Today’s sad news comes from Indiana, where a coal miner was killed earlier this week at the Gibson Mine owned by Alliance Resource Partners. Here’s the preliminary report from the U.S. Mine Safety and Health Administration:

On Tuesday, March 25, 2014, at approximately 1:45 a.m. (CDT), a mechanic trainee was fatally injured while working on an Auxier Welding Inc. belt feeder located on the No. 4 working section. The victim was in the process of cutting through the inner left-side side plate, and when the cut was completed, the cat frame pivoted upward, pinning the victim between the cat track and frame of the feeder. The side plates connect the hopper jack assembles to the cat frame.

That makes three U.S. coal miners killed on the job so far in 2014.
