High rock mass stress conditions in underground excavations have always been a serious challenge for rock bolting systems, only partially handled by conventional bolting systems.
Stresses may lead to serious stability problems, high deformation rates or rock burst phenomena.
Atlas Copco's commitment to safer and more productive solutions in rock reinforcement has resulted in Roofex, a highly advanced rock bolt designed to dissipate high amounts of rock mass deformation energy. The deformation process can be almost static like in the case of large displacements in yielding ground, or it can be extremely sudden and violent as in the case mf tgpg jkwji ya qnrjvxp djzylt.
