Geotechnical Evaluation of Mine-induced Seismicity on Monument Dam <br />Dorsey 8 Whitney, LLP <br />significantly exceeds the required yield acceleration of 0.04 g associated with a median peak <br />ground acceleration of 0.08 g at the dam site that could occur as a result of E Seam mine- <br />induced seismicity. <br />Results of the stability analysis are presented in Table 7.1. Computer plots of the stability <br />analysis results are provided in Appendix A. <br />TABLE 7.1 <br />RESULTS OF PREVENTIVE MEASURES STABILITY ANALYSIS <br />~1 <br />LJ <br />l J <br /> Recommended Yield <br />Case Phreatic Surface Static FOS Minimum FOS Acceleration <br /> lg) <br />Earthfill Dam High level within dam 1.6 1.5 --- <br />Earthfill Dam Yield High level within dam --- -- 0.13 <br />Accel. <br />Landslide Threshold water levels 1.6 1.5 --- <br />Landslide Yield Threshold water levels --- -- 0.11 <br />Accel. <br />GEI <br />26 <br />060350 O60I-I6 Mamm~rnc Dam GmtNmicd Evil <br />March 2006 <br />
