Tunnels. Slopes . Places where need ground support. How to work. The nature of ground must be evaluated. Choose the proper bit and drill a hole according to bolt diameter,bolt length,and drilling procedure,and length is at least 150mm longer than length of friction bolt. Place a plate onto friction bolt (dome against the ring,tapered end at front).
Friction Bolt is temporary rock reinforcement in Mining and Tunneling. Bonding forces between the friction bolt and the rock mass are caused by form closure and friction transfer between the borehole wall and the rock bolt which is expanded by hydraulic pressure. Main Advantages OMEGABOLT® Expandable Friction Bolt
Nuts and bolts compress the rod and transfer forces into the rock composition, stabilizing it. Friction Rockbolts: Friction bolts work by being driven into predrilled holes that are slightly smaller in diameter than the metal rod or dowel. This creates a strong friction force .

A rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be used in tunnels or rock transfers load from the unstable exterior to the confined (and much stronger) interior of the rock mass. Rock bolts were first used in mining in the 1890s, with systematic use documented at the St Joseph Lead Mine in the in the 1920s.
Underground Mine Roof Support Mine Roof Bolting Every kind of underground mine uses Split Set® friction rock bolts for mining and ground support. Miners use them for mine roof bolting and mine roof support as well as to pin mesh, hang conveyors, hold pipes, and cables, secure rails in place, and for other needs.
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals .

Split Set® Friction Rock Stabilizers (Friction Bolts) Rock Bolts for Reliable Ground Support. Split Set® friction rock stabilizers are manufactured by International Rollforms, Inc. for underground or above ground applications in mines, tunnels, slopes, or wherever reliable ground support is needed.
Several factors can affect the torquetension relationship. These include friction in the threads (affected by thread tolerances, rust, dirt, etc.), friction between the wedge and leaves in the expansion shell (affected by dirt, casting roughness, etc.) and friction between the bolt head (nut) and plate washer (influenced by angularity, rust, rough edges on nuts/plates).
split set rock bolt tubular friction bolt /friction stabilizer a kind of slotted steel tube with one end tapered, the other end welded to hold the bearing plate. It is especially used together with in hardrock mine, tunnels and slopes, etc. Friction rock bolt is inserted slightly .
Split Set® friction rock stabilizers are manufactured by International Rollforms, Inc. for underground or above ground applications in mines, tunnels, slopes, or wherever reliable ground support is needed. Our friction rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over its full contact length immediately upon installation.
