Industry & Occupation
Classification
Summary
Occupation that sorts and concentrates coal or ore mined from mines by particle size or specific gravity to ensure product quality.
Description
Coal preparation workers remove unnecessary materials through processes such as particle size classification using screens, specific gravity separation by gravity selection or flotation, and heavy liquid processing after transporting coal or ore, and manage ash content and particle size. They operate and adjust machinery according to production plans to maintain processing efficiency and quality. They also handle sample collection and analysis in the laboratory, data recording, report preparation, safety inspections, maintenance, and repairs. Much of the work is done in teams, requiring a high level of safety awareness in work environments with dust and noise.
Future Outlook
Affected by fluctuations in energy supply and demand and the operation status of coal-fired power plants, but stably required in response to demand for imported coal. Automation is expected to advance due to environmental regulations and the introduction of labor-saving technologies.
