What is NAICS 212115
NAICS code 212115 covers establishments primarily engaged in underground mining of bituminous and anthracite coal. This sector includes operations that develop underground mine sites, extract coal, and perform beneficiation processes such as cleaning, washing, screening, and sizing to prepare coal for commercial use. Businesses operating in this industry range from small specialized mining companies to large mining corporations with significant underground infrastructure. These companies employ advanced technologies and safety protocols to manage the complex and hazardous nature of underground coal mining. Government agencies contract these services to ensure a reliable domestic supply of coal for energy production and industrial uses, often supporting energy independence and economic development in mining regions.
