The mining slope was evaluated using Bishop's Method of Slices in the GALENA software. The <br /> results showed that the lowest factor of safety that produced a slope failure circle was 2.7. <br /> 2. Conclusion <br /> The mining slope analysis shows a failure at 1.0 factor of safety. This is below the minimum <br /> factor of safety for a permanent slope (1.2). However,the failure circle did not extend beyond <br /> the property line, and therefore there is no risk to neighboring structures.Additionally,the <br /> mining slope is not a permanent slope, as reclamation is required by the Colorado Mined Land <br /> Reclamation Board permit. This reclaimed slope has a factor of safety of 2.7. more than <br /> sufficient for permanent conditions. <br /> Ben Langenfeld,P.E. <br /> �••:: <br /> JO <br /> • •, ' a x11 <br /> o <br /> 0047151 <br /> It1i9'•11 14//rX0VQ <br /> 'i%►%SS'ONAIEN <br /> CO License#0047151 <br /> Orchard Grove Slope Stability 2 x ercg l.ew c i and Associates,1.1.1A` <br />
