GEOTECHNICAL STABILITY EXHIBIT(CONT) Page 3 <br /> face will be mined and cut/filled we included a safety factor for <br /> the cut face and for the final reclamation slope . <br /> The material in the mine wall will be in-place sand and <br /> gravel and assumed to be cohesionless and having an assumed <br /> natural friction angle ((D) of 35' (z1 . 43 : 1) . <br /> Using the measured angles from the cross sections, the <br /> safety factors for each slope were calculated usingg the 35o ((D) <br /> as the base angle . The safety factors are shown in the following <br /> table using the formula FS = Tan(D -Tang, where 6 is the slope <br /> angle from the toe of the created slope to the closest structure . <br /> The Safety Factors have been calculated for the �4: 1 and the 3 : 1 <br /> slopes at each cross section location and are shown on the <br /> attached Table B. <br />
