Drill Tech designed and constructed a shaft and shaft station, the headframe and hoist foundations, and starter tunnels on this private energy project for New Era Petroleum’s oil extraction operations. Up to 10′ thick concrete foundations were constructed for the hoists and headframe, as these structures provided shaft access at the surface. Shaft excavation was performed through conventional drill/blast SEM sinking techniques staged from a five-level sinking platform that housed a drill jumbo and a Cryderman mucker. Temporary rock bolt support was installed for the shaft. Drill Tech installed the concrete liner in 20′ lifts from the work deck during sinking, using concrete from a Drill Tech onsite batch plant. The starter tunnels were completed using SEM techniques with jack leg drills and a mini excavator and were supported with rock bolts and shotcrete.
