectively, providing robust support to the ground and structures.

 

Tensioning Capability: Cable bolt can be tensioned during installation, applying a pre-stress load to the ground. This pre-stress helps to control and limit ground movement, reducing the potential for instability. Tensioning also improves the overall performance and load distribution of the cable bolt system.

 

Versatility: Cable bolts are versatile and can be used in a wide range of applications. They are commonly employed in underground mining operations, tunneling projects, slope stabilization, excavations, and other scenarios where ground reinforcement is required.

 

Cost-Effectiveness: Cable bolt offers a cost-effective solution for ground reinforcement compared to alternative methods. They can be installed quickly and efficiently, reducing construction time and associated costs. Additionally, cable bolts require minimal maintenance once installed, resulting in long-term cost savings.

 

Monitoring Capabilities: Cable bolts for mining can be equipped with monitoring devices, such as load cells or strain gauges, to measure and monitor the load distribution and behavior of the ground. This allows for continuous assessment of the ground conditions and early detection of potential issues.

 

USE

The primary purpose of a cable bolt is to enhance the structural integrity of the rock mass or soil and prevent or control ground movement. It is commonly employed in scenarios where the surrounding rock or soil is weak or prone to instability, such as in underground mines, tunnels, slopes, and excavations.
