• Final Volume of Material <br />This volume was determined by subtractingthe grid of the surface shown on Map 2.05.4-2Post-mining <br />Topography from the bottom of coal grid. <br />The Survcadd report for this volume is given below: <br />Volume Report 04/01/19 <br />Comparing GRiD file: C:/wfuels/botomelev.grd <br />and GRiD file: C:/wfuels/final2.grd <br />Grid corner locations: 1111982.96,599043.84 to 1119647.36,602981.92 <br />Grid resolution X: 200, Y: 200 Grid cell size X: 38.32, Y: 19.69 <br />Area in Cut : 7307.74 3q ft, 0.168 acres <br />Area in Fill: 15201599.21 sq ft, 348.981 acres <br />Total inclusion area: 15208906.95159 sq ft, 349.15 acres <br />Cut to Fill ratio: 0.00 <br />Average Cut Depth: 3.65 Average Fill Depth: 78.77 <br />Cut (C.Y.) /Area (acres): 2.83 <br />Fill (C.Y.) /Area (acres): 127025.06 <br />Cut volume is 26700.00 cubic ft, 988.89 cubic yards <br />Fill volume is 1197466281.70 cubic ft, or44.350.600 cv <br />The equation therefore becomes: <br />F~cisting OB Stockpiles Fill Last Cut = Final OB Volume <br />u <br />43,396,420 cv x 1.08 (% swell) + 432.000 cv - 2,800,000 cv = 44.350.600 cv <br />This formula is accurateto within 1 °~ and is therefore acceptable. Map 2.05.4-2 shows the post-mining <br />topography, which is nearly identical to the existing topography. Cross-section locations are also <br />shown on this map. <br />Typical cross sections through the mining areasare shown on Map 2.05.4-3. These cross sections <br />show existing, original, and postmining ground. In the New Horizon 2 area, the mined-out county road <br />(REVISED 9/99) <br />2.05.4(2)(c) - 6 <br />
