' D. Conclusions <br />' Increasing groundwater levels coupled with increasing displacement measured on the surface and at <br />depth within the colluvium indicates that landslide activity at some areas is continuing to occur at <br />the Main Mine Site and in Sylvester Gulch. A higher number of piezometers and stone columns <br />' than usual exhibited all-time high readings during the quarter, which is a reflection of the significant <br />snowpack and wet spring this year. <br />' Mirror data and inclinometer readings indicate that increased groundwater levels have produced <br />higher landslide velocities than measured over the past several years. Fortunately, the movement <br />' appears to have slowed or stopped after the first part of June according to the bi-weekly <br />inclinometer readings. <br />' Continued monitoring of the existing instruments located at the Main Mine Site and Sylvester <br />Gulch during the remainder of 2008 is recommended. The monitoring data are required to track <br />' displacement trends and give an indication regarding the stability of critical operational areas <br />throughout the Wesk Elk Mine. Also, as mentioned above, we recommend that the control point <br />(#50) in Sylvester Gulch be checked to determine whether or not it is moving. <br />Detailed designs associated with the stabilization of the power pole above the Material Storage <br />Bench have been submitted to West Elk Mine. The area west of the Main Landslide is still under <br />' review and analyses of this slope are being performed presently. <br />1 <br />i <br />1 <br />1 <br />1 <br />1 <br />Barr Engineering Company 2nd Quarter 2008 <br />' 06/26-031 Geotechnical Monitoring <br />
