This report discusses three earthmoving tools used in economically moving spoil piles during the mining process. The Pittsburgh and Midway Coal Mining Company (P and M) devised a method using two D9 tractors to move some 6000 to 8000 cu. yd. of spoil per hour at reasonable cost levels. P and M also has two additional pieces of equipment: a 24-ft wide V plow that makes the initial cuts at the peak of each crest, and a 24-ft wide grading bar that mounts onto the dozer blade of a D8 crawler tractor. Together, these three earthmoving tools provide for an economical method in moving spoil piles.
