A split set is a type of rock reinforcement method used to support excavations in rock masses that are prone to instability. It consists of a steel tube split longitudinally, creating a sleeve with a series of prongs. When installed into a borehole, the prongs of the split set expand, exerting pressure against the rock walls and providing support.
The split set method is relatively simple and quick to install compared to other rock support methods, making it popular in mining and tunneling applications where rapid excavation and support are necessary.
