Expandable Bolts
Expandable bolts are mechanical rock support systems designed to provide immediate anchorage in underground mining, tunneling, and civil engineering applications.
Expandable Rock Bolts for Mechanical Ground Support in Mining and TunnelinG
Expandable bolts are installed inside drilled holes and mechanically expanded to create a secure anchorage against the surrounding rock. They are commonly used in ground support applications where fast installation and immediate load-bearing capacity are required.
These bolts are particularly suitable for temporary or permanent support in stable to moderately fractured ground conditions, offering a practical and efficient reinforcement solution.
