A friction bolt assembly has a tubular friction bolt body defining a cavity and having a split. A rod extends through the cavity. An expansion element is mounted on the rod at or toward the rod leading end and protrudes through the friction bolt body leading end. The expansion element has an engagement surface tapering toward the rod trailing end.
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 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.
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 .
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.
Expandable Friction Bolt | Expansion bolt Clean and fast rock bolting solution. GEOTEC Expandable Friction Bolt (Expansion bolt) is a bolt made of a deformed steel tube which is expanded at the end of installation by injecting highpressure water.
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.
