6. ANALYSIS OF POSTMINING TOPOGRAPHY PROJECTIONS <br />• Requirement <br />The analysis of the postmining topography will serve to verify the accuracy of the postmining <br />topography projections. Monitoring for this purpose will remain the same as in the past, utilizing <br />accepted aerophotogrammetric methods. <br />Exhibit 9 - 1999 Annual Report Man. shows the mine configuration and reclamation progress as of <br />the September 29, 1999 aerial flight. <br />Three cross section (1-1', 2-2' and 3-3') are submitted which compaze the actual versus the predicted <br />postmining topography, as well as the premise topography and original box cut/F or X seam <br />contour line. These cross sections are submitted as F. hibi 10. These cross sections indicate that <br />the difference between the actual versus predicted postmining topography is very slight and well <br />within acceptable mining practice. <br />• <br />u <br />l3 <br />
