Reduction of land recontouring costs. Volume II. bituminous coal field, northeast Arizona. Open file report Feb 79-Jun 82

Technical Report ·
OSTI ID:5632315
A demonstration of dozer blades, designed for recontouring area-mined spoil and shown effective at Kansas and east Texas surface mine sites, was conducted at a northeast Arizona surface coal mine to determine their effectiveness in different climate and soil conditions. The specialized tools were: 48-ft angle blade (on side-by-side tractor), 24-ft grading bar, modified 24-ft 'U' blade (on side-by-side tractor), and a 13-ft-deep 'U' blade. Interest in the increased dirt-handling 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 for this mine site over conventional equipment.
