What are Rock Bolts? Home Stratosphere

Rock bolts have been used during underground excavation in the mining and tunneling industry for well over 100 years. They provide temporary roof support and also keep walls secure. Today, rock bolts are used in many other applications. These include reinforcing concrete dams, bridge abutments, rock cliffs, steep slopes, and stabilizing road cuts.

Rock bolt Wikipedia

A rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be used in tunnels or rock cuts.It 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 U.S. in the 1920s.
