Jacob Dowdy, 24, was killed on August 16 at about 12.39am in a machinery accident at Thunder Basin Coal’s Black Thunder surface complex in Campbell County, Wyoming.

He was listed in the report as having two years and 50 weeks of mining experience, all of it at the Arch Coal operation.

“A P&H 2800 electric shovel was ascending an approximate 9% grade when the shovel lost propel capabilities and rolled backwards down the grade, crushing two Ford F350 flatbed utility pickup trucks,” the agency said.

“One pickup operator [Dowdy] received fatal crushing injuries and the second pickup operator was entrapped for approximately one-and-a-half hours.”

The injured miner was transported by ambulance to a nearby medical center for treatment. His updated condition was not available Monday afternoon.

According to federal data, the Black Thunder mine has 1574 workers, 1548 of which work at the mine itself. There were 277 miners on shift at the time of the incident.

MSHA classified Dowdy’s death as a machinery fatality.

Dowdy is the 13th miner to die in US coal in 2013 and the first in Wyoming.
