Description
Stone selection workers target raw stones or cut stones at quarries or stone processing factories, inspecting for cracks, defects, and variations in color and pattern through visual checks or tapping with a hammer, and classifying and sorting them according to quality, use, and grade. Stones after grading proceed to subsequent processes such as polishing and installation. The work involves handling heavy objects frequently, including transportation using cranes or forklifts, and cleaning the work area. Accurate judgment, attention to detail, and physical stamina are required.
Future Outlook
Demand for stone as construction material is stable, but automation and mechanization of the sorting process is expected to advance. Skilled workers' judgment skills remain important, and adaptation to machine operation and quality control tasks will be required in the future.
