To determine their effectiveness in different climate and soil conditions, a demonstration of dozer blades specifically designed for recontouring mine spoil was conducted at an east Texas surface coal mine. The specialized equipment included a 48-ft angle blade, a modified 24-ft 'U' blade, a 13-ft deep 'U' blade, and a 24-ft grading bar. Both the 48- and 24-ft 'U' blades were mounted in a two-tractor, single-operator configuration. To meet flotation problems common in this mining region, a 22-ft lightweight blade was developed and demonstrated for use on a 400-to-430-hp tractor. The demonstration involved 1,185 acres and showed a 50% reduction in reclamation costs and a 47% reduction in fuel requirements for this mine site over conventional equipment.
