Pittsburg & Midway Coal Mining Co.'s McKinley mine near Gallup, N.M., is being expanded to increase annual production to 5 million by 1980. When completed the mine will produce from four seams of coal using four Bucyrus-Erie 55-cu-yd draglines. Previously, mining was limited to one seam worked by a 33-cu-yd shovel. Other features include a 75,000-ton stockpile and blending facility and a 3,000-tph unit-train loadout. Drilling, blending and pre-weighing as well as reclamation operations are discussed.
