Walnut Creek Mine
In November 2014, Kiewit Mining Group entered a 10-year contract to provide contract mining services for the Walnut Creek Mine.
The operation includes an 80-cubic-yard dragline, a 20-cubic-yard mass excavator, an 18-cubic-yard hydraulic backhoe and a fleet of 150-ton end-dump trucks to move more than 20 million cubic yards of material annually. The captive lignite operation can produce more than 2 million tons of lignite per year and incorporates a blending program that provides consistent quality lignite to fuel two 150-megawatt circulating-fluidized-bed power plants.
Quality control is maintained through a comprehensive testing program, and also includes an on-site staff of environmental specialists to ensure total compliance. The mine’s primary client generates, purchases, transmits, distributes and sells electricity to 250,000 residential, electrical and industrial customers in 85 municipalities in Texas and New Mexico.
