NMX Dynamic is a high-performance dynamic rock bolt suitable for rock reinforcement in stress conditions.
NMX Dynamic 2.0
Our in-house developed dynamic rock bolt, NMX Dynamic 2.0, has a long, dynamic function sleeve which extends all the way to the thread.
The dynamic function sleeve gives the bolt an energy-absorbing capacity even near the rock face, which relieves the bolt’s thread.
The compressed anchors on the sleeve also mean that the bolt can initially be subjected to static loading even in its outer part before the dynamic characteristics come into play. The bolt’s total energy-absorbing capacity is increased by this function.

NMX Static is a proven solution that has been used in Sweden's underground mines for over 40 years.
