This process is also discussed in the Backfillinq and Grading Plan <br />found in Tab 18. <br />The first step is the determination of volumes. Cross sections were developed in the rail <br />spur area with the aid of a computer program from SoftD esk (see Exhibit 18-2). Postmine <br />slopes were then superimposed on the diagrams. For the sake of continuity, it was <br />estimated that all material would be graded toward the railroad cut at slopes between <br />Sh:ly and lOh:ly when sufficient adjacent land was available. A digitizer was used to <br />balance the cut and fill volumes of material needed to create the above-described <br />topography. This produced a final topography that could not only be revegetated, but <br />would also allow drainage to flow through the reclaimed area without impounding water. <br />A Caterpillar computer program called Earthmovinq Fundementala (EMF) was used to determine <br />dozer production. This program utilizes information given in the Caterpillar Handbook. <br />All tables and charts have been computerized to simulate production for track type <br />equipment. See various aorkaheata (aee attachment 23-1) fox production and costs. <br />Due to the fact that the cuts will not be completely filled in, it is not anticipated that <br />wheel type earthmovers will be needed to bac kfill the cut areas. Sufficient material <br />exists adjacent to the cut ar eas for backfill purposes. <br />Topsoil Replacement. Topsoil replacement volumes were based on the volume of material in <br />stockpiles as determined by the soil survey. A Caterpillar computer program called Fleet <br />Production Coat Analyaia (FPC) was used to estimate scraper production. FPC printouts in <br />Attachment 23-2 list the production time associated with topsoil replacement. <br />The topsoil replacement cost estimate was completed with the aid of FPC. All FPC <br />parameters are listed for each project area." <br /> 2 Revised O6/00 <br />
