Industry & Occupation
Classification
Summary
Technical job operating large tunnel boring machines (TBM) to perform stable and safe excavation in tunnel construction using the shield method.
Description
Large tunnel boring machine operators are specialist technicians who excavate underground tunnels using shield machines (TBM). They manage the rotation speed of the cutter head, thrust force, and earth pressure to maintain stability of the excavation face. They handle operations from the machine control panel, inspections and adjustments of hydraulic systems and conveyors, and management of ventilation and muck removal systems. They respond quickly to any abnormalities due to geological changes or machine troubles. They collaborate with on-site engineers and construction managers, adhering to safety management standards while proceeding with the work.
Future Outlook
With the demand for infrastructure renewal and underground space development, the demand for TBM operators will remain stable. The introduction of remote operation and automation technologies will advance, requiring higher levels of machine control technology.
