Abstract: There has been a proliferation of dynamic bolts and their testing for support based on laboratory testing and field testing. The advantage of the laboratory testing is that the boundary conditions such as the precision of the hole, the stiffness of the ‘rock’ and the quality of the grout/resin installation can be controlled. The field tests are valuable so long as the boundary conditions affecting the bolt response are well understood. However, the industry is silent on how to take the test results and apply them in the ground pertaining to an operation. This paper will show that not only can the laboratory results be readily simulated using wellestablished geomechanical relationships applied to the known boundary conditions, but with an understanding of the inputs, the field conditions can be replicated showing the likely support response. 
Design can then follow for operations with more certainty.
