Industry & Occupation
Classification
Summary
Specialized occupation at dam and tunnel construction sites that excavates bedrock using methods such as drilling, face advancing, and blasting to advance the tunnel.
Description
Advance excavators in tunnel and dam construction perform drill holing, face advancing, and blasting operations to excavate bedrock and advance the tunnel. Based on excavation plans and geological conditions for method selection, they operate excavation machinery, remove crushed rock, conduct underground surveying, and thoroughly manage safety. Those with blaster qualifications handle explosive charging as well as the installation and management of detonators. The work environment is confined and high-humidity with significant vibrations and noise, requiring teamwork to perform tasks accurately and efficiently. Regular machinery inspections and maintenance are also key responsibilities.
Future Outlook
Stable job openings are expected due to social infrastructure development and demand for updating aging tunnels and dams. However, advances in mechanization and automation, such as shield machines, are leading to a trend where machine operation skills and remote operation capabilities using IT are required.
