Which regulatory body oversees the health and safety of miners?

The Mine Safety and Health Administration (MSHA) is specifically responsible for overseeing the health and safety of miners in the United States. This federal agency was established under the Federal Mine Safety and Health Act of 1977, which aimed to improve safety conditions in mines and reduce the incidence of mining accidents and fatalities.

MSHA's role includes enforcing safety and health regulations, conducting inspections, and providing educational resources to mine operators and workers. The agency's directives are focused solely on mining operations, which distinguishes it from other agencies. While the Environmental Protection Agency (EPA) deals with environmental regulations, and the Occupational Safety and Health Administration (OSHA) addresses workplace safety across various industries, MSHA is dedicated to mining safety. The Department of Labor (DOL) oversees various labor-related matters but does not specifically target the unique conditions and risks associated with mining. Therefore, MSHA is the correct regulatory body for ensuring miner's health and safety.
