Despite federal efforts to ensure safe working conditions for miners, they have one of the most difficult and dangerous jobs you can imagine. To recognize their efforts, Congress has declared December 6 National Miners Day. Why? Our entire economy depends on them. On this holiday, we should all take a moment to think about the many ways that miners play a role in our daily lives. Mined materials contribute to things like roads, houses, cars and computers. We wouldn’t be able to get much done without their hard work.
