Optimal rock drills for PROBE DRILLING AND EXPLORATION

PROBE DRILLING 

Probe drilling is commonly used in tunnel boring machines (TBM) to construct tunnels, passages and shafts. Rock drills are used to investigate the ground conditions that stand ahead of the excavation so that geotechnical design conventions can be confirmed. 

In probe drilling, drill holes can be over 60 m deep; continuous drilling is essential. World widely used Doofor models DF550L and DF560L have established sustainable processes in TBM’s choice for probe drilling. Platform-independent design in DF550L/DF560L helps TBM manufacturers plan various solutions in their feed systems.
