Geotechnical Stability Exhibit <br /> Engineering Evaluation of Highwall Design for the South Quarry of the Morrison Quarry <br /> 5.2.3 Slope Stability Analyses <br /> Slope stability of the existing and proposed bench configurations at the South Quarry were <br /> primarily performed in the RocScience SLIDE2 program, utilizing sections cut from the 3-D <br /> geologic model. Simplistic bench and material configurations were also checked in <br /> FLAC/Slope. Material properties utilized in design were consistent between the SLIDE2 and <br /> FLAC/Slope analyses. <br /> 5.2.3.1 SLIDE2 <br /> Results of the existing and proposed factors of safety generated by the SLIDE2 models are <br /> provided in Table 11. <br /> May 2023 1 26 <br />
