When that is opened the sail is once again stripped from the area where <br />• er.pansian will occur, e;:cept for a narrow strip of sail right on the <br />edge of the pit which is usually iost and incorportated iota product. <br />The road is then reduced in grade and the e;:traction proceeds. <br />Eventually the pit simply expands into the entire permitted mining <br />area. As the edges of the mining area are approached adjustments and <br />plans must 6e incorporated into the mining which will allow far the <br />production of the final slopes. Twa options exist at this stage. The <br />factors determining which option is taken are rather indefinite and <br />complex. In part it depends upon the dimensions of the slope being <br />produced. <br />If the slope is quite large (high and long) then the most feasible <br />approach is to usually create the final slope in the mining process. <br />That is, as the location of the final slope is approached, it is simply <br />• layed back to the final grade. However, if the slope is not too large <br />it is often mare economical to simply extend the working face to near <br />the limit and then create the final slope with 6ackfill materials <br />derived mostly from the processing. The distinction between a slope <br />that needs to be 6ackfilled and one that needs to be created out of <br />unmined material is not clear. It is a judgement matter. The important <br />paint is that the final slope is created one way or the other. <br />Once the final slope is created then the reclamation process is <br />initiated. For a description of that please refer to the reclamation <br />plan in Exhibit E. <br />• <br />F'AGE 5 OF it - EXHIBIT D <br />
