2.2 RECOMMENDATIONS <br /> We belive that the mine plan is adequate to ensure a stable long-term pit wall. <br /> Minor modifications to the pit geometry could enhance local stability and improve the <br /> performance of the catchment benches. The following specific recommendations are <br /> proposed. <br /> • Geologic mapping of structural features should continue in order to define any <br /> intermediate size wedge or plane instabilities before daylighting. An active <br /> transfer of the geologic data and interpretation of the wedge geometry to the <br /> pit engineers should be implemented on a routine basis. <br /> • Aggressive scaling of the bench faces should continue to assure that loose <br /> materials are removed. <br /> • Bench face angles should be increased to 90' and bench widths increased to <br /> around 18 feet. <br /> • The talus slope at the top of the east wall should be cut back to reduce the face <br /> angle to below 45°. <br /> • Procedures for installing rockbolt support for local intermediate size blocks <br /> should be developed. <br /> • Controlled blasting procedures should be continued and improved. <br /> 3 <br />
