Pit: The average amount of spoil from the adjacent pit <br />in cubic yards. The spoil volune includes a 1.3 swell factor. <br />Excess/Deficit: Pit Void - Spoil from adjacent pit. <br />The last three columns ere a tabulation of the the excess or deficit in <br />spoil volume based on the Surface adjustment, pit void, aM spoil <br />from the adjacent pits. <br />The "worst case" for bond calculation purposes would be when pit 25 is <br />open but not beckfilled. [n this scenario the spoil fran 5 pits <br />back oust be graded into pit 25 in order to achieve approximate <br />original contour. <br />. SPOIL3.VK1 <br />12-5 July 1992 <br />
