At approximately 12:10 p.m. on Wednesday, March 12, 2008, John G. Workman, a 47-year old self employed contract mechanic with 20 years of total mining experience, and one month of experience at this mine, was fatally injured as he was removing a belly pan from a Caterpillar D10N bulldozer, to access engine components. The belly pan was supported by a chain tensioned by a truck-mounted crane. When the victim removed the belly pan mounting bolts, the chain slipped, causing the pan to trap the victim, resulting in fatal injuries.
The accident occurred because the belly pan was not properly supported before removal of the mounting bolts. Additionally, the front hinge of the belly pan was broken, which allowed the belly pan to rotate as it fell, causing the chain support to slip.
