This is reasonable because there is no water table within the soil mass being analyzed. <br />2.3 Stability Analyses <br />The cross section used in the previous analysis was taken through the area of the coal stack pad <br />expansion. This area is shown on Figure 2 and labeled as the approximate cut-slope and the <br />approximate fill-slope. The slope of the expansion pile was 2H:1 V. <br />I~ <br />L <br />The soil borings did not indicate a water table. In addition, the cross section used in the previous <br />analyses did not use a water table in the area of the R.O.M. pad expansion. <br />The factor of safety for the previous slope stability analysis of the lower slope was found to <br />equal approximately 1.49. The factor of safety of the upper slope was found to be 1.68. These <br />analyses were done using an earthquake acceleration equal to O.Og. <br />1 <br />P:UM~26V)30VtOMpileVenecdoc <br />
