were not applicable. For Waste Rock Disposal Area D the minimum <br />• FOS are 1.6 and 1.1. The single bench FOS for Area D are <br />identical to those for the South Waste Rock Disposal Area. <br />Under severe seismic loading the as-constructed angle <br />of repose slope faces may experience raveling and shallow slope <br />failure to assume a less steep configuration. Using a <br />pseudostatic coefficient of 0.15 g and a waste rock friction <br />angle of 35 degrees, simple infinite slope stability analyses <br />indicate that the end-dumped waste rock slopes may adjust under <br />seismic loadings from 1.5H:1V to approximately 2H:1V. As the <br />overall outside slope of the as-constructed waste rock disposal <br />facilities is 3H:1V with the inclusion of bench setbacks, the <br />anticipated slope adjustments under seismic loadings will <br />simply reduce the effective bench setbacks without impacting <br />the overall configuration of the facility. The waste rock dump <br />locations and setback benching configuration will accommodate <br />any minor slope adjustments while maintaining a net 3H:1V <br />• design slope and, therefore, will not affect the overall <br />configuration or stability of the facility during construction. <br />Upon reclamation, single bench safety factors are greater than <br />the required static and pseudostatic safety factors and no <br />slope adjustment is expected to occur. <br />D.4 Crushing Facilities <br />D.4.1 Description of the Crushino and Grinding Facilities <br />A crushing circuit will be constructed adjacent to the <br />mill facilities as shown on Figure C-1. The crushing plant <br />will consist of a feed hopper and a scalping feeder which will <br />feed run-of-mine ore to a grizzly and jaw crusher. Material <br />smaller than 8 inches will be screened from the ore going to <br />the jaw crusher. The jaw crusher will reduce the size of the <br />remaining ore to minus 8 inches. <br />~J <br />u-12 <br />
