Split Sets are passive support elements primarily used in underground excavations, such as tunnels or mining operations, to stabilize the rock mass and prevent collapses. They consist of a steel tube longitudinally slotted in the shape of a "C", allowing them to compress slightly when inserted into a borehole with a diameter slightly smaller than that of the bolt. This compression generates constant pressure along the entire contact surface between the bolt and the borehole walls, creating friction that provides immediate stability to the system.
