-2- <br /> Total Cost Facilities Removal = " $ 73,800.00 <br /> Backfilling and Grading <br /> 1 . Bin Backfilling <br /> Material for backfilling the bins will be available from the base material of <br /> the Mine No. 2 coal stockpile and the alternative coal stockpile. It is <br /> assumed that two feet of material will have to be removed during reclamation <br /> to dispose of all coal . <br /> The Mine No. 2 coal stockpile has a base area of approximately 200 feet by 700 <br /> feet. The alternative coal stockpile area hr a base of approximately 450 x <br /> 175 feet. This makes a total available volume of backfill material of 16,200 <br /> cubic yards (cy) . <br /> A total volume of 36,644 cy will be required to backfill each bin. The <br /> additional material will be obtained from the coal refuse pile. <br /> The average haul distance from the Mine No. 2 coal stockpile is 4,200 feet one <br /> way; the average distance from the alternative coal stockpile is 1 ,250 feet <br /> one-way; and the distance from the Sutey refuse pile is 5,850 feet. <br /> 637D scrapers will be used to haul the backfill material .
