Rock Dusting
Rock dusting is a crucial safety practice in coal mines where workers spread powdered limestone (rock dust) throughout mine tunnels. This simple but important process helps prevent coal dust explosions by mixing non-explosive limestone dust with potentially explosive coal dust. Think of it like adding a fire-suppressing material throughout the mine. It's a basic but essential safety measure that all underground coal mines must follow by law. When you see this term in resumes, it usually indicates experience with mine safety procedures and compliance with federal mining regulations.
