Rock Bolt

Jinnox Bolt is a leading Rock Bolt Manufacturer in india. A rock bolt is a crucial support system used in tunneling, mining, and rock excavation projects to stabilize rock masses. It works by anchoring into the rock and providing reinforcement, preventing potential collapses or displacements. Typically, rock bolts are installed by drilling a hole into the rock, inserting the bolt, and then securing it with mechanical anchors, resin, or cement grout. This method enhances the overall strength of the rock by creating a compressive force that holds fractured rock layers together. Rock bolts come in various types, including mechanical, grouted, and friction bolts, each serving specific geological conditions. Mechanical rock bolts use expansion shells to grip the rock, while grouted bolts rely on cement or resin to bond with the surrounding material. Friction bolts, such as Swellex or Split Set bolts, work by exerting radial pressure against the hole walls. The choice of rock bolt depends on factors like rock type, load-bearing capacity, and environmental conditions such as water presence or seismic activity.
