ⓘ
This rate is recorded citations divided by MSHA inspection hours, per 100 hours. It reflects inspection effort, not mine size or production.ⓘ
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.ⓘ
Shares are computed over citations that carry the MSHA gravity and negligence coding; a small share of records are uncoded.ⓘ
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.| Year | total case rate | days-away | fatal |

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.

The excessive concentration value (ECV) is MSHA's own per-sample enforcement threshold, which builds in measurement uncertainty; a sample over its ECV can trigger a citation. The count covers only samples MSHA assigned an ECV.- CONTINUOUS MINER OPERATOR9,135

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.

Fatalities under this operator
4 recordedTHE OFF-STANDARD CAR OPERATOR IN THE 7 LEFT SECTION WAS FOUND FATALLY INJURED, PINNED BETWEEN THE CAR CANOPY AND THE RIB. THE CAR WAS STOPPED AT THE FEEDER BREAKER FOR THE SECTION. AN INVESTIG ATION IS UNDERWAY TO DETERMINE FURTHER INFORMATION.
INDIVIDUAL WAS FOUND DEAD IN SUMP.
VICTIM WAS DRIVING A WAGNER DIESEL POWERED SCOOP OUT OF THE MINE WHEN FOR SOME UNKNOWN REASON, THE SCOOP TRAVELED BACK DOWN THE SLOPE AND THE CANOPY STRUCK AN "I" BEAM ON A OVERCAST WHICH CAUS ED THE CANOPY TO DEFORM, STRIKING THE VICTIM, INFLICTING FATAL INJUIES.
Where Canyon Fuel Company LLC 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.
