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.

Trying to walk the Hitachi dump truck off the hill after losing the track. Truck was going to go over the hill, so to avoid being crushed, I jumped and slid down a 50" rock face, injuring my ankle, knee, shoulder, and elbow on my right side, and cutting my right hand.
