type of inflatable rock bolt, called the Swellex, was in-vented in the 1980s (Wijk and Skogberg 1982). A few other types of inflatable rock bolts have appeared on the market in recent years, for example, the Omega (Player et al. 2009) and the EX300 ERB (Bjurholt 2007). Inflatable rock bolts have been used for rock support, particularly in

For grouted rock bolts like rebar, all the three components of strength exist at the bolt interface. However, for the fully frictionally coupled bolt, the "Split set" bolt, only a friction component exists at the bolt interface. For Swellex bolts, mechanical interlock and friction comprise the strength of the interface. 3.
Description, Use & method of Installation of Swellex rock bolt for
Energy absorbing rockbolts, designed for applications in high stress environments requiring high deformation and energy absorption capacity such as squeezing, rock burst and seismicity prone excavations. Quasi-static rockbolts, designed for quasi-static loading conditions such as gravity induced ground movement.
