Settlement calculations for the SGVLF foundation were primarily focused on the <br />regraded SGOSA slopes, since these slopes are anticipated to deform under the maximum <br />ore loads. The results of the analyses indicate that the anticipated settlements along the <br />SGOSA slopes will likely range from 2.4 to 29 inches under the applied ore loading. <br />These settlements are considered minor and not anticipated to damage the liner system as <br />they primarily occur as vertical deformations. The majority of the horizontal deformation <br />will be less than 12 inches. The shear strains on the slope will be less than four percent, <br />which is well within the acceptable strain limits for the LLDPE geomembrane liner <br />system. <br />For a complete discussion of the settlement analyses see Appendix 9, Volume V. <br />7.2.7.2 Stability Analysis <br />The geotechnical stability analysis of the SGVLF was conducted in a manner consistent <br />with previously approved analyses at the Cresson Project. As approved for the Cresson <br />Project, a peak ground acceleration of 0.14 g was used for the pseudo - static analysis <br />during operations and a peak ground acceleration of 0.08 g was used for the pseudo - static <br />analysis following reclamation. Upon reclamation, the outslopes will be flattened and the <br />FOS will increase due to the decreased slopes. Other input parameters were derived from <br />field examinations, laboratory tests, use of accepted numerical assumptions for certain <br />rock types, and the proposed dimensions of the SGVLF. Standard geotechnical modeling <br />was employed for the slope stability assessment. A complete discussion of the stability <br />analyses conducted for the SGVLF is contained in Appendix 9, Volume V. <br />FOS for the SGVLF were derived for static and pseudo- static conditions during <br />operations. The maximum side slope of 1.6H:1 V was calculated as part of an infinite <br />slope analysis that represents the steepest side slope that will occur at the SGVLF. The <br />majority of the slopes within the SGVLF will be buttressed by upsloping ground and will <br />have enhanced stability. The results indicate that the minimum static FOS was 1.3 and <br />1.5 or greater for operation and reclaimed static conditions, respectively and 1.0 and 1.1 <br />or greater for the pseudo- static conditions during operations and reclamation, <br />respectively. At reclamation, the ore side slopes will be regraded to a flatter side slope of <br />2.5H:1 V, which will increase the overall long -term stability of the SGVLF. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />7 -16 <br />
