Local economic context
ⓘ County figures come from the US Census Bureau's American Community Survey, 5-year pooled estimates, so the 2023 vintage covers 2019 through 2023. The Census category is 'mining, quarrying, and oil and gas extraction', which is broader than MSHA jurisdiction and includes oil and gas workers no mine employs. These figures describe the surrounding county, not this mine, and are not a factor in any specific incident.

How to read these numbers

The register is MSHA's Mine Data Retrieval System: every operation ever assigned a mine ID, including ones abandoned decades ago, so the count is a history of mining in the county, not a count of working mines. A mine's county is the one its operator reported to MSHA. Fatality and accident counts start with MSHA's reportable-accident records (1983 onward); citation counts are inspector-issued violations on record. We are an independent research tool, not MSHA.
