Privacy

What this site publishes

Federal public-domain data. MSHA's file says the controller's name may be a person's name: this site never publishes it. A mine run by a sole proprietor, or whose operator is named after a person, is found by mine ID only, with no operator shown.

What your browser sends

No analytics, no advertising, no cookies. Searches run in your browser against static files. A click on a referral link is counted (site, link and page — no visitor identifier). The host (Cloudflare Pages) keeps ordinary server logs.

How we are paid

• Dated reports and Pro access.
• Referrals: pages and records can carry one of two links — to a micro1 video-data program for businesses, or to Registres, an independent data gateway. This site may be paid a fee if a business that applies through one of these links is accepted. No one pays to appear here.

Corrections and removal

The data is a public record. If something is wrong, or you want an entry removed from this site, write to us: we cannot change the official file, but this site is not the government.
