Split set is also know as friction bolt.
It is a rock support method used in underground mining and tunnel construction.The bolt consists of a high strength steel bolt with a ''U'' shape cross section and a longitudinal groove.
To install a Split Set bolt, a hole is made in the rock with a diameter slightly smaller than the bolt’s diameter, and the Split Set is inserted into it. As the bolt is pushed into the rock, the “U” shaped cross-section reduces and adjusts to the shape of the borehole. This expansion creates friction between the Split Set and the surrounding rock along its entire length, providing strong resistance to displacement
