Stone Splitter

Industry & Occupation
Classification
Summary
A craftsman or worker who specializes in splitting large rocks or ores into small pieces using hand tools or machine tools at mining sites or stone processing plants.
Description
Stone splitters use hand tools (hammers, chisels, wedges), drilling machines, and sometimes machine tools to break down large rocks or ores mined at quarries or mines into smaller pieces. They first drill holes in the area to be split, insert wedges to induce cracks, and divide them into small blocks according to specified shapes and dimensions. Accuracy in splitting and ensuring work safety require understanding the properties of the stone material, tool handling skills, and proper use of protective equipment. On-site, coordination with crane or forklift transport operations is also necessary.
Future Outlook
While demand for aggregates for construction and civil engineering is stable, there are concerns about a shortage of workers due to advancing mechanization and the aging of practitioners.
