High Availability: An Uptime Guarantee at Black Thunder Mine

To maintain the high level of production Arch Coal demands from its Black Thunder coal mine, the mine relies heavily on its fleet of Cat® trucks. To keep those machines running and to keep costs consistent, the site takes advantage of a Maintenance and Repair Contract (MARC) with Cat dealer Wyoming Machinery Company, which provides the support necessary to deliver the high mechanical availability and cost controls the MARC guarantees.
