Rock bolting is a technique used in mining and other applications to stabilize rock formations and prevent collapses using rock bolts.
Rock bolts, are steel rod inserted in a hole drilled into the roof or walls of a rock formation to provide support to the roof or sides of the cavity (Rock Bolt | Reinforcement, Anchoring & Stability | Britannica, 2025).
Holes are first drilled at specific angles, and steel bolts are inserted. These bolts are then secured either by grouting (with cement or resin) or by mechanical anchors. Finally, the bolts are tensioned to compress and hold the rock layers together, enhancing stability.
Here are a few ways in which rock bolting is important:
- In construction projects like tunnels, dams, and underground excavations, rock bolting improves the overall stability of the structure by reinforcing the surrounding rock.
- Compared to other support systems, rock bolting is relatively inexpensive and easy to install, making it a preferred choice for stabilizing rock masses.
- By securing loose or potentially unstable rocks, rock bolts reduce the risk of rock falls in tunnels, mines, or slopes.
By using rock bolting, engineers can ensure safer working environments and enhance the longevity and functionality of infrastructure projects (What Is the Purpose of Rock Bolting? Application and Use of Rock Bolt Support-LANHI Equipment, n.d.).
