Since the slope that is being considered is primarily uncrushed rock consisting of shales, <br />sandstones and siltstones, almost all of its resistive strength will be due to internal friction. <br />Cohesion is minimal in this soil. See the table from Huang - Stability Analysis of Earth Slopes <br />on the following page. The material will closely resemble a poorly graded gravel. <br />The material for the waste embanlanent will be underground development waste which may be <br />mined or unmined, and it may have many lazge pieces up to 12 inches in diameter. This material <br />will not be crushed prior to placement but will be compacted in small lifts in the embanlanent. <br />Typical intemal angles of friction of this material in the range of 34 to 42 degrees, and cohesion <br />of this material is effectively zero, due to the high percentage of material above sand size. <br />• <br />L J <br />
