Abstract
A demonstration of dozer blades was conducted at a northeast Arizona surface coal mine to determine their effectiveness in different climate and soil conditions. The specialized tools were a 48-ft angle blade on a side-by-side tractor, a 24-ft grading bar, a modified 24-ft "u" blade on a side-by-side tractor, and a 13-ft-deep "u" blade. Interest in the increased dirt-filling capacity of a previously built 22-ft blade resulted in the design of a new center- flow blade of good versatility able to maintain increased flow in otherwise difficult-to-move spoil. The demonstration involved 263 acres and showed a reduction of 50% in reclamation costs and 20% in fuel requirements over conventional equipment.
