• 1.0 Introduction <br />The purpose of this document is to present the stability of the landslide at the main facilities of <br />the West Elk Mine for eristing conditions and post-mining conditions. The stability is based upon <br />the characteristics of the landslide, analyses of corrective measures, and the monitoring <br />information. This document presents a brief characterization of the landslide, an overview of the <br />corrective measures implemented, the results of the analyses of the corrective measures, and a <br />summary of selected monitoring information. This information is used to establish the stability for <br />existing conditions and for post-reclamation conditions. <br />Mountain Coal Company is using the Observational Approach to landslide stabilization wherein <br />the implementation of corrective measures is based upon the monitoring information and the <br />performance of in-place corrective measures. Additional corrective measures are proposed and will <br />be implemented if the conditions warrant additional stabilization. These additional corrective <br />measures are also discussed in this document. Figure 1 is a plan of the landslide area which <br />shows the location of the existing and currently proposed corrective measures. <br />• <br />• <br />0626024\58991-LABM <br />
