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.
