Rock bolts are an essential ground support element in rock tunnels, widely used to stabilise and reinforce rock masses by providing active support. They function by transferring the load from the potentially unstable surface or fractured rock to more stable ground, effectively forming a composite structure. In tunnelling, rock bolts are typically installed by drilling holes into the rock and anchoring them using cement grout, resin, or mechanical systems. This ensures that tensile forces are app

Typically consisting of long, threaded steel rods, rock bolts are inserted into pre-drilled holes and anchored into the rock mass using cementitious grout or mechanical anchors. Once installed, rock bolts provide support by redistributing loads and preventing the movement or collapse of unstable rock formations. They effectively increase the overall strengt
