Swellex rock bolts are extremely versatile and can be used in various tunneling and mining systems. An application in tunneling is to use 

parameters on the performance of Swellex rock bolts, wherein pull test data was compiied from various mines in North Amenca and Europe.

The bolt is expanded inside the borehole drilled into the excavation wall. The installation process is easy and very similar to other rock bolt installation processes, making Swellex rock bolts accessible to all operators. Classifications: Premium line: The Premium line is a typical tunnelling bolt, with a high yield load and good deformability.

Graduate Department of Civil Engineering, University of Toronto An extensive study was conducted to determine the effets of rock rnass parameters and operational parameters on the performance of Swellex rock bolts, wherein pull test data was compiied from various mines in North Amenca and Europe.

The Swellex rockbolt is a sealed steel tube folded on itself which upon installation is expanded with high water pressure offering strong performance and interaction with rock mass,

Bolts are not released until recommended pressure is reached for a minimum period of time to deliver best performance of the Swellex rock bolt. Swellex HC1-L and EC1-L pumps log installation parameters, providing you with a permanent quality control record for every bolt; monitoring the safety and productivity. Swellex HC1-L and EC1-L pumps can

grouted bolts as well as swellex bolts will mainly be analyzed in the thesis. In the following, four constitutive models developed for the design of rock-bolt system based on analytical methods will be discussed. In is of great importance to utterly acquaint with those models involving the rock-bolts, rock mass interaction. 3.
