GENERAL <br />This report presents the results of our geotechnical <br />laboratory study and slope stability analysis for the proposed <br />reclamation of the portal area at the East Side Coal Company <br />Mine. The site is Located about five (5) miles north of <br />Silt, Colorado near the Harvey Gap Reservoir. The purpose <br />of our study was to assess the stability of tl~e proposed <br />slope at the completion of the reclamation project. uur <br />geotechnical slope stability analysis w,i :. ba:;e r1 on lal,uratory <br />remolded triaxial tests performed on soil samples received in <br />our laboratory and on a cross section of the proposed <br />reclamation area showing both the existing slope configuration <br />and the proposed final slope configuration provided by t1r. <br />Steve Self. It is our understandiny baE.ed on conversations <br />• with Mr. Steve Self that the material received in our <br />laboratory was a sample of thi: foundation :or L; at Lh1• site. <br />Our analysis also included soil .strength values for the <br />proposed fill material determined in our earlier study an.l <br />report for the proposed spoil pile. T}le results of our <br />laboratory work are presented in Appendix A. <br />DISCUSSION AND RECOMMENDATION:• <br />Subdrains <br />It is our opinion that water will tend Co collect at <br />the fill/natural contact.
