Holes are drilled from the bottom up to the intersection of the ore body.
This is then used as a transfer pass for dropping material from the reef / ore horizon downwards where it can be collected and transported; or as a ventilation shaft to the mining location.
Drilled upwards, no typical holing point is required.
Personnel are not required to enter the excavation; enhancing safety.
Safer, faster and a lower cost alternative to Alimak excavation.
Drill rods feature a unique non-rotating stabiliser design.
