February, 2005 <br />Table 1 -SOILS DATA <br />Stratigraphic Layer Density Cohesion (psf) Phi (~) <br /> (pcf) <br />Silt and Clay -ML 90 4 34 <br />(moist) <br />Gravel (moist) GW- 130 0 35' <br />unsat. <br />Gravel (saturated). 137 0 35 <br />G W-sat. <br />Weathered Claystone 142 0 14 <br />(saturated) <br />Intact Claystone (dry) 150 500 25 <br />1.3 MODEL OUTPUT <br />The model output information including the failure circle for FS = 1.0 is provided in the <br />Appendix for each mining phase and cell. Table 2 summarizes the recommended <br />setback for each mining phase and cell based on relatively conservative soil <br />characteristic parameters. It should be noted that minimum factors of safety were <br />determined for each slope analyzed and in all cases, the proposed slope with assumed <br />stratigraphy and soil characteristic parameters returned a value for FS of less than 1.0, <br />indicating that the proposed slope would fail under the existing conditions. <br />Fort Lupton Pit Stope Stability Study, Page 2 of 5 <br />
