This <br />is based upon Information derived from D88~1 and D88~5. The slope angles are a functlon of the <br />exposed slope height. <br />Sector I and II Is controlled by Jointing within the strong Biotite Gneiss material. An inter-ramp <br />angle of 36° and 46° is recommended for these areas respectively. <br />b) West Wall <br />Sector W2 consists of Pink Gneiss which is rated as having a design SRMR of 5 - 1596. This is <br />based upon Information derived from D88~2 and D88-41. The slope angles are a functlon of the <br />exposed slope height. Sector W3 is comprised of Santa Fe materials having an SRMR of 5 - 159'°. <br />Due to the limited vertical extent an overall wall slope of 45° is recommended. <br />
