MSHA sampling at Cobra Mine Prep Plant shows 97% of 79 respirable coal dust samples met the 1.5 mg/m3 standard.
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.

ⓘ
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.

Cobra Mine Prep Plant recorded 0.00 reportable injury cases per 100 full-time workers in 2008.
Injury rate, 2008
ⓘ
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.0.00

fatality rate
No reportable injury cases in any year shown. Employee-hours were reported in each of those years, so these are true zeros rather than missing data. Citations, listed in the compliance record above, are inspector-found violations and are counted separately from worker injuries.
Below average. The US coal mining average was 4.41 and the all-US-mining average was 3.61 cases per 100 workers.
In Pennsylvania, coal mining averaged 5.40 cases per 100 workers that year.
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.

| 2006 * | 0.00 | 0.00 | 0.000 |
* Fewer than 100,000 employee-hours that year; the rate is less stable.

Cobra Mine Prep Plant sits in Greene County, Pennsylvania, where the Census mining category is 5.2% of county employment.
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.Greene County, Pennsylvania · Population 35,265
