Query MSHA mine inspection and violation data via the DOL Enforcement Data API

Steps
Register for a free API key at the DOL data portal if you don't already have a DOL developer token.
Query Basic Mine Information / Full Mine Information Mines for identifying data on every Coal and Metal/Non-Metal mine under MSHA jurisdiction since 1/1/1970.
Query Mine Inspections for every MSHA inspection (mine, event number, inspection type, start/end dates) since 1/1/1978.
Query Mine Violation for violations issued as a result of those inspections and Mine Accident Injuries for accident/injury/illness reports since 1983.
Send your token in the `X-API-KEY` header and page through results with offset-based pagination.
Known gotchas
The documented Mine Violation dataset's stated coverage window (1978–2000) is older than the other MSHA tables — confirm current coverage before relying on it for recent violations, and cross-check against Mine Inspections for newer activity.
MSHA data is split across separate DOL datasets (mines, inspections, violations, accidents, employment/production) that must be joined client-side on mine ID/event number — there's no single "mine safety" endpoint that returns everything at once.
The same DOL-wide API key and offset-pagination mechanics apply as for the OSHA Enforcement dataset, so one registered token can query both.
