Specializes in mining and extracting Oya stone, handling everything from quality control to transportation as a quarry artisan.
Description
Oya stone extractors are specialists who mine and cut Oya stone, a type of tuff, at quarries including the Oya area in Utsunomiya City, Tochigi Prefecture. At the quarries, they use drills and wire saws to split the stone, and load it out using cranes and forklifts. They also handle stone quality inspections and dimension measurements to maintain quality, safety management, and small-scale blasting using explosives. Knowledge of heavy machinery operation, on-site surveying, maintenance, and geological surveys is required, and teamwork is essential.
