Spring Creek is an open pit coal mine located approximately 37 miles north of Sheridan, Wyoming, in Big Horn County, Montana. The Spring Creek Mine operates 24 hours a day, 7 days per week, employing a work force of more than 200 people. Rio Tinto Energy upgraded the equipment fleet and other infrastructure to meet strong coal sales demands.
The Spring Creek Mine purchased several new large dump trucks which did not fit inside the existing facilities for maintenance or washing. In order to facilitate the larger dump trucks, Big-D Construction crews increased the existing truck shop area by adding a 22,000 square-foot, tandem-bay truck shop addition and a new 11,000 square-foot truck wash building. The Spring Creek Mine truck shop addition also included an entirely new lube maintenance facility. Rio Tinto needed to minimize disruptions to mine operations during construction, so Big-D took a flexible approach and coordinated with the mine’s management. The mine was able to remain in full operation for the duration of construction.
