Approximately 480 cubic yards (240 cubic yards per <br />layer) of select structural fill was used between geogrid layers in 6 -inch compacted lifts. <br />Approximately 481 cubic yards of select structural fill was used above the final layer of geogrid in <br />a 12 -inch compacted lift. Prior to compaction, the select structural fill material was moisture <br />conditioned using a CAT 773 water truck. Compaction of the select structural fill was then <br />performed using a 104on smooth drum compactor using the static method. <br />The crown pillar at Underground Working #4073 was removed using a CAT 330 excavator and <br />observation was performed by an AMEC field representative. The working was completely <br />removed during excavation and competent rock was encountered. A CAT 330 excavator was <br />MEW Weekly Report WE 07.14.2012 <br />
