Our Cable Bolting service provides a robust and reliable solution for achieving deep-seated rock mass reinforcement and ensuring effective long-term stabilization in a variety of challenging geotechnical environments, including mines, tunnels, and natural or engineered slopes. This technique involves the installation of high-tensile steel cable bolts, which are significantly longer and possess higher load-bearing capacities compared to conventional rock bolts. These cable bolts penetrate deep into the rock mass, anchoring stable ground beyond potential failure planes and providing substantial resistance against large-scale rock movement and instability over extended periods.

The application of cable bolts is particularly critical in situations where the rock mass exhibits complex geological structures, is subjected to significant stress regimes, or requires long-term support to maintain the integrity of underground excavations or surface slopes. In mining operations, cable bolts are extensively used to reinforce mine roofs, sidewalls, and pillars in large underground openings, enhancing safety and enabling the extraction of ore in a controlled and stable environment. Similarly, in tunneling projects, cable bolts provide crucial support to the tunnel crown and walls, particularly in areas with weak or fractured rock, ensuring the long-term stability of the underground passage. For slope stabilization, cable bolts are employed to anchor potentially unstable rock blocks or soil masses to more competent underlying strata, preventing landslides and ensuring the safety of infrastructure and personnel located on or below the slope.

Our experienced drilling crews utilize specialized drilling equipment capable of installing long, accurately aligned boreholes to the required depths. Following the drilling process, high-tensile steel cables, often with specialized end anchors or grout bulbs to enhance pull-out resistance, are inserted into the boreholes. The cables are then typically grouted along their entire length using cementitious grout, creating a strong and durable bond between the cable and the surrounding rock mass. This fully grouted system ensures effective load transfer and provides long-term corrosion protection to the steel cable.

The design of cable bolting patterns and the selection of cable bolt specifications (length, diameter, tensile strength, and anchoring mechanisms) are based on thorough geotechnical investigations, detailed stability analyses, and consideration of the specific loading conditions and long-term performance requirements of the project. Our team of geotechnical engineers works closely with clients to develop customized cable bolting solutions that address the unique challenges of each site. Our commitment to quality materials, precise installation techniques, and adherence to stringent safety protocols ensures that our Cable Bolting service provides a reliable and effective means of achieving deep-seated rock mass reinforcement and long-term stability for critical infrastructure and mining operations.
