Swellex / Split Set. The Swellex / Split Set bolt model (also called Frictional bolts or Shear bolts) in RS2 works as follows:. The entire bolt behaves as a single element. For purposes of the algorithm, the bolt is discretized according to the intersections with the finite elements, however, the behaviour of each segment of the bolt has a direct effect on adjacent segments.

Rock Bolting Systems. Rock bolting systems are used to stabilize excavated rock mass in underground mines and tunnelling. Rock bolts are systematically arranged to transfer the load from the unstable surface or exterior of the rock, to the much stronger interior part of the rock. The rock mass can be reinforced by different types of rock bolts.
