Loading of bench and outer rows should be the same as is normally used at Cresson, <br />until experience is gained in this material. <br />5. Blasting Order. The delay pattern for the blasting system should result in blasting to the open <br />face, with the trim row being the last to be detonated as the blast moves through the azea (to <br />minimize wall damage). <br />6. Vertical Face. The proposed strategy will occasionally result in some overhang on the wall. This <br />is acceptable, as the design does not require any unprotected personnel to operate under any <br />overhang. <br />A schematic blasting pattern is presented in Plate 4 for the 60° slope case. <br />Report 1385L.200309017 20 <br />
