SLOPE STABILITY RESULTS <br /> The MLRB requires minimum safety factors of 1.50 for static condition analyses and <br /> 1.30 for pseudo-static (earthquake loading) condition analyses for embankments <br /> adjacent to critical structures. The calculated factors of safety are within the design <br /> criteria specified for this project and can be considered indicators of the mining slope <br /> performance under the various conditions. The slopes were analyzed using full and <br /> empty reservoir conditions. The results of the static condition and pseudo-static <br /> condition slope stability analyses are shown in Table 2 and Table 3. <br /> Table 2 - Static Condition Slope Stability Analysis Results <br /> Required <br /> Calculated Minimum <br /> Factor Factor of <br /> Description of Safety Safety <br /> Case 1 — Fence —to Slurry Wall Bench 2.30 1.50 <br /> Case 1 — Fence —to Bottom of Pit 2.33 1.50 <br /> Case 2— Fence —to Slurry Wall Bench 2.22 1.50 <br /> Case 2— Fence —to Bottom of Pit 2.38 1.50 <br /> Case 3— Fence —to Slurry Wall Bench 2.76 1.50 <br /> Case 3— Fence —to Bottom of Pit 2.40 1.50 <br /> Case 4— Fence & Lift Station —to Slurry Wall Bench 3.41 1.50 <br /> Case 4— Fence & Lift Station —to Bottom of Pit 2.42 1.50 <br /> Case 5— Sanitary Sewer, Water Line, Fence, Fiber Line, 3.04 1.50 <br /> Roadway, Bridge/Ditch, Structure, Power Poles and Lines, <br /> and Building —to Slurry Wall Bench <br /> Case 5— Sanitary Sewer, Water Line, Fence, Fiber Line, 2.42 1.50 <br /> Roadway, Bridge/Ditch, Structure, Power Poles and Lines, <br /> and Building —to Bottom of Pit <br /> Case 6—Water Line, Power Poles and Lines, Fence, 2.76 1.50 <br /> Telephone Line, and Oil/Gas Equipment—to Slurry Wall <br /> Bench <br /> Case 6—Water Line, Power Poles and Lines, Fence, 2.78 1.50 <br /> Telephone Line, and Oil/Gas Equipment—to Bottom of Pit <br /> J-2 Contracting Company—Sunset Industrial Pit <br /> Slope <br /> J&T Consulting, Inc.
