Show INDUSTRIAL COMMISSION TELLS CAUSE OF FATAL MINE MISHAP Leon Irvin Hansen, 35, Union, was killed in a Lark mine when a muck bucket was pulled up too far on a hoist, causing the cable to break and-Uhe bucket to fall, the State Industrial Commission Com-mission reported Friday. Otto A. Wiesley, commission chairman, released the report of the June 26 accident. The report was prepared toy V. GPett, safety safe-ty inspector. The report gave these circumstances circum-stances of the fatal accident: Mr. Hansen was working near the bottom of a 300-tfoot shaft. A loaded muck bucket (which witnesses wit-nesses at the scene said weighed about 1,500 pounds) had been sent up the shaft. The bucket was connected to a five-eighths inch cable, fed through a pipe-like guard before it rolled over a pulley called a "sheave." The bucket struck the pipe, the cable broke and the heavy bucket fell about 300 feet. "The falling bucket hit the mucking muck-ing machine and knocked out sunporting timbers. It also struck Hansen and knocked him down the shaft," the report said. Mr. Wiesley said determination of the cause of the accident was based on the finding that exactly 192 inches of cable were attached to the bucket. That is the exact distance from the sheave wheel to the bottom of the guard, he said indicating that the impact of the bucket on the guard caused caus-ed the break. Mr. Hansen was employed by Boyles Bros. Drilling Co., contractor con-tractor to U. S. Smelting Refining Refin-ing and Mining Co. |
