VI - SLOPE STABILITY RESULTS <br />The SEO requires minimum factor of safety of 1.25 for static condition analyses and 1.0 for <br />pseudo-static (earthquake loading) condition analyses for Class I (high hazard) embankment <br />dams. This design criteria was used to establish the desired minimum factors of safety for this <br />project and should be considered as highly conservative for evaluating alluvial mining high <br />walls. The calculated factors of safety are within the design criteria specified for this project and <br />can be considered indicators of the high wall performance under the various conditions. The <br />results of the static condition and pseudo-static condition slope stability analyses are presented <br />in Table 2 and Table 3. <br />Table 2 - Static Condition Slope Stability Analysis Results <br /> <br /> <br />Description <br />Calculated Factor <br />Of Safety Required <br />Minimum Factor <br />Of Safety <br />Case 1 1.42 1.25 <br />Case 2 1.84 1.25 <br />Case 3 1.62 1.25 <br />Case 4 1.42 1.25 <br />Case 5 1.49 1.25 <br />Case 6 1.46 1.25 <br />Case 7 1.26 1.25 <br />Table 3 - Pseudo-Static Condition Slope Stability Analysis Results <br /> <br /> <br />Description <br />Calculated Factor <br />Of Safety Required <br />Minimum Factor <br />Of Safety <br />Case 1 1.15 1.00 <br />Case 2 1.39 1.00 <br />Case 3 1.26 1.00 <br />Case 4 1.11 1.00 <br />Case 5 1.18 1.00 <br />Case 6 <br />? <br />_ 1.17 1.00 <br />Case 7 <br />? 1.06 1.00 <br />Journey Ventures, LLC - Kersey Gravel Pit <br />Slope Stability Analysis <br />Page 4
