Penalty disposition
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.

Injury rate, 2002
This rate is reportable injury cases per 100 full-time-equivalent workers per year, computed as 200,000 times cases divided by MSHA operator-reported employee-hours. Cases are injuries MSHA graded degree 01 through 07; accident-only events that hurt no one are excluded, and so are contractor injuries, whose hours do not attach to a single mine. Rates begin in 2000, when quarterly employment reporting starts, and are withheld below 20,000 hours in a year.

days-away rate
0.000
fatality rate
Above average. The US coal mining average was 6.89 and the all-US-mining average was 5.05 cases per 100 workers.
Under 100,000 employee-hours were reported that year, so a single case moves the rate by two or more. Read the figure as approximate.
Year total case rate days-away fatal
2002 * 45.96 45.96 0.000
2001 * 39.00 35.45 0.000
2000 * 22.99 22.99 0.000
* Fewer than 100,000 employee-hours that year; the rate is less stable.

Health sampling
A sample is a point in time compliance measurement, not an individual exposure history. These figures describe MSHA sampling records and do not establish causation or personal dose.

Respirable coal dust
Respirable coal dust and silica figures cover coal facilities. Dust compliance is measured against the current 1.5 mg/m3 standard; samples predating the 2014 standard are included, so compliance rates are a coarse historical signal.

Noise
The share counts noise samples whose measured dose exceeded the 90 dBA permissible exposure limit. It describes the sampled workplace, not what reached the miner's ear: hearing conservation programs and the hearing protection worn during the shift are recorded separately and are not reflected here.

EE WAS REMOVING CRIB BLOCKS FROM LEFT RIB. HE WENT AROUND THE BACK END OF THE SCOOP TO GET THE CRIB BLOCKS ON THAT SIDE. AS HE DID, A PIECE OF ROCK FELL RROM THE RIB TO THE BOLTS. THE ROCK FEL L ON THE SIDE OF THE SCOOP & SLIDE DOWN CATCHING THE EE'S HEAD BETWEEN THE ROCK & THE MINE FLOOR.

Where Estil Stillwell stands on silica, penalties, and injury rate

MSHA's standard limits respirable silica to 50 micrograms per cubic metre, but MSHA publishes dust and quartz as separate files and never the silica figure itself. We derive it per sample, score it against the limit, and set the operator's injury rate against a benchmark built from the full MSHA operator record. With the 26-year penalty trail, contest posture, and fatality history. Delivered as a PDF with the underlying data as CSV.

The federal record itself stays free on this site. What costs money, and why.
