US mines with the most imminent-danger orders

Martinsburg has been placed under more Section 107(a) imminent-danger withdrawal orders than any other US mine in MSHA records, with 17 on file.

Individual US mines ranked by the number of Section 107(a) imminent-danger withdrawal orders MSHA has issued against them. Click a mine for its full incident and compliance record.

A Section 107(a) order removes miners from an area when an MSHA inspector finds an imminent danger; each is lifted once the condition is corrected, so this counts orders issued over time, not orders now in effect.
