A rock bolt device with replaceable head is provided comprised of an enhanced rock bolt assembly for ground support in mining and tunneling, designed to address bolt head damage, mesh displacement, and repair complexities while ensuring continuous structural stability and safety. The assembly comprises a threaded bolt shaft, a bolt head, a face plate, a wire mesh, and a flange that secures the plate and mesh. The face plate distributes load evenly across the rock surface, stabilizing loose rock, while the mesh, positioned behind the plate, remains tensioned and securely clamped, preventing sagging or dislodgement even in case of bolt head failure. The flange, serving as a secondary anchoring point, incorporates a calibrated weak point designed to fail cleanly upon impact, enabling bolt head detachment without damaging the bolt shaft or plate. The bolt head can be replaced by re-engaging fasteners, simplifying repairs and reducing costs.
