Productivity: [(4 mph) x (5,280 ft) x (12 ft) . 43,560 ft2/acre]
x 0.80 availability = 4.65 acres/hour
Cost: ($144.23/hour) t (4.65 acres/hour) = $31.02/acre
Productivity Assumptions for Topsoil Replacement
Use Caterpillar 637D Scraper for topsoil replacement.
Average haul distances from soil stockpile will vary depending on the
particular area of the mine. Projected scraper productivities for
various haul distances at approximately 5% rolling resistance are shown
in the following table:
