An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 ft high. The trucks will be loaded from an ore chute with a loading rate of 300 tons/hr. The mine employs two 10-hr working shifts. Overall job conditions are assessed as severe. The limestone has bank density of 0.0795 tons/ft3 and swell factor of 0.59. Select the type and size of the truck needed, and calculate the size of the truck fleet needed. Make and justify all assumptions needed (clearances, turning radius and other factors).
