The Mine Safety and Health Administration (MSHA) is a U.S. federal agency that sets and enforces safety and health standards for mining operations, conducts inspections, investigates accidents, and issues citations or fines. Its actions matter to investors because safety rules, enforcement actions, or accident findings can increase operating costs, interrupt production, create legal and cleanup liabilities, and damage a miner’s reputation—similar to how building inspections or traffic enforcement affect a company’s ability to operate smoothly.
