Safety Analysis of United States Shaft-sinking Operations.
NTIS: PB 282 289 Available for Reference At Bureau Libraries :289 pages
The safety analysis of shaft-sinking operations included a review of accident reports from coal and metal-nonmetallic mine shaft-sinking projects in the United States, a review of foreign and domestic shaft laws, and discussions with shaft contractors and federal mine inspectors. Accident data were studied to identify the most common and the most severe types of shaft accidents and to determine their immediate and contributing causes. Additional factors such as worker training and experience, equipment and sinking procedures, regulations, and enforcement practices were also investigated to determine their impact on shaft safety. The results of the study are summarized in recommendations for improved training of shaft miners and clarification of federal shaft-sinking regulations. A guide to assist mine inspectors in examining shaft-sinking projects is also included.
