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.

Somewhere between 12 and 1230, an EE asked EE to clean up the catwalk on the screen deck. EE was performing EE's normal work at a normal pace. While other EE was tramming the excavator, they noticed EE in distress and responded. EE went into cardiac arrest, 911 was called, CPR started, but EE did not recover.
