The lowest factor of safety for permanent slopes is 1.38 at Final Reclamation. This is below the <br /> CDRMS permanent slope minimum (1.5) for critical structures but above the non-critical <br /> structure minimum (1.3). However, the FoS = 1.5 failure circle is nearly identical in size and <br /> location to the 1.39 failure circle. The FOS = 1.5 failure circle is well within the bounds of the <br /> operation and does not risk any offsite structure or the overall slope stability of the reclaimed pit. <br /> Seismic conditions were also analyzed. The worst case FOS for seismic is 1.22. Similar to the <br /> static condition, this FOS is below the CDRMS critical structure minimum (1.3) but above the <br /> non-critical structure minimum (1.15). Failure circles for the seismic conditions were the same <br /> as the static conditions. <br /> GALENA data tables and analysis result figures are attached as Appendix GS-1. <br /> Hard Rock Benches <br /> (overall slope of 211:1V) <br /> Final Reclamation <br /> I with backfill <br /> (slope 2H:1V) <br /> 1 <br /> Figure GS-1.
