In-Pit Conveying at the Wyodak Mine—Gillette, Wyoming

摘要

The Wyodak Mine is located in the northern Powder River Basin of Wyoming and is thought to be the oldest continuously operating coal mine in the United States, having recorded yearly production since 1923. The mine has expanded over its 80-plus-year history from an underground room and pillar operation to a modern surface strip mine. Currently, the mine feeds four on-site power plants using conveyors, has a fully automated truck load-out, and ships coal by rail to nearby Wyoming power plants. Annual production of 4.8 MTPY is accomplished on a single-shift basis with 53 full-time production, maintenance and administrative personnel.
