Annual production from the Munger Canyon Mine is estimated to be 149,000 tons in the f rst <br />year increasing to 897,000 tons in the tifrh year of production. As shown in Table 2.1-I, one unit <br />will be used to realize production during first years. As increased production is needed, additional <br />units will be used with 3 units necessary to achieve production estimated in year 5. Any increase in <br />production units will necessitate modification of mining plans contained in Appendix H. <br />2.1.4 Sequence <br />Surface Structures and Facilities <br />Future disturbances to be associated with the operation include: upgrading and realignment of <br />the existing road, enlargement of the mine site area including hydrologic controls, and construction <br />of the waste rock disposal area. Facilities to be located on the mine site area include: mine office <br />building, vehicle storage/ warehouse building, bulk rock dust storage facility, mine fan, conveyor <br />gantry, portable staginp~ crushing unit, power distribution facility and a coal stockpile area. <br />Construction of the above described areas is scheduled to begin as soon as practicable, after <br />approval is granted. Table 2.2-I summarized projected timing, and area to be disturbed by related <br />projects. All mine related disturbances are included in the proposed permit area. <br />Sequence of Mining <br />Mining projection are described in Section 2.1.1 and 2. I.5 and shown on Figures 2.1-4 and 2.1-5. <br />Yearly projections are shown in these figures for the permit area with all mining limited to <br />development work during this permit term (5 years). Panel work with secondary mining is <br />scheduled to begin during the sixth year of the project. Areas to be affected and permitted <br />sequentially are shown in five year intervals. <br />2.1.5 Resource Recovery <br />GVC proposes to extract coal from the Cameo and Carbonera seams to the maximum extent <br />possible, using the methods described in Section 2.1.1, and in the sequence shown in Figures 2.1-4 <br />and 2.1-5. <br />Cameo seam thickness varies from 5 feet to 26 feet in the mine area and, as detailed later in this <br />Section and Section 4.3.2.3, is found in two splits within the mine plan area. The Carbonera Zone <br />within the mine plan area is split into numerous thin seams. These seams have an interburden <br />varying from 5 feet to 38 feet, and lie an average of 100 feet above the Cameo seam. Carbonera <br />seam thickness varies from 4 feet to 7 feet within the overall mine plan area. <br />Carbonera Zone <br />M~ Page 2.1 - 5 10-12-00 <br />
