Reported miner-hours worked

The employment-hours figure is what sets this dataset apart. Reported miner-hours from 36,014 mines make it possible to compute a real safety rate (citations and injuries per million hours worked) for a mine or operator, rather than a raw count that just tracks size. Those rates appear on every mine and operator page.

Break the numbers down

How to read these numbers

Counts reflect what operators reported to MSHA and what MSHA published; they are not a danger score. A high violation count often just means a large operation with many inspections, and zero violations does not mean a mine is safe. Violations and proposed penalties begin in 1994, when MSHA's electronic enforcement record starts; accident records reach back to January 1983. Where a rate has no employment-hours denominator on file, the record says so rather than implying one.
