Results of the stability analysis for the operational condition <br />• are shown in Table 1 and typical failure surfaces are presented <br />on Figure 3. Summary of the minimum factors of safety, relative <br />stability of the conditions analyzed and critical modes of <br />failure are presented in Tables 2 and 3. These minimum factors <br />of safety conditions are also presented graphically on Figure 4. <br />As shown on Tables 1, 2 and 3, the stability conditions for the <br />bench fill are relatively sensitive to changes in the piezometric <br />conditions, while the highwall section is relatively insensitive. <br />The overall results of the analysis for the operational <br />conditions may be described as follows. Under most conditions <br />analyzed, the bench fill slopes below the portal were found to <br />have theoretical factors of safety less than 1.0. The overall <br />highwall slope above the portal facilities were found to be <br />• stable with factors of safety greater than 1.5 and presents no <br />potential for instability as a result of circular failure through <br />intact rock. <br />RECLAMATION CONDITIONS <br />The proposed reclamation conditions were evaluated utilizing <br />~ methods similar to that performed for the operational conditions. <br />The exception was the determination of the sensitivity analysis <br />for optimization of cut and fill sections for the reclaimed <br />slope. The results for the stability analysis on the reclaimed <br />slopes are presented in Table 1 and summarized in Tables 2 and 3 <br />and shown graphically on Figure 3 and 4. <br />The overall results for the analysis on the reclaimed slope can <br />I• be described as follows. As with the operational conditions, the <br />6 <br />
