Jones & Laughlin Mining Company, Ltd. operate the Adams mine at Kirkland Lake, Ontario, where they mine approximately 4,000,000 tons of extremely hard iron-formation and 3,500,000 tons of volcanic waste rock annually in order to produce 1,100,000 tons of iron pellets. This paper will discuss the maintenance of the four Model 1600 P & H shovels and the two 50-R drills used to obtain this production. The chief maintenance problems at the mine are due to the hard, abrasive ore and the cold winter weather
