A 4.5 m high stope has an angle B-45° A trial toe circle has been used, for which a horizontal distance from the center O to the toe (X-4.5 m) and vertical distance from the center O to the toe (Y) 6.25 m). The soil mass is assumed to be divided into 4 slices all having identical width of b-3 m, whose average height (h) and angle (u) are tabulated on Table 2. Assuming that there is an embankment placed 1.0 m from the cut edge with distributed load of -10 kN/m². Given that: -6.75kPa. -20°. p-1.96 Mgm' (density of saturated soil mass), Yary 17 KN m Table 2.
