ameO <br />Earth & Environmental <br />3) Topsoil Relocation <br />One CAT 375 loaded 40-ton articulating haul trucks with topsoil. Topsoil was transported to <br />the designated topsoil stockpile adjacent to the LOB Delivery Road. One CAT D-9 was <br />assisting the excavator. A CAT D-6 dozer was used to contour the upper and lower topsoil <br />stockpiles. <br />C) Overburden to Stockpile: <br />1) VLF <br />Oversize rock within in the Phase 5 VLF fill area was stockpiled using a CAT D-9 dozer for <br />future haul to the Joe Dandy Main Cresson Backfill. <br />2) VLF Subgrade Preparation <br />Subgrade preparation was performed between stations A23+50 (+/-) and A27+00 (+/-), <br />approximately 200 to 500 feet left of centerline. The site encompasses an area approximately <br />350 feet in length and approximately 350 feet in width. <br />Subgrade preparation was performed between stations A17+00 (+/-) and A20+00 (+/-), <br />approximately 50 to 300 feet left of centerline. The site encompasses an area of approximately <br />300 feet in length and approximately 100 feet in width. <br />All unsuitable material from the sites was loaded using one CAT 375 excavator and <br />transported using articulating 40-ton haul trucks to a designated site within the mine property. <br />The sites were scarified to a depth of 12" to 18" inches using a CAT D-10 dozer and moisture <br />conditioned using a CAT 773-water truck. Compaction was performed using a CAT 563 <br />vibratory smooth drum compactor passing over the subgrade surface with 4-passes. <br />3) VLF, PSSA Haul Road <br />No work performed during the week. <br />D) Cut to Fill <br />1) VLF <br />A John Deere 850D excavator and Komatsu 800 excavator excavated structural fill material <br />between stations J4+00 and J13+00 approximately 50 to 150 feet left of centerline and <br />transported using 777 haul trucks and 40-ton articulating haul trucks. Structural fill was placed <br />in the VLF between stations A17+00 (+/-) and A29+00 (+/-), approximately 50 to 400 feet left <br />of centerline and spread by a CAT D-9 dozer in 24" lifts. Structural Fill was placed using one <br />CAT D-8 dozer and a CAT D-10 dozer. Lift thickness was 18" to 24" (based on rock size). <br />Moisture conditioning of the fill was performed using a CAT 773-water truck. Each lift was <br />compacted with a smooth drum vibratory roller a minimum of 4-passes over the entire surface <br />(method compaction technique is applicable). <br />Rockbreakers drilled a shot pattern between stations A17+50 (+/-) to A20+00(+/-) using four <br />track mounted drill rigs. One shot was fired on Friday. Suitable material from the blast was <br />pushed toward the adjacent fill, using a CAT D-9 dozer assisted by a CAT 330 excavator, and <br />placed as structural fill. <br />Sheet 2 of 6 <br />VLF Weekly Report WE 05.30.09.D.doc
