METAL/NONMETAL MINE FATALITY - On August 18, 2008, a 28 year-old contractor mechanic/welder with 8 years experience was fatally injured on the surface at an underground stone mine. A crane was being used to lower into place a 7,000 pound counterweight for a scaling machine. The victim was checking alignment of the bolt holes for the counterweight when one of connectors on the rigging broke, causing the counterweight to swing and strike him. The second connector then broke and the counterweight fell on top of the victim.
