Onaping Depth Shaft
Overview
Drill and blast on two portions of the Onaping Depth shaft, using Cubex and stopemate drills.
Consbec carried out drill and blast work on two portions of the Onaping Depth shaft near Sudbury, working alongside the shaft-sinking contractor.
The shaft is 7 metres in diameter, and we drilled it with Cubex and stopemate rigs. In a shaft, hole accuracy sets the finished profile, and every round is drilled and loaded in a tight vertical space.
