HANDLING OF MATERIALS at River View Coal LLC
The injured and another employee had changed out a canopy post on the right side roof bolter machine. Both had loaded the old post on a 3-wheeler to take it to a diesel ride that would be used to take the post outside. While they were loading the post from the 3-wheeler to the diesel ride, he felt and heard a tearing sensation in his right upper arm (bicep).
