Fisher Sand & Gravel has procured a 2.5 year contract to supply the North Antelope Rochelle Mine (NARM) with nearly 5 million tons of scoria. NARM is located 65 miles south of Gillette, WY and is the world’s largest open face coal mine, producing over 100 million tons of coal a year. The mine has some 1.7 billion tons of provable and probable reserves. They move a million tons of overburden a day: moving up to 400’ of overburden to get to a coal seam of around 80’. The mine is owned and operated by Peabody Energy. Approximately 1,500 people work on site during the day.
The scoria we will be suppling is located within the mine site at two different locations. The scoria will mainly be used on the haul roads when they are wet. The overburden is a bentonite material, and therefore gets quite slick with moisture. It is not uncommon for the mine to haul up to 40,000 tons of scoria overnight.
