The operators with the most open mines are Vulcan Construction Materials, LLC; Martin Marietta Materials Southwest, LLC; Thompson Materials. Data from MSHA, November 6, 2026.

SpecStream is the live web data engine for teams and agents. It reads the mine, citation, inspection and accident files that MSHA publishes, and this page is that reading. Ask for the mines of a commodity, state or operator with the operator's headquarters, website and size added from the web, and new mines, new citations and new accident reports arrive in your sheet, CRM, Slack or agent as MSHA posts them.

Updated November 6, 2026. Read from US Department of Labor, Mine Safety and Health Administration (MSHA), Open Government Data Sets. US government work, public domain. Counts come from the MSHA files published on November 6, 2026. An open mine is one MSHA lists as Active, Intermittent, New Mine, Temporarily Idled or NonProducing; 13,673 were open that day. Citations, penalties, inspections and accident reports run from January 1, 2022. A citation is an inspector's allegation and an operator can contest it; the penalty is the amount MSHA first proposed, before any contest or settlement. An operator is the legal entity MSHA assesses, and a parent company is its controller. Mines run by sole proprietors or by individuals are counted in every total and are not named. This page uses MSHA data and is not endorsed or certified by MSHA. Free to reuse with credit to SpecStream under CC BY 4.0. Spot a wrong value? Write to [email protected] with the link to this page.
