Industry & Occupation
Classification
Summary
Worker at a quarry who uses thermal splitting (thermal cutting) technology with flames to split rocks and extract and transport stone materials.
Description
Thermal cutters are professionals in quarries who use oxy-fuel burners to heat the bedrock surface to high temperatures and master thermal splitting (thermal cutting) techniques that create cracks via thermal stress from cooling to split and extract stone materials. After splitting, they transport the stone using cranes or forklifts and conduct dimension checks and quality inspections. The work involves handling high-temperature equipment and moving heavy objects, necessitating thorough safety and hygiene management. On site, emphasis is placed on teamwork while precise operations based on work plans are essential.
Future Outlook
While steady demand is anticipated due to infrastructure development and construction needs, the work structure is expected to change with advances in mechanization and automation. The aging of skilled workers is progressing, posing challenges for technology succession.
