Newmont-Cripple Creek&Victor Go►d Mine _■ <br /> Technical Specification No.02200.DOCX <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> no excessive gaps are left between successively dumped loads of materials. The fill <br /> shall be leveled prior to compaction by means of a dozer or grader, or other <br /> suitable approved equipment, to obtain a surface free from depressions. <br /> 7. Except in areas approved by MANAGER and CERTIFYING ENGINEER where space is <br /> limited or otherwise specified, CONTRACTOR shall place fill by routing the hauling <br /> and spreading units approximately parallel to the axis of the fill. As far as practical, <br /> hauling units shall be so routed that they do not follow in the same paths, but split <br /> their tracks evenly across the surface of the fill to enhance compaction. <br /> 8. CONTRACTOR shall apply water required for moisture conditioning on the fill or in <br /> the borrow areas. <br /> CONTRACTOR shall maintain fill materials within the moisture content range <br /> required to permit proper compaction to the specified density with the equipment <br /> being used. The moisture content of the fill materials, prior to and during <br /> compaction, shall be uniform throughout each layer of the material. <br /> Prior to mixing of wet and dry material on the fill to obtain the proper moisture <br /> content, approval shall be obtained from CERTIFYING ENGINEER. Mixed material <br /> shall have a uniform distribution of the moisture content prior to placement on the <br /> subsequent lift. <br /> When materials spread on the fill are too dry for proper compaction, CONTRACTOR <br /> shall spray water on each layer of the fill and shall work the moisture into the fill by <br /> harrowing or other approved means, until a uniform distribution of moisture is <br /> obtained. Material that is too wet for proper compaction, as determined by <br /> CERTIFYING ENGINEER, shall be removed from the fill and/or spread out and <br /> permitted to dry, assisted by disking and harrowing or mixing in dry material when <br /> permitted by CERTIFYING ENGINEER, if necessary, until the moisture content is <br /> reduced to an amount suitable for obtaining the specified degree of compaction, at <br /> no cost to CC&V. <br /> 9. After each layer of fill material has been placed, spread, and moisture-conditioned, <br /> the layer shall be compacted by passing compaction equipment over the entire <br /> surface of the layer a sufficient number of times to obtain the required density, as <br /> specified herein. Compaction shall be accomplished with equipment and by <br /> methods approved by CERTIFYING ENGINEER. If such equipment or methods are <br /> found unsatisfactory for the intended use, CONTRACTOR shall replace the <br /> unsatisfactory equipment with other types or adjust methods until proper <br /> compaction is achieved. Prior to placement of a subsequent lift, the previous lift <br /> shall be thoroughly scarified to a nominal depth of 2-inches to provide good <br /> bonding between lifts. Scarification shall be accomplished by disking, raking with a <br /> grader, or an alternative method approved by CERTIFYING ENGINEER. <br /> Page 10 <br />
