DYNA® Tork Bolt is designed with a spiral mixing blade to ensure ultimate mixing of DSI Underground resin in the borehole. This blade design has a dual propose: to mix the resin properly and provide anchorage for static ground support. The cone is designed to yield and transfer dynamic loads into the resin in rock burst conditions, absorbing the energy through controlled deformation.
This ploughing effect through the resin will ensure that most of the kinetic energy in a rock burst is contained within the rock-mass. The DYNA® Tork Bolt is the ultimate Dynamic Rock Support Solution for deep mining where it provides proper anchorage in a regular static mining environment, and ultimately yielding support in dynamic rock burst conditions.
