MSHA Mine Addresses of Record

Published by Mine Safety and Health Administration | Department of Labor | Metadata Last Checked: January 21, 2026 | Last Modified: 2025-12-15T14:23:58.430Z
Contains mine addresses for all mines in the database except for Abandoned mines prior to 1998 from MSHA's legacy system. The address is the one entered by the mine operator at the time a Legal ID form is completed for a requested mine identification number. It is updated by MSHA district offices as required. The mine id is the unique key for this data. (This includes Abandoned Mines and Abandoned and Sealed Mines, and does not represent the actual mine location.)
